Will a sunroof make a 240sx slower and heavier?

[OBOYz3Hunna]

Will it have a substantial amount of difference in weight and how fast the car will go?

[Driftwurks]

I highly doubt it. I would only care if it was a dedicated track car.

[future]

I really think the whole less stiff thing is in people's head. Where is the proof?

[OBOYz3Hunna]

What do you mean less stiff thing? Does a sunroof make something stiff? im new so bare with me :)

[xoxide]

Depending on if your a Loyal sunroof displayer, or a Hardtop coalitioner, yes a sunroof will make something stiff.

[Bmxer300zx]

wow really? put a cage in it if your worried about flex.
i'd worry about turboing the slab ka or a swap before being worried about your car being "slower".

Fuck yes made my day right here

[ManoNegra]

Marginally... issue is they leak, whistle and or get stuck for the most part as they get older and weather the elements.
Also taller people have a hard time fitting in them with a helmet and cage at the track.

[roboticnissan]

I really think the whole less stiff thing is in people's head. Where is the proof?

Stiff chassis definitely makes a dfference, but i hate when ppl tell me that erhmergherd my rear strut bar is making my chassis soo stiff. The only way i see anyone feeling the dfference is a pro racer who driver his race car for hours a day everyday.

[Matej]

Sacrificing the daily luxury of a sunroof is so worth that one time you take your car to the track and beat all the other race cars hindered by their sunroofs.

Truth! hence why nascar drivers have a solid roof.

This is one of the dumbest posts that I've ever seen.

Chassis flex is real, guys. And if your car is a track only car finding a solid top helps.

[Juantwo3]

sun roof gets the ladies, end of thread.

[holemilk00]

This is one of the dumbest posts that I've ever seen.

Chassis flex is real, guys. And if your car is a track only car finding a solid top helps.

And this is one of the dumbest statements I've ever seen. Unless you have chassis flex data showing that an s13 or s14 has more flex with a sunroof verses without then you're talking out your ass just as much as everyone else. There is a lot of extra bracing in sunroof versions of these cars. So unless you have the data to back up your statement you should probably just be quiet.

[DRIFTER-M]

Depending on if your a Loyal sunroof displayer, or a Hardtop coalitioner, yes a sunroof will make something stiff.

:keke:

Made me lol for sure!

[zooopreme]

Because old (heavy) sunroof assemblies provide plenty of bracing and stability compared to uncut metal, right?

I would be under the impression that the structural rigidity of metal would be compromised when cut and that the sunroof assembly wouldn't put back what was lost. And speaking of flex, I'm not saying chassis flex would be like paper in the wind.

[Trap Star]

Unless the primary use of the car is track days I feel like the main issues are headroom and leaks. I'm 6'4" and I used to bump my head on the headliner in my s14 pretty often with the sun roof, so if you're tall it will be an issue. Other than that I'd mostly be worried about leaking. I don't know how much it costs to do a sunroof but considering the average price of a 240 is pretty low you might be better off finding one that has an OEM sunroof and just transfer any mods over.

[future]

Just as I said. Nobody has proof. I believe it's all in people like zoo's head

Just bull shit other people day and other believe. A vert. Yes I could see that. But them again you have cars like miatas and s2ks that are ment to be more of a track car. And have no tops.

So until I see real proof which we will never get. It's all in your fanboys heads. Sun roof or not your 40 is going to flex. Hell it's a rolling death trap

Miatas flex for days, how do i know this? I drive and race them. Going up driveways you get hardtop creak, add a full cage and no more creak. A cage is ten fold than that of a sun roof tho

The OEM sunroofs are probably designed with extra bracing to prevent any chance of additional flex. I doubt any aftermarket install is going to have that kind of engineering behind it.

[future]

^^ don't know much about miatas so thanks

And ^ I'm under the impression that he is looking to buy a 40 with or without a sunroof. Not installing a after market one. Based of the OP

[Trap Star]

Well then hopefully he's short and doesn't mind wearing a wetsuit if necessary while driving in the rain.

[Bmxer300zx]

lol if it leaks fix it and don't be lazy. My z32 t-top leaked was as simple as ordering a gasket if ya can't replace that you have problems.
Also a manual sunroof i doubt has hardly any different flex than a solid considering the bracket system that's built around it.
If a car has t-tops or c-top i can understand that. Z32 owners eat up a slicktop z to have for the track in order for a "stiffer" track car.
.
To o.p, dont worry about this it's the last thing to worry about.
Get a sunroof cause when you remove your a.c for 5 whole hp u'll want it.
worry about a turbo or swap to go faster, then when you care about 20lbs take a big dump and fast for 3days prior to track meets.

[collegekid]

Op do you have a popup or a sliding sunroof?

If your car came with a sunroof chances are your sunroof drain probably has rust.
Mine leaked, and has rust at the sunroof drain. As soon as I crashed and the sunroof wouldnt stay down, I immediately had someone weld in sheet metal.

The thing is, 240 roof metal around the sunroof is very thin and flexible. I don't think the metal on non sunroof cars is super duper thicker than non sunroof cars.


It's negligible, so just fix your sunroof motor (leak or whatever) and get a cage if you are so worried about flex

[Scope240sx]

:picardfp:

[Mofuhcka]

LOLOL OBOYZ3Hunna best fucking name on here aahahahah

[Kingtal0n]

I dont know much about chassis flex or integrity, but I do know that I prefer not having a sunroof. Simply because the weather strip is so difficult to change, and if it starts to leak, you have a wet problem.

There are many ways you can make the chassis stiffer, I am sure. I would start simple, a bolt-on part for instance, like a strut bar. Then drive the car and feel it out. Then add another piece.
I am speaking from daily driver perspective. Dont go overboard, take it slow, otherwise you cannot tell which part did what to the handling.

thc you go fastst glass over metal yyeaaay

[KiLLeR2001]

Take away the glass and what do you have? A giant gaping hole of fail. Why not make the whole roof glass? There is glass in front of us (a windshield), glass to the side of us (windows) and glass to the rear of us (rear windshield). For what reason? Vision. In no way shape or form do we ever need to look up into the sky while driving, aka a sunroof. I guess since this is the year 2012 people are more intrigued to get a sunroof so they can look up in the sky for an impending catastrophic meteor set course for earth.

Good luck with your creaks,
Good luck with your leaks,
Good luck with your busted seals,
Good luck with your car's rust, they say it never heals,
Good luck with all that sunroof crap, for it is not for me,
Give me liberty or give me death and my hardtop S-Chassis.

THC 4 lyfe mfers!!! Holla.

[2muchboost]

Lol there is some real sun roof hate in this thread. I guess I am lucky, havent had any issues with my sun roof ever. Mechanics and trim are still good and functioning.

Will it make you slower, not enough to make a huge difference. Does it make it heavier....not significantly. So dont base any decision for your cars performance on the sun roof other then aesthetics, whether or not you want to take a chance with roof leaks, and personal preference. Trust me I dont think my 95 SE sun roof will play a huge factor once my 2jz setup is up and running lol.

[GhostlyCoupe]

You could just jog twice a week more and lose 15 lbs.

Then you can keep your sunroof and still lose weight from the car.

I have both pop up sunroof on both of hatch. They dont leak so i dont really care.

Changing of the topic. bigs is defeated yet again. Victory!!!

[holemilk00]

Do you people not realize the only sunroofs that get talked about on here are the ones with problems?? That's why you guys think they all squeak, leak, and fail. I have two power sunroof cars, one flip up (hatch) and two verts. None of them leak, they all function as they should, and other then one vert the rest are squeak free. Start looking at the whole picture you closed minded fools.

[towlie]

This one time I was racing this guy. Goin hard he almost had me. But then I remembered, shiiii, I got no sunroof!! This cracker had his popped like a can of Pringles. Felt that whoosh from the non sunroof roof, instant speed !! Blew sunroofs doors off, got the pink and never raced again, my car is to fast from lack of sunroof

If you can admit that a car with a sunroof will leak at the roof before a hardtop will, I'll be satisfied.

Probability of a hardtop roof leaking: 0%.
Probability of a sunroof leaking: Some statistical percentage greater than 0%.

Thank you!
my civic, z32, accord, volvo! and current car that opens and pops up doesn't leak.
My z32 got a little drip after 1.5 years went on z1 bought a replacement WOW so hard to replace.
I like sunroof you'd be surprised how much more air flows through specailly a sliding one.

1. I won't admit that because if you care for both of the cars neither will ever leak.

2. A hard top doesn't have a 0% chance of ever leaking. They can leak as well. Around the window seals, here in florida cars rust from the top down, so it could rust. So I'm sorry I have found a fallacy in your premise.

[!Zar!]

You all sound like a bunch of fucking girls.

[Bmxer300zx]

ha ya between the windshield, hatch and the way nissan designed the windows to seal, the probability of ur car leaking from the roof line is about 100%.
it's called taking car of your shit, same as a sunroof/moonroof/t-top/c-top.

[fliprayzin240sx]

This is a serious topic?!?!

[drscooper]

we should all just cut are roofs off and be as one!

[KiLLeR2001]

Are you suggesting that only the people who don't take care of their vehicles experience sunroof issues? Even if a sunroof leaks and you fix it right away, it still leaked!

2. A hard top doesn't have a 0% chance of ever leaking. They can leak as well. Around the window seals, here in florida cars rust from the top down, so it could rust. So I'm sorry I have found a fallacy in your premise.

The argument isn't that a hardtop vehicle can't leak. But rather can it leak from the exact section of the roof that the sunroof exists on. And since a hardtop is solid and not cut, the probability is 0%. Don't say rust either. Because if you take rust out of the equation a sunroof can still leak!

All I hear on CR is "I want hardtop". Then when they get the hardtop they complain about creak; you can install hardtop brackets to eliminate it btw. What I do think is funny is when they complain about their firewall having so much flex and go ahead and install this.

[sterlinge]

Got to get a Sunroof if you want to be fancy!

[EDacIouSX]

I have a sunroof, wish I didn't. Takes up a lot of space.... Also, the sunroof adds like 70-100 pounds or so. It's a substantial difference. You gotta count the weight of the bars that are on the chassis itself too.

[Hashiriya415]

Roof is just skin. Simple test is, if you press with your finger and it flexes, it doesn't do anything to chassis rigidity.
However when you cut off the entire pillar bars, it makes a difference because that is the structure and it runs under neath the roofs skin.
I know a little bit about chassis flex because I used to drive this every day as I was cutting it down, and even drifted it as shown in pic below, without seat belts and doors.

[KiLLeR2001]

^ ROFL. Now I've seen it all.

[Hashiriya415]

Actually I cut even more then it shows in the pic, I cut everything in the front from the strut tower, it didn't even have a radiator support, the radiator was held only by the hoses and had AC fan. I drove this car from my house in SF, to Pacific and tried to grip through the mountain but wasn't stable.

[Hashiriya415]

wow wtf. did you even make a thread about this?

[Hashiriya415]

Does it deserve a thread?
I have like 20 pics of it, also like 20 pics when I was building the colorful black and blue engine.
I was gonna cut it even more, but these retarded ass undercover cops started giving me shit. Regular cops stopped by my house cuz I was working on the street, so they just wanted to see if it was stolen and nothing more, they just asked me how I was doing this stuff and I was explaining them how saw and sheers work and how a car is constructed mostly from thin sheet metal.
The undercover cops gave me ticket cuz registration expired and wanted to impound it the next day if I didn't move it from the street. Cuz I kept parking it on street in front of my house.
I was gonna actually cage it, and track it, but I got too many other toys and in SF parking isn't easy. People fighting like its last bread on shelve. Calling DPT as soon as I leave something 72 hours. (lazy fucks can't park their POS 3 blocks away and walk)
I only have one garage spot, my track car and bike is there. So rest of 5 cars, and a car trailer are on street.

[illvialuver]

Holly shit, how is this thing 3 pages, and I only read the first page, but the biggest reasons NOT to get a sunroof is....

-the reduce headroom
-the make noise
-girls dont give a shit if you have one, and if the only reason a girl is dating you is because your car has a sunroof, you have some considerable problems.
-not that you would feel it, but you are raising the cars center of gravity by adding roughly 100lbs to the highest point of the car.

Newbs today post so much lamer shit than newbs 8 years ago.

[Hashiriya415]

its super easy to rid of sun roof. Buy some 20 gauge sheet metal $10, draw on cardboard, transfer to sheet, cut with sheers. Then weld in and sand down welds till smooth and repaint.

[EDacIouSX]

-not that you would feel it, but you are raising the cars center of gravity by adding roughly 100lbs to the highest point of the car.

Its true though. Simple common sense, like stated before most people wont feel it, but then again I doubt all the people that rave about z32 aluminum uprights making such a HUGE difference over stock. So who knows.

[Bushido]

held a sunroof assembly in my hands the other day, damn that shit is heavy.

[Howie Felter Snatch]

Oh my god people... Having a sunroof versus not having a sunroof HAS ABSOLUTELY no impact what-so-ever on the chassis rigidity of a 240SX.. The roof skin is just a piece of thin sheet-metal covering your head and whether or not it has a gaping hole in it or not, the structure comes directly from the roof-frame that is basically just the whole perimeter of the roof itself. How can you all be so retarded? lol.. Just look at the roof of your 240 and you will see that the actual roof itself is just a flimsy piece of shit either way you look at it; sunroof or not.

The actual structure of the roof is what the ROOF-SKIN is attached to, part of the actual uni-body frame itself. And guess what the sunroof is attached to? Yep, that same old flimsy ROOF-SKIN.. So hardtop or sunroof, it is all completely negligible, stop the fanboyism and stupid talk and just go track your fucking cars already, enjoy your lightweight FR-RWD car and stop bitching about sunroof vs hardtop. Geesh.. Come the fuck on.. And don't even think about telling me about that flimsy brace that runs up/down the middle of a hardtop 240SX because that shit is held on with SNOT & PISS since the roof-skin is so damn thin..

The only negative thing I can envision about having a sunroof is simply weight and that weight is negligible on hatchbacks with pop-up sunroofs because that shit weights like 20 lbs max... Even so, who gives a shit, go on a fucking diet you fat-fuck and there, bam instant weight-reduction! LOL!

IF you don't want chassis flex, then properly stiffen up the chassis with appropriate chassis bracing components or a roll cage. NOW someone quickly close this damn thread already! :)

Yeah except the entire assembly is more like 70 lbs not 20 (according to sources in this thread). I would imagine the S14 setup probably weighs more.

Killer2001 was sexually assaulted by a sunroof as a child. Those leaky, overweight, transparent bastards.

[mikeys13]

A sunroof and its components obviously weighs more than just thin metal. So power to weight ratio yes it will because more weight. The real question should be is it noticeable on the butt dyno? Which I'm pretty much guaranteeing it to be no. I don't see why is such an argument. It's pretty much obvious and it won't make the difference between losing a race. Overall stupid post.

[LOUD240]

I dont know where you all are getting your info but the nissan electric roof only weighs like 45lbs , I had a ASC sunroof in my hatch and it only weighed 32lbs
http://i609.photobucket.com/albums/tt171/loud240/240pics031.jpg
And it was worth every bit of the weight to me , you either like sunroofs or you dont.30lbs is not going to make a single bit of difference in any of the normal interior stripped drift missles on this site.

It's your life goal to tell people how much you don't like sunroofs. You have bigger problems to worry about. Like how an S15 ended up on your front end.

[DenkiMan!]

with a helmet on, i dont have enough head room to sit upright in stock s14 seats. at 6'2 i still kind of have to crouch even with the sunroof, but since i dont have bucket seats to sit me lower than stock seats, i'll have to be a sunroof guy. i imagine its like this for other tall people?? the car will only perform as well as you drive it, so chassis flex or no chassis flex, nothing good will come out of a driver sagging like a west coast crip in the drivers seat.

[T chop]

S13's look so much nicer without ugly sunroofs

[Bmxer300zx]

o man this thread still goes on about how fast a stock 240 sunroof vs no sunroof 240 is?
answer they're both SLOW buy a SWAP or Turbo!
i'd hate to see the arguement a roof rack would cause lmao.

[iBlaze240]

Well I have a manual pop-up sunroof/moonroof, don't really know the difference there, but I love it. More airflow on hot days when it isn't necessary to run the AC. I can remove it entirely or just leave it propped, it doesn't weight much, definitely nowhere near 20lbs. It's like 6-7lbs. I can remove it right from my seat inside the car and throw it in the back seat. I hear the power roofs that slide into the roof, not outside the roof, SUCK because they decrease a lot of headroom and the mechanics get fucked up easily. But I really don't think it is something to worry about with a pop-up roof and I doubt you would notice any difference between having it or not.
