coilover questions

hi guys i just recently bought my 97 240 in june and im anxious to start modding it, i was going to get tein coilovers but since im new to the modding game i wanted to know would that be all i need? i was told i would need control arms etc. if so, what would be a good brand and set to buy? i dont want the car slammed cause i live in brooklyn n.y and the streets here are horrible plus it would be my daily driver, but i DO want it fairly close to being slammed. Any advice and choices on coilover brands would be greatly appreciated thank you.

Megan -> Stance -> Tein -> DG-5

Pick one, thats the order of budget and performance I'd say as a general idea. Do some research, find what suits your budget and goal and go from there.

you dont have to do any further upgrades if you want to get coilovers.
buy whatever coilovers you decide on , install them , go drive.

spl has a detailed list of parts for suspension and as im looking at the list i feel like there are some things in there that i wouldnt need, i just want my car lowered with a nice stance, sway bars i know i would need along with a strut bar, tension rod, rear upper arms. i dont know what else i would need after what i just listed, im not looking to race so any extra parts needed to give me an advantage isnt really my concern, i just want my car on coils with a nice stance, so if someone can give me a direct and detailed list of parts to buy, i'll really appreciate it, thanks to everybody for their opinions and contribution on my thread so lets keep em coming

Powered by Max in my opinion is the best. ive had Megan and Tein and PBM are better. but get whatever you want put them on and drive. RUCAs would be a good idea. and if you go really low and have a aftermarket exhaust its a good idea to get spl exhaust hangers or just use the old worm drive clamp trick.

Lets be serious here Zilvia, the answer here is simple: The cheapest coilvoer he can buy. The OP isn't going to be tracking the car, so no need to spend money on anythign remotely decent.

Any coilover in the 750-850 range will be perfect for you. You can lower it to the frame rails, and it will make the car feel stiff. I'd say just get the Megan Racing or Isis ones. Don't listten to these guys that say they are shit, as their 1200 dollar Teins or Stances are realistically no better, aside from the powdercoating. Ultimatly anything under 1500 bucks, or custom is entry level/street oriented so you'll be fine with any brand. Check the Zilvia Sponers section out for the best deal going.

Also: Do you have any friends that are into cars? If not, I'd sugest you find some to help you...seems like you are very new to this.

Also: You can install your coilovers, and drive all in the same day, without issue.

I am glad someone else asked this question.

Aside from performance. Is there anything else suspension wise the car could benefit from on a RELIABILITY standpoint that should be installed along with coilovers? I understand that coilovers drastically change the movement of a car's suspension components and I'd imagine it being more stressful on the car. Forget tracking the car, just from a reliability standpoint.

The answer to this is two fold:

In reghard to stress related/damage, you will be perfectly fine puttin them on and driving. No worries here

HOWEVER

If you are going to lower the car a decent amount (persay, a finger gap from fender to tire) you should really look into getting an alignment so you don't scrub your tires off down the road. Do you need to get RUCA, or Rear Toe Arms? Maybe not....but for the cost of the lesser brand (ISIS, Godspeed) it may not be a bad idea to get them for the rear, to help with a proper alignment)

No, the list I said was in order from Cheapest to Best.

You DO NOT need anything side from the coilovers to install them. It is not really 'more' stressful to your car unless you drive over potholes all day on purpose. Rear Upper Control Arms (RUCA's) would be beneficial like other people have said, but far from necessary.

Since I doubt you'll be installing your coilovers yourself, I suggest getting an alignment at the shop that installs your coilovers while your there. If you "want" more suspension parts you can feel free to buy them.. however usually the more aftermarket and performance parts you add to your car, the less daily drivable it is. So, if you get coilovers, control arms, tension rods, toe rods, sway bars and the like.. your car WILL feel stiff as shit and not be nearly as comfortable as if you'd just bought the coils themselves. I suggest the Megan Racing Street Type coilover for you. They are about 1000$ and will be soft enough for driving daily (on the softest setting), will be sufficient for lowering your car and give you a quite a noticable difference in handling and what not.

Thanks for the info fellas and thanks to soleprime for bringing this up. I'm also new to these kind of mods so I wasnt sure how much was too much for a daily driven car. As of now I have a complete set of new Stance GR+ but havent installed them because I wasnt sure if the toe rods, ruca, traction and tension rods were a must. If soleprime doesnt mind, i'd like to ask two questions. The benefit of having rucas and rods on a daily driven car would be achieving good alignment. Just how good an alignment can one get with coilovers alone? I'm asuming this question may vary depending on how low you position your car. How about what codyace said, "a finger gap from fender to tire". Second question, Datenshi mentioned the more aftermarket parts your car has the more uncomfortable it feels. I havent had a chance to ride on someone's car to feel for myself so i'm curious, if you install the toe, traction, tension and rucas, would that there give you an uncomfortable ride?

It all really depends on your definition of uncomfortable, which is really the problem it's self. Everyone on here is just giving you personal preference and their personal opinions.. what is stiff or soft to one person may be completely the opposite to another person. Just like most opinions on the internet.. :P

In my opinion it wouldn't be too bad, but that being said I have PBM Coil's and some say they are too hard for daily driving even on the softest setting, I don't really find them that way. You do not really need to install any other suspension parts, unless you are going to use the function that they provide. i.e Toe rods to adjust your caster and toe, RUCA's so you can adjust rear camber, sway bars to reduce body roll, etc..

Personally, the only thing you would normally need if you've got big wheels is RUCA's so you can adjust rear camber.. as most coilovers these days come with camber adjustable fronts already. If you're going to be slamming the shit out of your car, I would suggest more suspension parts like toe rods and tension rods as they are higher strength than OEM ones typically and they are more meant for that.

Otherwise if your just lowering your car, hardening up the suspension a bit with your coilovers and would like to enjoy a semi-comfortable ride.. just install your coils and that's it. You'll find out quickly after having your coilovers installed what your limits are, what you enjoy and what you would like adjusted and new things you should buy.

As stated above guys, the RUCA and Rear Toe Arms are not *needed* in the sense that the car will still drive safely....


HOWEVER

When lowing an S chassis (and I'm certain anyone with coils is easily lowering their car 2-3 inches at a minimum), you can be damn sure that your rear toe will be terrible and eat your rear tires up super quick. Sure there will be camber to deal with as well, but camber won't wear away a tire nearly as fast as rear toe.

So IMO, I'd suggest at least getting rear toe arms if anything, as you can zero out the rear toe and save your tires, while just dealing with the camber until you can get RUCA

so basically the essentials if you're just trying to lower your 240 to get a nice stance would be: ruca and rear toe arms from what im hearing so far.

Don't even worry about the RUCA (Rear upper control arm) unless you plan on tucking 18's on the rear.
Install your coilovers, get an alignment, if your rear toe is really far off, THEN get the rear toe arms. Coilovers are just fancy struts and springs, your suspensions basic shape doesn't change just by installing them.

I would start by checking the condition of your bushings before worrying about coilovers
are your tension rods, tie rods and ball joints cracked or leaking?
are your steering rack bushings falling apart?
take care of that first

now coilovers
yes, you can just throw them on and drive
but
if you care about alignment and tire wear
you'll want to have at least RUCAs
depending on how low you are, you may want rear toe rods aswell

get an alignment after
