Fronts is next:

I've been running 265/35/18 up front on 9.5" wide and +20 offset.
I can't go any lower offset bc the wheel will touch the springs on the coilovers.

I have tein angle spacer on the rack and hit all over the inner fenders and have rolled and pulled the stock fenders. Just in negative offset and spacer, you're eating up 31mm.
And your wheel is wider, so it will poke an additional 18mm.
So you'll need 50mm front fenders.

* on both of my posts above, I haven't taken into account your stretched tires.

You will gain some clearance from that alone, but it's hard for me to estimate because all tires are different.

If I were you, I'd be putting 335's in the rear and 315's up front.

Good luck!

The links above have people running -7 18x11 with 30mm fenders 3.5 camber.. So something is wrong in the math of all this.

What's the smallest tire I can fit on the front rim and still be... Semi safe lol

you can go with a lower offset that will push the wheel further from the coil. a higher offest will bring the wheel closer to the coil.
for instance youll have more clearance between wheel and coil with a 17x9.5 +6 compared to a 17x9.5+35

i just dont wanna see the op by shitty wheels due to a post but this thread should really be locked

Shalezzz thanks for your post: but as stated there is no one els that is doing this kind of fitment that I have seen. Again as I have said I asked this in the wheel and tire thread and still have not got any input.. What and where and I supposed to go if a sight for s13's aren't helping out with questions? I am all for following the rules but I believe this topic will help others that have the same questions down the line.

Perfect, I am doing the stretch tires look so that will be a big help.

The tires I have posted in the first post is what I currently have. 245 in front and 285 in the rear I think. I want to go smaller on both of those so the 335 and 315 is not really for me. If the car was not my dd and just for sliding I would have no problem with doing that bowing the fenders and giving it a ls1 and calling it a day.

Sorry that was a typo, but it should have been evident by the rest of my post.

I meant higher offset.

And by the look of things, the OP has already purchased these ill fitting wheels.

The tire is the difference. The math is solid.

Check it yourself on willtheyfit.com

heres 9 cars with the similiar size wheels. just subtract 12.5 from the offset and that will give you a 12.5 inch wheel so 18x12.5 +13 is basically 18x12+0
RIMTUCK.com - Search Results - Data
people are giving you shit because instead of figuring out what size suits your needs you bought the biggest wheels possible and expect people to hold your hand and give you precise information to make them fit. figure out what stretch you want, tape the over fenders to you car if its reasonbly close, increase the camber. if its not resonably close bow the fenders, or sell the wheels

Khoda

Shalezzz please don't talk out of term. I didn't buy the rims for you to put them on for me. If that was the case I would go to a shop give them a grand and say fit the rims. I am just looking at tire stretch and inner body clearance. I just installed full baggs on a car myself. I don't need anyone's to hold my hand.... But again this is a area for helping other... Don't need to help... Just don't post at all then.

Now with you saying just subtract 12.5 from the offset and that will give you a 12.5 inch wheel so 18x12.5 +13 is basically 18x12+0.... That does not help me on my tire size since I don't see many s13 is 12.5 rears......

if you went to the link i provided it gives tire sizes. i was helping you since you said no one has 12.5. generally people run a 235/40 front and a 255/40 or a 265/35 a half inch isnt gonna be that much more stretch. not trying to be a dick but if you dont know how to make wheels fit dont buy them. for future refence

Khoda

So if you don't know how to do an oil change don't learn and do it? Oh okay so I should just give these wheels away, since you are the expert in this all you seem like a great person to take them....ImageUploadedByTapatalk1383955352.237056.jpg



I know how to do fitment, simply was just asking for people opinion. And said it very clearly if you don't want to help then please don't post anything at all. You my friend are very weird you help then talk crap too? Don't get it. I have been trying to be very polite, I come from BMW posts and the people there are helpful and happy to post up valuable information. Just sucks to see how some people really don't know how to communicate. Must be the age.

I did some searching and can not really find pictures of them on a 11 and 12.5, 235 45 for the front is safe and a solid stretch I think? And the rears I feel like a 265 45 would be good but then again maybe too much? I don't want it to not flow with the front stretch if you get what I mean?


THANKS for the info!

Not to nitpick but a 12.5" wide wheel adds 6.25mm to the poke and 6.25mm to the backspacing vs a 12" wide wheel.

So 18x12 +0 has 6.7mm more poke, and the 18x12.5 +13 is 19.4 mm wider on the inside toward the strut.

OP, you will have so much extra room inboard that you should follow that link shalezzz gave you and pay attention to only the offset and tire sizes. Pick the one that's closest to your setup and use that as a model - doing the math to take into account the small amount of difference in offset.

no, id tell you google how to do an oil change. the reason people wanna lock the thread is because it clutters space and makes it harder to find useful information. be original do it and post up the results. and my age has nothing to do with it, i wasnt even being rude i said dont buy wheels. best advice buy a pair of 17 or 18x10 eurolines put them on the front and have 2 sets of rear wheels so you have spare ones for the track

messed upmsglngth

i was refering the "same" as fender to wheel lip fitment. so i shoulda said 18x12+0 has the same poke as 18x12.5 +6.7. thanks for the correct dont wanna spread misinformation make sure thats right lol

I've never owned an S13 but I've helped people fit wheels on them many times. The problem with S13s like already said is that they have tiny wheel wells, specially in the front. I've tried to help fit some 10js on S13s and they touched anything and everything at full lock. Even if you tub the fronts to get clearance, I still dont see how it wont be hitting the rear of the wheel well on the fire wall side. You can smash it in with hammers but that will only get you so far. 245/35-18s wont do much since thats even larger than the overall diameter of the stock tire size (205/60-15s). Make sure you relocate the harnesses as far back and high as you can.

You dont see a whole lot of S13 guys run 10s up front because of rubbing issues. I know guys who hates their 9.5j +12s because they rub. I've run nothing but 10js on the front of all of my 3 S14s and I know thats the widest I can run on them unless I do some major cutting and welding. Either way, you're really on your own on this since nobody has been crazy enough to attempt something like this on an S13 or even S14s. Rears are not the hard part, its the fronts that will always be a bitch. Good luck to you, hope you make it fit and lets you make u-turns.

^ looks good, but it's widely known that the s14 has much more room all around vs the s13.
