Default Re: Square Setup Front Tire Size

Looks like youíre running KW V1, assume that is a progressive spring like my V2. With my Apex EC-7 (18x9.5 w MPSS 265/35 square) I just tickled the fender liner. That was with GC camber plates running about 2.7ish degrees of camber but I have to run a 12mm spacer in front to clear the spring. If you have less interference from the spring you wouldnít need as aggressive a spacer (maybe none st all as someone else suggested).

Of note Iíve since moved to a different setup for track and I ended up rolling/pulling fenders and going to -3.2 camber to tuck some Nitto NT-01 275/35 under the front. Wheels are the BW TE:AL TA-16 18x9.5 et 22. Hits the fender liner but not the actual fender.

+1 on alignment dependence, but you don't need (-) toe unless autox. Def not for street or long course track.

Default Re: Square Setup Front Tire Size

I run 265 35 18 square setup. I think 30 series tire in this size is a bit two little side wall for the street. The 265 35-18 is a much easier tire to find in all brands. I like the Michelin Pilot Super Sports or the new successor the Michelin Pilot 4S.

You want to run FULL caster and just a tad toe in to minimize tramlining. I really don't have that problem at all. Tramlining also has something to do with the type of roads you travel on. I can't say I've ever experienced any tramlining with my setup in South Florida.Partially because of the road surfaces, and partially because of the alignment....I surmise.

D-Force LTW5 Wheels 18" diameter. 9.5" wide. Black. ET35

For this et35 wheel, a 12 mm spacer in the rear is the proper spacer. I'm a little sorry I didn't buy a 15mm spacer because I got plenty of room because I rolled my fenders. (For when It used to run a staggered setup and wider tires in the rear).
but I love my square set up for so many reasons. I think I will be keeping it.
I have the typical drop of 13 1/2 inches in front and 13 inches in the rear. Measurements of the wheel to top of fender. Zero rake.

Michelin Pilot Super Sports are assymmetrical but not directional tires. You can rotate the heck out of these tires to maximize their life.

A much cheaper option are Firestone firehawk Indy 500's
but I don't have any first-hand knowledge about these tires.

Stay away from using 5 mm spacers in front. they have a tendency not to be hub-centric and I could never get my wheels to run correctly. I just figured out other ways to not run any spaces at all in front and I don't have any rubbing issues.

Getting your wheels dead center when you're mounting them and doing the perfect star pattern and 88 foot pounds of torque on the lug bolts makes a really big difference in how
your car feels. you can wire wheel and clean your lug bolts but don't use any lubricant on them like never seize. if you are tightening them properly to 88 foot pounds of torque and rotating your tires regular you will never need never seize. All your lug bolts will come right off with no fuss.

100% agree with this. I have run a couple different square setups and currently on Rear CSLs with 265/30/19's. 30 is great for the track but not great if you have bad roads (NYC...). Any hard pothole hit will likely damage a wheel/tire.

Default Re: Square Setup Front Tire Size

My plan is to go 265/30 just like the current rear setup. I assume spacers won't be required given the wider width and +27 offset?

This might be a dumbass question, but does any one if having staggered tire sizes will have negative effects? i.e., if i went with 255/35 in the front and kept the rears at 265/30. I don't care about rotating my tires. I'm adding the two rears to the front for aesthetic purposes only. I don't drive my car enough to care about getting extra tire life.

Default Re: Square Setup Front Tire Size

I dont run a spacer on the front, and run a 12.5 spacer on the rear. You need some camber on the front, I run 2.5 in the front and 1.5 in the rear. I'm biased, but I think it looks perfect . Here are some better pics.

I really don't see any good reason to run staggered tire, 265 is the perfect fit for these wheels. They aren't overstretched or mushroomed. IMHO 255/35 would look weird. Side note this site is a great tool for fitting wheels/tires.

So far three people in this thread have heavily advised you NOT to use a 30 series tire. Trust us. 265/35-18
Square. Tiny amount of toe in front and rear. FULL caster.
Front Camber -2.0 Rear Camber -1.8 Front Toe IN .18 Rear Toe IN .23

All 265 are not created equal. Some brands are a LOT wider than others. (weird, huh?)
Use -2.0 camber in front if you can get away with it for your particular tires. Go -2.5 if you have to.

Avoid 5mm spacers because they are not hubcentric and it is harder to get your wheel PERFECTLY centered.

My specs are a slight modification of the build journal's "Sporty" set up. GREAT website BTW. Explore.
