help with size/offsets

[destinyZ]

I've been looking at getting the TE37 SL and I'm about to pull the trigger but I want to be sure so here is what i'm looking at:

(F) 18X10 +20
(R) 18X11 +18

All that I really worry about is the turning radius of the front wheels. LMK what you guys think and thank you for your help.

Also if you don't mind, what tire size should I go with? I think 275 up front and 305 in the rear but LMK what you guys know will work.

why 18?

I would go with 20s. Ilive2win has a nice set. Don't remember the exact name of it but it's the special edition volks. Super lap? Offset looks nice!
Would anyone like to help posting the name?

They are the Super Laps (TE37 - SL). Same wheel the OP is talking about.

I think you are going to be cutting it close in the front especially with a 275 tire. You might be able to make it work with negative camber. Personally I would stick with the standard 19" sizes. They look great!

I don't think the te37-sl come in 20's as of yet.


Just my opinion but i say go at least 19's.

To help you out here...

You will be fine with a little bit of negative camber up front... say -2 ~ -2.3 camber. to add camber up front you will need spc camber arms. The rear will fit no problem...

here is my deal. Why 18's? Yes they are light and tires are more readily available and cheaper but still WHY?

here are my thoughts on 18's... 18's are a cheaper solution but they come with a cost. If you are going for performance and you upgrade your brakes depending on which BBK you get most likely your gonna have to go up to 19's for them to fit. If performance is your concern and your looking for light wheels I can have 19" step lips made in your size of choice... they weigh in just at 19~20lbs all said and done and you get 19's... So its up to you I say go 19's or bigger with 19's being the middle ground of price + performance.

18's is sooo 2001!

^^^ LOL

Yes I was wanting 18's for the lighter weight.

So a 9.5" will be better up front? Will it be ok with a 11" in the rear or should I make it a 10.5"?

That's correct, the largest size TE37 SL's are 19". I'm eyeing those out myself. I don't think you need to go 10" diameter up front. 9.5" will do and it will still accommodate a 275 width tire. At stock height, you probably don't have to increase front negative camber to make the 275's fit, but increasing the negative camber will improve turn in response for sure. If you're slightly lowered, the 275's should fit with negative camber, but there may be rubbing at the fender liner at lock. Do you really need 275 at front though?

As long as your suspension drop is reasonable and the offsets on the wheels are not set too far out ....... absolutely! It provides better balance to match the 305's in the rear. Or a reasonable square tire width setup for the track when matched with a 285/35/19. Plus you won't need a radical negative camber to make it fit. -1.5 camber or less should work.

If done right, I'm sure a 285/35/19 will also fit in the front and I just may try it this spring to see how it works

FYI: I have the Nismo suspension with a 1/2" drop and -1.2 camber all around.

Adding front tire tread width while giving you a larger contact patch will add the following negative attributes:

Tire wandering Aka bump steering
Extra Understeer
Slower transitions
Slower acceleration

Most if not all of these items can be addressed and mitigated *sp* as much as people like running squared setups I typically don't as per my driving style at the track.

Bullitt, I'm planning on a 275 F / 285 R on 20x10 +35 and 20x10.5 +15 rims. From my understanding-

Bump steer: Increases when the rim face is extended further from the pivot point, increasing leverage. With increased offset on a wider rim (+35 on a 10" vs +22 on a 9.5") the maximum lever arm would be equal, therefore no increased bump steer than the narrower wheel. People seem to feel the 9.5 + 22 is acceptable.

Understeer: Everyone except yourself has stated that a wider front tire will reduce understeer not increase it. I have Stillen sways and the front still pushes.

Slower transitions: True, but I will be autocrossing with my original sport rims not the wider 20X10 front I'm planning on getting. I don't expect many violent transitions on my daily commute.

Slower accereration: I believe this will be negligible with a quality lightweight rim.

A 255 section width tire is designed for a maximum 9.5" rim width. You run the same tire on a 10" rim, outside of the designed application.

You say more tire up front is bad, yet you want to go to an even bigger 285 tire in your next setup.

Bump steer is bad, but you want to extend the rim face out even further on a 11" front rim when you install the widebody.

You don't like square setups. Why do all the racers use them? I don't need bigger tires in the back, I don't have 1000HP (I am jealous though)

Don't get me wrong, I know you have the most badass car on this site, and definitely know more than I do. I just hope you could straighten me out on what appears to be conflicting information. Please don't look at this post as an attack or insult in any way, I'm just looking to understand.

A 30 mm increase in wheel width sounds like a lot (excessive) to me. The increased rolling resistance and reduced fuel economy...wow. What tire dimension are you running, Bullitt?

My current setup which is about to change is:

20 x 10 (255 a 265 would be a good choice too)
20 x 12 (305)

My next setup will be along the lines of:

20 x 11 (285)
20 x 13/14 (325 or larger)

Remember I'm going widebody and 1000hp

^ 18's people use for track. IT will lookin kinda goofy without a massive drop
