This was mentioned in a 3rg gen thread that M2 and I think someone else had that setup without rubbing...is that possible?

If so, what offset's? Where are the tire guru's that answered before?

 

Max will have to respond to his question...I'm growing weary...

 

I think I found this from the same thread I read earlier.
In the tire section says he runs 18x10's on the track.

Max and I both run 18x10 CCWs on all four at the track with 285-30s. Call or e-mail John at Complete Custom Wheel to get offsets (www.ccwheel.com).

For me at least, one of the keys to avoiding rubbing is running the ride height at relatively stock levels. I like the way the car works best at that height anyway. If you want to run the ride height really low, you might run into rubbing problems.

I have done three or four track events with the wheels and they only rubbed once, under full braking and full steering lock (oops!). They caught the fender lip just a bit. I was able to bend it back without any paint cracking or cosmetic damage. I raised that corner up a turn and haven't had any trouble since.

Here are pics and info from my web site:

Nothing worse than spending money then after wishing you had bought something else. I was going to go with 17x8.5-F & 18.9.5-R.

I was originally looking at the Blitz 03's, they just look sweet. No one can tell me what they weigh but supposedly not light.

So if I can get the correct backspacing, i'll get the Racing Hart CP-035R...else CCW.

One thing I don't understand though?
* Doesn't the backspacing or offset have to be different for front and rear? ...if the same, that means tires can be rotated.

I allways thought you needed more backspacing in front or had to use less width?

Thanks guys, you rule!

 

The valspeed site is mine.

I run the 18x10's all around at the track and on the street. They have 53mm offset front and rear, with 285/30-18 tires. I, like Max, run at relatively stock ride height, and as he mentioned, that is the key. I don't feel it necessary to lower the car any further. Even on the street I don't have any rubbing except when I hit a really big bump or pothole.

Other factors that are going to matter in this regard is your overall suspension setup, i.e. spring rates and dampers, bump stops, and even anti-roll bars.

Ah..well stock front to back is 50mm offset..so what makes you think you need different offets...

I thought alot about doing 18x10 all around..but then really thought about it more and realized I'm not tracking my car an awful lot..so I went with 18x9 and 18x10..both with 50mm offset..I may be slightly lower then stock..if any at all..

 

I run 17x8.5" and 17x9.5" wheels on the street. When I drive around on the street with the 18x10" wheels on (to go get gas or back to the hotel after the first day of a track event), the car requires more attention to keep going straight, because it follows grooves more easily -- more "tramlining" I think it is called. There is a cost for running really wide tires on the front, but I certainly understand the desire to get more rubber on the road. Just be aware that the ride will be more harsh and you'll need to give more steering input.
