I just purchased my e90 M3 and now I'm looking at purchasing track rims and tires and I need your help in determining fitment.

Here is the setup that I'm looking at:

• 18x9.5" rims (Either D-Force LTW5 35 offset all around OR VMR 710 22 offset all around)
• 4 275/40/18 all-around square set up (reason I'm thinking 40 aspect ratio is that the tire that I'm looking at is cheaper with a 40 aspect vs. 35. And square setup so that I can rotate the tires front to back and get more use out of them.)

The questions are:

1. Will this combination work without rubbing front and rear with stock EDC suspension (Either 35 offset or 22 offset)?
2. Will this combination work without rubbing front and rear when the car is lowered with lowering springs (Either 35 offset or 22 offset)?
3. Will the oversteer be much more pronounced than with a staggered setup? I would say I'm an intermediate track rat, but this will be the first time at the track with a rear-wheel drive car. I will NOT be running R-compounds. Previous car was and S4. (Yes, I know it will oversteer more than an S4 ).
4. Do I NEED to get TPMS sensors for a track-only setup? I'm fine with the idiot light being on as long as when I put my stock TPMS-equipped wheels that I can reconfigure the TPMS and get rid of the idiot light without taking the car to the dealer.

Thanks in advance!

The D-Force are nice with lots of brake clearance.

I got these: http://www.m3post.com/forums/showthread.php?t=382667

You can get 9.5 front and 10 rear or 10 all around. They'll clear Stoptech's but no Brembos.
There's no NEED to get TPMS.

I believe 275/40/18 will rub up front almost 100% sure.

And that's without lowering it.

I've run the VMW 710 with et 22 with 18" 275/35 tires with no issues, even lowered on H&R. Lots of tires in this size. Many people using this tire size with the D-force wheels with 12mm spacers.

The square setup works well. My main concern is dialing out the understeer.

Ask Frenchboy about TPMS as his came on at the track a couple of weeks ago and he had to replace the tire. Probably safer to have TPMS.

So what about 275/40/18's? The reason I'm looking at 40's is because the tire that I want is cheaper than 35's. So if 35's on et22 in the front are fine, will 40's on et22 be fine as well?

The answer to all four questions in your original post is "no". They will rub at the front, springs or otherwise, there won't be an oversteer problem and you can get by without tpms although it's dangerous.

275/40 x 18 tires are too tall and will hit the fender liner regardless of offset. 22 is the right offset, by the way. 275/35's will fit because they are the same height as the stock front tire.

Yea go with the 275/35. Very popular sizing for the track guys. With the 22 offset you should have no rubbing problems.

Can I suggest the Advan RS in 18x9 +22 for a track setup. Made for the track, light weight, and strong.

Way too narrow for a 275 for on the track.The minimum is a 9.5 with a 10" being ideal.
