Anybody tracked with Apex 18X10 ET 25?

I need to order track wheels and tires for my incoming M3. Has anybody run these with a square setup on track with 275/35/18's? Any spacers needed? Any rubbing? How is the balance and grip?

Thanks!

through my searches it seems like this is a pretty popular fitment and generally doesn't require spacers ... I don't know how feel/traction is but 275s seem like a sweet spot as a square setup. I ordered 18x10et33 because IMO the et25 is too aggressive looking. I'll be running a 10mm spacer up front & nothing in the back.

are you looking for a track only setup or dual duty?

That is what I ordered. If you do order, ensure you order the EC-7, as they are the only 18" Apex that will fit over the iron rotors. With ET25, you will not need any spacers. Front should be a perfect fit with the rears sticking out a little (equates to 15mm spacers). The ET33 combined with 5-10mm spacers in front is also an interesting option. The reason I went with the ET25 is mostly because they were not offered as part of the group buy. Further, I prefer avoiding the hassle of spacers.

Thanks for the feedback! I wussed out and went with similar to factory size and offset..HREs in 19" with Michelin Cup 2s in factory sizes for track duty. I can always try a 265/295 19" hoosier r6 setup as well.

I don't think many would consider going HRE wheels with Cup 2's as "wussing out." That will be a great set up, I'm sure.

. I guess not, but I envy those with 18's and wider tires!

Now if I can just find some RS29 pads in stock somewhere I'm set! Everybody is out so I might have to go with carbotech.

+1. ET33 with 10mm front spacers would be perfect. 275/40 or 275/35 would be fine for tracking.

Reviving this thread a bit.. I'm looking to move to a square setup to try to reduce some of the understeer and prolong tire life on the track.

CanAutM3 - any pictures with your 18x10 ET25 setup? Any issues with rubbing on track? I'd prefer to go without spacers if possible.

Thanks!

Very happy with the 18x10ET25 setup thus far. No rubbing at all. As expected, the front is a perfect fit and the rear is a little more aggresive, but still fits very well. I am waiting for Apex to release an 18x11 wheel with a more suitable offset for the F8X so I can buy a pair and fit 305/35 in the rear. Here's the only pic I have available right now:

I run the 18x10 et25 with 285's square, I had to put a 5 mm spacer upfront to clear coilover spring perch, I also run -3.5 deg camber upfront. No rubbing issues. I personally believe you could go 295s square without any rubbing on that set up on oem suspension. I also had no rubbing issues when I had oem suspension

What coilover suspension set-up do you have?
