The best tire options for 305/35 is NT01 or R888R at this point.

I'm running a 305/35/18 NT01 square on staggered wheels. The rear offset is around +34 (11j) I've rebuilt them several times so I'd have to double check what the offset is. The front is a 10.5 +24, again I've rebuilt them several times so I'd have to double check. The issue with the 305/35, in my experience, is the lack of camber up front. I'm at 3.4 degrees, I can get more with the spl arms, but the front tire is still rolling over. The GTS is still a heavy car. I stiffened the front bar to help with the tire problem but it made the front too stiff and it was under steering anyways. Just food for thought on tires.

295/30 and 315/30 is short but may still be the best bet for track work.

I think you might have a different outcome if you had an 18x11 up front with that 305/35 tire.

I'm going for an 18x11 et37 (15mm spacer) on all corners with the 305/35 and see how it goes.

Bimmerworld has released their TA16 forged wheel in 18x11 ET36.

$650 ea. Not bad for a fully forged wheel.

I actually was able to pickup a set of BBS RI-A in 18x11 square et37. Able to run a 10mm spacer up front and still fit a 295/30 or 305/35 easily.

Do you have any close up photos of the wing mounting to the stands?

Of course, does this work? FYI this is the GT4 APM wing with GTS style mounts, not for GT4 uprights which attach differently.

Thank you! Exactly the view I'm looking for. I have an OEM GT4 but was curious how the APM GTS looks like.

Ah gotcha. Yea I was looking at your OEM wing, actually I'd ideally prefer to run the OEM, just need to source another trunk to cut. Any interest in my GT4 with GTS mounts?

Nope, OEM GT4 mounts differently than GTS

I actually am interested. Recently drilled my trunk to install the GTS wing and miss the size of the GT4 wing. Definitely noticed the downforce difference at the track event I did this past weekend. Shoot me a PM and let's work something out.

I’d be interested as well.

I realize I haven’t posted an update in awhile but I did finally get the GT4 splitter on, better pics to come when the rain stops. But during this time I also swapped wings with @ENDL3SS and have been working on installing the OEM GT4 wing on a replacement trunk, and just wrapped that up this weekend!

In some cases, more than one!
