Wheels aren't in yet...
I opted to go with Arc-8 compatible version, because I am "trying" to prevent tramlining with 9.5 inch setup as opposed to the 10's you will find for apex's direct fitment.
275/40zr 19 on 9.5 rims x 19' @ 22 ET square 4. I have the oem LS 18s' so it should be 1/8 inch inbound and 7/8 outbound. exact same heigt/dia. They will prbably just square with the front fender. But- these are more square of a profile so it will appear aggressive. OK pop quiz.... as ANYBODY ever paid $114 each for gm TPMS????? I stopped at the dealer figured to save a few mouse clicks... learned my lesson..... I will circle back to apex, for adapter rings and tpms. their website was having problems. I bought from bimmer world for free shipping... Yes same bolt up as bmw.
the nittos came in at $150 each with a flash sale at discounttiredirect.com
heres what I used to research..
