just working if these would clear up front. i have 17x8's (+40) now but i have yet to see if there's enough clearance for x9's.

 

They will stick out about 5mm in the front, depending on the tire size they may rub in the rear under full compression. The track wheels in my sig are 17x9 +34 with 255/40s .... click the other pic link for some more shots. With my setup they never hit during normal driving. The rears hit the inner edge of the fender going thru deep dips at 100+mph

 

Yup, Z32 TT rears stick out just a tiny bit up front with -2deg camber at 16*8.5" and I'm pretty sure a 35mm offset. 9" +35 will stick out a bit, not too sightly.
