Starting to think about wheels and want to make sure I get the right ones...

 

Corey,
front: 8 J x 18 ET 50

rear: 10 J x 18 ET 65

 

I should also ask, what are the offsets for GT3 wheels 8Jx18 and 11Jx18

 

GT3 style wheel for TT & C4S:
front: 8 J x 18 ET 50

rear: 11 J x 18 ET 45

GT3 style wheel for GT2:
front: 8.5 J x 18 ET 40

rear: 12 J x 18 ET 45

the true GT3 wheel:
front: 8.5 J x 18 ET 40

rear: 11 J x 18 ET 63

 

so 40 and 63 on a Narrow body...

So with the 5mm GT3 spacers the effective would be 35 and 58 or 45 and 68. I'm not sure exactly how offsets are measured...

 

the smaller the number the more aggressive the wheel is therefore if u add 5mm spacer on 40/63 it'll be 35/58 after. on a narrow body C2 u don't want to go beyond 40/63. remember the front wheel for GT3 wheel is 8.5'' wide compare to the rest & using 235/40 instead of 225/40 tire (so does the rear 11''). the width of the wheel is as important as the offset. u need to know both number before making ur decision.
