Ok, so i want to purchase some Work Emotion CR Kai wheels. Is it best to order the custom offset +35 that they dont normaly produce them in, or will the +42 offset fit just as well?

What size wheel?

go with the 35.
42 is for subaru's. 42's will look absolutely terrible on a tC.
42 is only worth it if the wheel is 9.5 inches wide.

Thanks HKSpeed.

The wheel size would be 18"x7.5"

get 35 offset.

don't want to start another thread but ....
18x8 w/ 35 offset will i have problems with Tein SS-P all the way down???

what about a 18x9.5 35 offset for the rear.....?? possible???
