Can anyone tell me what my options is for rim size on a stock 93 gt with five lug conversion?  will 18x9 fit on the front and 18x10 on the back without rubbing like on the 94-98?  what is the largest wheel and tire combo i can put on it with out looking like a wagon wheel.

The wheel hub on the 94-98 is bigger than the 93, I have a 90gt with 15x10 prostars, an a 28x12.5, I had to pound in the and roll the inner fender well.  On my 98 cobra I have 18x9 in the front with 275, and 18x10 with 295's no rubbing and no mod to the fender. These are saleen wheels, no sure of back spacing, that will make a difference, the back spacing on the prostars, 6.5

hope this helps.

17x9 with a 24mm offset all around is a real good fit
