Default Wheel fitment

Hi yall. New C4 owner here.I i love my car, I wish my wheel combo was squared. 18s in the back and 17s in the front. The front wheel well has so much of a gap between the tire and the fender. Also front wheel looks so tucked in. Id really like it to be flush with the fender + fill in the gap, so to speak. I see other peoples C4s with stock wheels and theyre exactly what i want with the flush and no gaps. Advice? Google says 18" x 9.5 all around is ok. Wont cause rubbing or speedometer issue. I take it the c5 z06 wheels only come in 17s? Because i cant find 18s anywhere.

I don't know anything about 18 inch wheels but 17x9.5 replica A molds with 285 width tires brought my front tires flush with the fenders on the front. As for the gap around it, this is fixed with lowering the front end which is a somewhat involved process modifying the blocks that the leaf spring sits on. On the rear it's just lowering bolts to drop the rear end.

I have 17x11 on the rear with 315 tire and the tire comes out 1/4 inch out the wheel well. Looks really sharp in person. I lowered the rear end about 1 to 1 1/4 inch just to level out the car and remove the factory "rake". did it with a full tank of gas to avoid having the blown rear suspension look.

OP, your car is fitted with C5 wheels. They a bit too much offset up front and a lot too much in back, which is why they look tucked in. You can fit up to 11 rim widths with 50mm offset front and rear. OE Wheels has a number of inexpensive options that are 18x10.5 et56 and will fit your car well with 275/35/ or 285/35/18 tires. I'd go for the latter size since you want to minimize the gap to the fender.
