was wonderin if anyone knows if its possible to have 20x11 in the front and 20x13 in the rear. I would like to run the Michelin PS2 275/35/20 and 335/30/20. Can anyone help me out with the right offset I would need to make it clear without rubbing? I called CCW for the size before I order but the gentlemen gave me some weird offset #s that my local race store said wouldnt fit like 40 in front and 56 in rear?

Wheel Offsets

The Factory offsets are like 40 and 59. This is the mm from center the wheel is. A 13 inch rim is really 14 inches wide - outside measurement. By moving the center in 3 mm (56 mm) but increasing the rim by one inch (25 mm) it is effectively putting the very outside of the rim outward 9.5 mm and inward 15.5 mm from what you have now. The Z-06 is like 1/2 inch (12 mm) inside from tire to outside body so this means the tire would jsut be flush or slightly in from the body line.

If you have any questions you can email me I had this hole thing with the HRE's I got.

thinking about going to an hre set up now since I hear rumors that ccw offsets rub. Can anyone confirm that a 20x10 offset 59 in front and 20x12.5 offset 43 in rear will fit the c6 z06? And would this 59 offset also apply if I ran a 19x10 in front. Also anyone run the 20x11 or 19x11 in front yet? Or a 13 in the rear without rubbing?

Help with offset for 2007 c6Z06 Wheels

For sure 20x 10 59 offset will hit or rub in front maybe not strait but when turning and if car is leaning a littie in a turn. Backs are no problem because wheel stays pertty much true . 19x10 59 offset you mit be able to get away with . It might be better with 19x 81/2s in front if HRE makes them or any one els. wwc rub I know this guy that has them he is not to happy with them.:partyon:
