My question is would it be possible to have 2 19x8 front 20mm offset and 2 20x10 25mm offset in the rear. Do you think it would run in to problems performance wise or treading wise and of course would it work. Thanks

 

I shouldn't be a problem. We run the SCCA T-2 setup with 9" fronts and 10" rears. Also a 285 x 18 Kumho tire. Works fine, set the lap record at Roebling weekend before last.

20" wheels wont give you a very comfortable ride though.

 

Of course it will work. You can put 17, 18, 19 or 20 inch wheels on any axle in any combination.

 

As long as they are the same left-to-right, you will be fine.

If it makes you feel better, Ferrari staggers their wheel sizes (both width and diameter). The 599GTB has 19" front and 20" rear wheels.

 

You are welcome.
