Offset Question, Please Help
I will be purchasing wheels shortly and was wondering, which offsets would be best for a 2007 C6 Corvette? I am doing 19x9 F and 20x10.5 R. I would like all wheels sitting flush w/ fenders. Thanks in advance.

Its pretty simple the .5" wider wheel with the same 79mm stock offset will put exactly .25" inner and .25" outer. OE Concepts wheel has that wheel with a 75mm offset which adds another 4mm over stock for a total of 10mm (including the extra .25" of the new wheel) 10mm is just shy of a half inch. If you are going with a narrow tire, in other words the side wall goes straight up or bow in go with a 75-76mm if you are going with a wider tire that bows out a little stick with the 79mm. Hope that helps.

No No, I am sorry I thought you were talking about the just the rear, the front is the same formula though. Stock is 56mm and your adding a quarter inch inside and out, so if you want more than a quarter inch you can take off a few mm down to 54 - 52mm. 52mm with put you 10mm over the stock wheel, once again just shy of half an inch. To me it really depends on the width of tire you go with.
