Lower Offset Rear Wheels

[Driver_WT]

I am looking at a set of wheels for the C8. The rear wheels are stock size (20 by 11), but the offset is +45 mm versus +64 for stock. So the rear wheels will stick out 19 mm or 0.75" more than stock. I see others running wheels with less offset - is a 19 mm decrease in rear offset workable. I will also be running stock tire sizes.

Front wheels for the same set are stock size (19 by 8.5), but with +45 mm offset versus +52 mm for stock wheels, so I am assuming that a 7 mm change in front offset won's cause any issues.

Thanks.

i speak to a wheel dealer and they said to me 35mm will be flush or near the car fender

Thanks, sounds like 45 mm offset front and rear for stock width tires and wheels should work.

I went 35mm front and 45mm rears. Waiting till spring to put them on the car.

That looks like quite an aggressive spec with the increase in width and decrease in offset. Looks like you will be moving the outer edge of the front wheel out by 23 mm and you will be moving the outer edge of the rear wheel out by 32 mm. Do you plan to run the stock camber settings or are you going to more negative camber? Do you have confirmation that these specs will work without the tires rubbing? Should look awesome.
