Just bought a set of niche circuit black/ machined staggered fitment front 20 x 8.5 with 35 offset , rear 20 x 10 with 40 offset 5 x120 bolt pattern that were mounted on 2011 coupe and will be mounting them on a 2008 cts4 . Now I have second thoughts on the fitment but I am pretty sure I'm alright. Anyone know for sure or do I just have to wait until they arrive to find out the real answer.
The fitment should be fine but with the staggered setup on an all wheel drive car can through off the drive train. Ive read some posts were people have done it and been okay but others have had problems.
Not too worried about the staggered because I have a one ton dually pickup 4wd which has double the width of tire on the rear that has no issues driving when 4wd is engaged. As long as diameter match front and back I should be O .K.
I checked a tire calculator online and a 245/40 /20 has a diameter of 27.7 and a circumference of 87.1. A 275/35/20 dia is 27.6 and cir is 86.6 which equals to a -0.5% . I checked out a cts v tires and they come in at a -0.7% . So with all this said I " think " the staggered is ok since I've seen guys running the v wheels on awd cts. But then thinking don't compare to the real deal either so I'll have to wait to find out for sure.
