Im going to be ordering 19s or 20s for my coupe soon.. I was thinking maybe 10.5-12in wide in the rear.. please post some pics of how wide you guys are going width on your coupes...thx

 

most of coupe owners go with 10.5

 

Anything over 10.5" will rub if you car is dropped, so you will have to first roll the fenders and or raise the car. I am running Tein Flex with a 3/4" drop and 11" rear and I still scrape in hard dips on the road, with the fenders rolled.

10.5 rear

 

Avoid the any future headaches and perhaps some additional mod costs . . . Go with the 10.5".

 

10.5 is what I have and I wouldn't go any wider... like everyone said, it will most likely rub on the fenders or hit the suspension if you go any wider. Even if you can fit such wide wheels, then you have a problem of getting correct tire sizes to work with VDC as 275 on 10.5" wide wheels already look stretched...
