any body know what size o.e zo6 rear wheels are.9.5 or 10.5,will a 10.5 on a 295/35/18 fit on a 4th gen with out modify.thanks

 

the 295 tire you list will have a diameter of 26.1"....stock is 25.7" so it will be slightly bigger, not enough to throw your speedo off though. it should result in less about 1-1.5mph variation (speedo reading slower than what you're going).

the 10.5" rim will fit fine on the rear of a camaro...you may have to grind down the bump stop. i'm currently looking for before/after pics of that since i'm putting 315s on my car soon. i'll try to post back if i find anything

 

the stock zo6 rear wheels are 10.5. Had to modify my inner tire well with a hammer and grind the jounce (sp) bumpers to clear 295/35/18 tires . Now the car needs to be lowered about 1.5 inch to look better, which will probably open another can of worms

 

do a search for injuneer. He's got details and good pictures for wider 11 inch zr-1s install
