I tried a search, but came up empty handed with my specific question. I know alot of people on here are running a Pro-Kit, so what has been the tallest tire you have been able to run? How about widest? Rolling the fender lip and clearence by the lca included.

 

I'm not sure what ya mean by Pro-Kit but I'll assume rear springs/suspension set up. I'm also assuming you mean racing tires and not street radials.

I have stock rear springs w/airbags and fit either 26x11.5x16 ET Streets or 28x10x16 Hoosier slicks on stock GTA wheels without modification.Next year I'll be trying either 28x11.5x16 ET Streets or 28x12.5x16 ET Streets on stock wheels and see what has to be done to get them to fit.

I know of others who run wider 15" rims with different backspacings but I stick to the stock rims and surprising people with wheels up launches with stock wheels all around

HTH,

By Pro-Kit I meant the Eibach Pro-Kit, supposed to be a 1" drop. I know that ive seen people running 26" tall slicks with fair clearance, but I was looking more along the line of being able to run a 27.9" BFG drag radials, 325/50/15.

 

I used to run a 265/50R16 BFG on a stock IROC wheel, and they only needed minor hammer clearancing on the lower inside of the wheel well....
