I don't know that Centerline makes a 15x10 Telstar in the required 7.5" backspace...They do make a 15x8 with a 5.5" that will work...The 15x4s will work, too...I don't think theres any grinding/mods to fit on LT1s (smaller brakes), but I don't know about LS1s...Do a search on here and cz28.com, too there are some guys that run them..I think MagnumV8 on camaroz28.com has them...

I run 15x4 front and 15x8 in the rear. Back spacing is 5. Lt1's reguire little to no grinding. On a LS1 the fronts take a little grinding. The backs take alot of grinding.

They do make a 5.5" backpace also in response to the GMHTP car a few years ago..Just tucks them under a wee bit more...

I have 15x10s on mine but I have my rear narrowed 4 inches over all, they dont make the right offset for a standard width rear, you can only go with a 15x8, I just picked up a second set for my car this week.

I've got them on my car, and I've converted to LS1 front brakes.
I had to use spacers in the front for the 15x4's.

In the rear, they fit fine with LT1 rear brakes.
They don't fit on the LS1's without massive grinding to the
calipers in the rear.
