I just purchased weld 15x8 draglites with 5.5 in. backspacing on them. Will I need to grind my calipers on my 94lt1 or will they fit fine?

 

From my experience, both the Draglites and the Pro-Stars require grinding of the fins on the rear brake caliper. Its not an issue of wheel width or backspacing, because the interference is right at the "knuckle" where the center disc rolls over to become the rim.

 

these are 15x8's though not bigger...not sure if it matters or not. Also what tools to i need to grind the calipers down?

 

Like I said, the interference is near the center of the wheel, not at the outer edges, so it doesn't matter how wide they are. The corner of the fins - the part stick out toward the outside of the car - rubs on the radius where the center hub disc becomes the horizontal "rim".

I started with a Dremel and quickly realized I didn't have enough years left in my life to grind them down far enough, and I switch to an air powered die grinder and a fairly rough stone. I found that if you put a magic marker strip around that radius, you can see exactly where its rubbing and grind the fins only where needed.

 

I just used a regular grinder and started grinding.

 

Well the guy was running an ls1 and the calipers on those are larger so he had to do it but arent the calipers on the lt1's smaller? So do you think i could get away with not having to do it?

 

So I guess our nail file idea is out of the question, Ryan.

 

Only draglites that do not require grinding are the XPs.

 

Yeah Ryan looks like we gotta grind the calipers down slightly. I was optimistic at first but once I put the lugnuts on semi-tight it started rubbing very slightly. It shouldn't take more than a half hour total though. Call my cell so we can get your beast on the track tonite w/ these new skins.
