Drag Racing Tech - What mods to fit a 275-60-15?

Hey guys I just got my 15X10- 7.5"BS Weld prostars and also got some BFG Drag radials, size 275-60-15. I was just wondering what mods I will have to do? I already see I will have to trim the bump stops. Will I have to use the BFH mod on the inner fender? will I have to massage the frender lip?

Just finished mine up last weekend, it was "fun" :) Things I had to do:

Grinded the calipers like hell. You'll think you have enough, but you won't. It's a long boring trial and error...lots of errors

Unbolted the bump stop, then grinded off the "bracket" for it. Make sure there aren't any sharp edges for one, and make sure you grind as much as you can so the tires won't touch it when you lower the car

Had to hammer the lower fender lip, the one closer to the front of the car. This only took about a minute for each side, wasn't as big a deal as I thought it would be

It took me a few hours to get them to work, but it's worth it in the end. I didn't take any pictures of what the area looked like once I was done grinding/hammering, but there should be some on search

Thanks for the info!!

other than normal stuff like grinding calipers to fit the wheel, i did nothing to make those tires fit my TA. wheelwell area is fine. even left the bump stops!

I have also ran that size tire in a M/T drag radial. I did no modifications either becuase of the tire. I only grinded the calipers to fit the 15" rim size.

You are runnin 11.5 inch wide tires.. He is running a 275/60 which is only 10inches wide in most cases. There should be zero grinding of the bump stops or pounding of the wheel wells to get those tires under an fbody.

I figured they were the same size, my mistake :)
