Default Drag Radials

im looking at mt drag radials but they dont have the exact right size the closest they have is about an inch smaller in diameter how much will that affect my final drive ratio? and ill probably have to make sure traction control is off while im using them

I run 255/60/16 d/r's on my impala. My 60" and 1/8 mile improved, but I didn't gain anything at the top end. These tires are 26" tall if you can find some that are closer to 28" tall you should be in good shape.

16's wont fit on a GXP the brake rotors are too big, 17" is the smallest you can go, without changing the rotors. i wonder if you can use the rear rotors up front since they are smaller

Rotor swap wont work as you still have the caliper and mounting bracket to contend with. Changing the rotor wont change the height of the caliper. You'd need to swap it all out. Maybe brakes from an 05 GP would work but you'll loose a bunch of stopping power.

255 50 16 Mickey Thompson E/T Street radials here. They are pretty good to drive on and hold up at the track.

ya i was looking at the brakes today and the front caliper is way to big for the rear rotor..
Would we have to swap anything else over other then just caliper and rotor from a normal GP? like hoses or mounting brakets?

You'd need the caliper, bracket and steering knuckle I believe. Hoses can stay.
