315 or 325 MT Drag Radial? Getting ready to order up a set of drag radials for my build and I cant decide on the 315 or 325 M/T drag radial. They will be going on my 93 RX7 plans are a 4-link, solid axle and a mini tub. To go with the powerglide and single turbo setup. Sense I will be going with a Fab9 rearend I will have all the gear choice options so I can setup for a 28" or 30" tire. What do you guys reccomend, Mickey Thompson tech says go with the 315 for the extra sidewall flex and the extra .4" of tread width. Below are the specs on the tires.
325/50/15:
Tire Diameter 28.00 in.
Section Width 13.10 in.
Tread Width 11.60 in.
Weight 37 bs.
315/60/15:
Tire Diameter 30.00 in.
Section Width 12.90 in.
Tread Width 11.90 in
Weight 39 bs.
325/50/15:
Tire Diameter 28.00 in.
Section Width 13.10 in.
Tread Width 11.60 in.
Weight 37 bs.
315/60/15:
Tire Diameter 30.00 in.
Section Width 12.90 in.
Tread Width 11.90 in
Weight 39 bs.

I am leaning towards the 315 radial. Here is a picture of Brain Hinson RX7. It has a Twin turbo 402ci LS1 w/powerglide and is back halved with ladder bars and a 9". He is running the 315/60/15 and 4.11's.
