What year b-body? 68-up have huge rear wheel wells, no need to tub. Just move your springs in and roll. You can get an 11/5-12" slick w/o even moving the springs in. Probably 14" w/ the springs moved.
i wish that were true...
70 plymouths have a much smaller wheel well than the 68-9's. with only rolled fenders, herb gets a 315/50 under his gtx. might even be a 325, i don't remember. i have spend a good deal of time trying to get more than a 275/60 under mine. will work fine, if the car never moves from side to side...
anyway, that kit looks interesting!
