BB E-body street/strip car that runs mid 10s on 275/60R15 DOT drag radials. Had to pull off the k-frame so a local shop can repair the frame damage that is the long-term result of battery acid spillage.

Now that the k-frame's out, I'm considering doing an upper control arm upgrade, a strut rod upgrade, and replacing the lower control arm pivot bushing w/ Delrin stuff. I figure anything that can help free up how well the front end responds coming off the line is a good thing, and it'll never be easer to do than now.

Any suggestions re specific parts that you've had good results with are appreciated. I'm looking at the QA1 non-adjustable upper control arms w/ polyurethane bushings, and a couple of companies have replacement strut rods of different designs. Haven't ordered anything and am open to suggestions.

FWIW, the shop has just put on US Car Tool front fender braces and the car had frame connectors already. They're also installing front & rear torque boxes and a radiator core support. The current front dampers are QA1 R-series which are single-adjustable only for extension resistance and have a very stiff fixed compression setting, and the torsion bars are OEM 318 pieces which are .860" IIRC. Rear suspension is CalTrac bars w/ their split monos and archaic Rancho 5-adjustment truck shocks. The car's best 60 before was a 1.45 on a 10.52 @ 126.5 pass.

Thx - Brad
