Upper control arms for drag racing 78 T/A
I ended up buying a set of BMR Suspension lower control arms for my 78 T/A as it looks like we will have a heads up series for next year. My car is pulling the front wheels up on motor and Hoosier QTP tires and next year I'll be running full slicks and occasional nitrous. With that said, years ago I bought a set of Speedway motors 9.25 inch (stock length) upper control arms for the car. My goal of course is dead straight for drag racing. Do you think stock length will be adequate for that or would I need longer or shorter upper control arms?

Stock length are fine. Plenty of people are hauling ass with factory control arms.
I had TRZ uppers on my car, but they limited travel, so I went back to my factory uppers. Double adjustable shocks are game changers, if you're looking to upgrade your front suspension. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
