Just gimme some traction!

Posted on

Kevin brought his pro-built ’32 Roadster to us to solve a traction issue.

He had the car built a few years back by another shop here in town. When they set up the car they used common street rod parts but set them up at a ride height they were not intended to be used at. The rear was set up with a triangulated four link and Aldan coil overs. Even with sticky slicks, he couldn’t get decent 60′ times due to the tires dancing and skipping around.

We set the car up on the rack and started measuring things and found he had -65% anti-squat! It’s a wonder he could drag race this car at all. We even tried doing a smokey burn out but could barely leave black marks on the pavement. Notice the exhaust getting pinched between the lower bar and the frame.

We discussed our options and Kevin decided to ditch the under car exhaust for a cone/lakes header arrangement and that freed up the under side for our favorite, the torque arm. I crunched some numbers and determined we needed to shorten the rear links and also raise them about 2″ from their original mounts. With the 39″ long fabricated torque arm and new lower mounts (plus a new panhard) we were able to deliver a 138% positive anti-squat!

Kevin took the car out for a test drive and was very pleased at how much more controlled the car felt. The dancing deuce is no more!
