I was wondering which would increase straight line traction more? I am looking at the the Spohn torque arm and the Spohn drag rear sway bar. Any opinions? Thanks

 

I'm not familiar with Spohns drag sway bar, an adj torque arm is critical for setting pinion angle...I'm goin to get the Spohn unit very soon....Pinion angle is critical for traction...on a street car 2 degrees negative in relation to the driveshaft is usually good and wont harm the U joints...

If you have to make a priority choice, IMHO, go w/ the TA first.. I have the Spohn adjustable TA and it is awesome. Hope this helps!

 

TQ arm!!

 

Torque arm for sure. The rear bar will help keep the car level on launches.
