I sold my SS and no longer need these. The Progress bar was on the car for about 6 months, I then purchased the Torque Forward bar and modified the Progress bar so I could run both. This setup helps torsional stiffness as well as deflection. It was a killer setup on the auto-x track and allowed me to dial-in some preload into the suspension. I'm asking $150 for the dual bar setup plus shipping. Please let me know if you have any questions.

 

how does this bolt on to the car?

 

interested, but need more info

This bolts up the same as all Progress Bars, I believe there is a how-to on this board for it.

Basically it uses two factory holes on either side of the rear beam, the above pictured bracket slides into the beam and the bolt goes through the existing hole into the bracket. Install time is roughly 20 minutes.
