Torsion bar replacement with age
Interesting Q&A in the new 911 & Porsche World magazine. A 95 CS owner with 107K miles who tracks the car notes that one side of the car sits lower. Peter Tognola, who owns a service and track prep company, replies
'This is a common problem with 968 models as they reach this age. It is caused by stretch in the rear torsion bars. The rear ride height can be adjusted on the spring-plate arms connecting the torsion bars. However, to restore the suspension to its correct performance, it is advisable to renew both the rear torsion bars, plus the suspension bushes and the shock absorbers-a substantial job.'
Anyone here have issues with aged torsion bars?

i've seen a couple 968's with a sagging rear suspension, even after rebuilding the shocks. thought the torsion bars may be a problem. The above quote confirms that.

Porsche made the car sit higher on the driver side, so when the driver gets in, the car levels out. Could this be the same discrepancy the mag referred to?
