© 1998-2004 Rennsport Systems

Rennsport Systems offers the superb Glen Sander Engineering Torsion Bars made in tubular, gun-drilled styles. These are an excellent upgrade that will have minimal effect on ride quality. This will really go long way in reducing dive, squat, and lateral weight transfer.

Rennsport Systems can offer specific recommendation's for each series of 911/930. Please call for an individual consultation or visit our 911 Performance "Let's Talk about Porsches" pages. 

Tubular Torsion Bars will weigh 25 to 30% less than a solid bar.

Racing applications depend upon tire sizes. Please call for application information
