I followed Clint's recommendation and purchased digressively valved front Bilstein struts. The idea is that they provide more suspension compression/rebound support at lower speeds and less compression/rebound resistance at high speeds so that it absorbs big hits well (freeway expansion joints etc) but does not allow as much body roll through turns. This is a more 'modern' type of setup.

I'm glad to be rid of the torsion bars and also used Clint's progressive rate front springs that Yasin is showing.

Great vid explanation tonger, thank you. I have a feeling I'll be going down a similar path, the advances in shock and spring technology is very hard to resist.

Thank-you! I certainly enjoy driving the car with the coilovers and in my opinion further advances the development of the chassis.

I spoke to Clint regarding reinforcing the [rear] shock towers and in his opinion it was not needed as my car is a '89 and the towers are quite "beefy" from the factory. As a reference Clint has a long hood early 911 that he races and he hasn't reinforced the rear towers on that car. I am also running stock camber plates.

My best,
Yasin
