I have an '06 Carrera S (sport package and PASM). I'd like to lower the ride height down to the level of a GT3 - I think about 25mm. Any thoughts on the best equipment to do this that won't screw up PASM? Any thoughts on how badly the ride might deteriorate? Thanks

 

You can either using lowering springs designed to be used with PASM, or go to a Bilstein PSS PASM coilover system. Obviously the springs are the cheaper route, but in the long run, they will wear out your shocks faster. The coilover system is going to be quite a bit more, but you do it once and you are done, plus you can set the height wherever you want it, where as with lowering springs you are limited to whatever drop the springs give you (usually 1-1.5").

 

Doc if using H&R springs that lower the ride height 1" will you need to have the front end re adjusted for the drop ( my ? is on like the C4S model )

 

Yes sir.
