I am looking to have a set of H&R lowering springs installed in my 06 4S. I know that it is more then just a spring swap out job due to my car being ALL wheel drive and the electronics from the PASM. I am looking for a local tuner who has done this before, and has a good reputation. Any suggestions?

 

If you want a good suspension specialist you could use tony @ TC Design in Milpitas. I'm usually not keen on the H&R springs;( Unfortunately the ride isn't very compliant with that set up and it tends to sag over time;( We've actually taken off a lot of H&R spring set ups. If it's not too late try an Eibach or TechArt set up.

 

Go with a set of coil-overs you will not regret it. I would never install just a set of lowering springs - it ruins the ride of the car IMO.

 

Roger Kraus Racing in Castro Valley (it's on Grove Way, I think). I've only heard (from SCCA friends) that they do fine alignment work - they also do suspensions as well. You could always ask their opinion for a data point (I think they've worked on the Lizards cars so I suppose they have experience with Porsche brands).
