You can also look into Ruf's springs... I looked into them a while back and was told they are a different rate than the H&R. On the 3400s and 3600s, ruf's only suspension modification to the boxster are their springs, they dont offer coilovers... which I thought was interesting.

 

TehcArt springs are manufactured but Eibach but at a different factory in Germany and they have a slighlty different design. The TechArt springs drop is a little bit more aggressive and probably different spring rate than the standard Eibach. I think they are just engineered to a higher standard. I have have H & R before on a VW and had no problems but I have also had a few friends with H & R who have had the rears sag a bit and a M3 and on a Benz C55. When I purchase my Cayman S next month I plan going with TechArt suspension just because I believe that TechArt as a great P car tuner and they have been around for a while so I'm sure their customer service and support is outstanding.

 

But they don't have alignment equipment.

 

Does anyone have any pics of their cars with the H&Rs? I want to lower my car about an inch, but not drop it as far as the Techarts.

I'm also a chicken-**** about screwing with the M030 suspension on the car, which I love....but like I said, it needs to drop an inch or so.
