I'm looking to improve the suspension for my '07 997 Turbo. Several options have been suggested: Bilstein B18 Damptronic, KW Variant 3 plus a couple of others. I want to lower the car approx 15mm, improve the cornering entry and exit speeds without tremdous sacrifice of street ride. (I'm already running 345x20R20's on the rear). I'm wondering if anyone has experience with any of these and would share their thought on:

1. Experience with any systems.
2. Should I preserve PASM or not?

Lastly, I'm considering the EVT700 system from Evolution Motorsports. So, the suspension should be able to handle this kind of power.

Thanks and I look forward to your advice.

 

The latest copy of Excellence magazine has an article on the EVT700 with some comments on suspension. You might want to check it out if you haven't done so already.

 

I would recommend using the Bilstein PSS coillover system which keeps the PASM. I have installed quite a few units now, and they have been great. A few of them have been on Evo700 kits, and they handle great even with the power. Around town it is still very nice and compliant, not too harsh, but once you hit sport mode, it becomes quite stiff, and you will find yourself only using that setting on the track for the most part.
