Update on Sledgehammer...
Just for anyone following along with the evolution of Sledgehammer, we've decided to depart from the stock PASM suspension. I've been having some issues with the car getting "light" under hard acceleration once the car passes 140. With the power the car is making, it would keep the nose up in the air enough to allow the airflow to get under the car and start to generate lift... never a good thing! This effect had been diminished somewhat when running the dampers in Sport mode. However, with the rear squatting so hard under power and the nose staying up the car even started to wander on the 9.7 pass at the dragstrip on the top end (watch the video closely). Since David has asked me to run the car at the Texas mile (and hopefully try for a 200 run), I felt that getting the car to settle down at speed was a prudent move. To that end, we've put together a suspension setup that is giving us the compliance we need for street duty and the stability I was looking for. Basis for this setup is a set of KW's. I've been very happy with the quality of the product. Here are a couple of pics...

About 1.1" front... a little less in the rear. We're currently testing different setups to see what will serve us best in terms of stability and making the car feel more confident over 150 while still maintaining enough room for inconsistent surfaces (i.e. Ohio roads 
).
).

if you read through the thread, you can find the 60 - 130 mph video, as well as the 9.79 second 1/4 mile video as well.

wow!
Read the whole thread, is there a prize for that. Nice car congrats to the owner & to the tuner
I think a page has turned in the porsche world, in short the 997's are looking better.
