Why to NOT lower PASM cars
I was looking into options to enhance the track performance of my 997S. I asked Farnbacher Loles about lowering springs, PSS9s for PASM, GT3 Cup control arms for more camber, etc.
I heard of PASM failures before when people used lowering springs and was very interested when FBL wrote about my 997S with PASM:
I do not recommend the lowering springs, as the oem shocks are not valved for the shortened spring and will blow out over time.
Thought the collective would be interested in this opinion...

I suppose it is, but so many 997S owners are buying lowering springs that are supposedly "for PASM" and I thought they might benefit from this opinion. I don't know enough about suspensions to know if it applied to PASM cars vs. other cars...

There are some reports about broken struts after lowering. But if it's only the new springs fault is or some other reason isn't totally confirmed. However, the the suspension travel is reduced when lowering, so you will get a higher tension on a smaller area than original.
My car is now lowered with Techart's with 15mm. Since my car is moderate lowered I think the tension is less than if I mounted the H&R with 25 mm. Anyway, my garantee expire the end of this month, and either way when the suspension is finished I will install the PASM compatible PSS9.

this topic has been discussed ad nauseum on this and other boards. tracking your car will wear out the OEM suspension faster than road use too. Does that mean you shouldnt track or AX? iOne or two posts of people with blown shocks isnt an accurate representation of outcome from lowering with aftermarket springs. I have several friends who track and AX that have screwed up their stock suspensions long before they should have gone out. solution....new coilovers. not trying to be argumentative, but it seems like this keeps coming up.
if you dont want to drop....dont do it. modding sometimes requires taking risks.
