Actually Knight's correct but has his terminology wrong. The PSS10's afaik have tenders, not helpers so the smaller springs are not fully compressed. You need to use the equation (axb)/(a+b) = spring rate.

 

Hey guys,

Just thought I'd follow up on my original so that the thread is properly closed.

I lowered my tire pressure and it did make the ride better. I also took a test drive in another Rennlister's TT w/ stock setup and driving both cars back to back, we could not see a significant different in ride quality (if any)..as a result, while I still think that the ride is a tiny bit on the harsh side, I elected not to change anything at this time.

I hope to have an opportunity to drive a TT w/ PSS10...only then will I decide whether to buy them or not

Cheers,

Olivier

 

Slicer, you beat me to it on the purpose of helper springs on higher-end Coil-over systems....ok, at least on my KW's the smaller springs are compressed...maybe the PS systems are different. I have KW V3's on a medium setting and I would say they are not harsh at all. We also have a 997s(wife's car) and with the sport button pushed I'd say the ride is actually more harsh than the V3's(on mid settings).

I have not heard a bad thing about PSS10's and would say if you have the funds going in that direction is worth it.
