I wonder if there are any 997owners who have modded their suspension to - for example - Bilstein Damptronic (PASM compatible), because they track their 997 ?

I would like to hear some experiences on that matter...

Or is it just overkill on a "normal" 997 and should they buy a GT3 ?

I plan on doing more trackdays but don't want to change car, I own a 2006 997S with PCCB, short shifter, sport chrono, ...
