H&R Race Springs on ZHP

An underdamped damper cannot dampen the high frequency of a high spring rate...That being said, BreakMyWallet, if you take your friends car to a race track, it will not perform nearly as well as a set of matched damper/springs...I think you know that, it's just not really something that needs to be bought unless you feel you're going to get everything you can out of the bilsteins etc...

I can speak from past experience on this one...I had installed lowering springs on stock dampers for another vehicle...Holy crap, the OE dampers couldn't dampen the oscillations in the spring worth a dam

very well put. i was just making the point of making the handling of the car worse

my race springs and zhp shocks felt amazing, was even better when i replaced my rear shocks with bilstein sports. sadly that was around the same time the fronts started going out as well

Hell, I think I want to trade somebody my sports for races...I just want a bit more of a drop

LOL, yea my zhp suspension was showing serious signs of performance depletion after 60k.
