Great thread with some good insights. Guess I'm in a slightly different boat as I plan (plans change) on paying up for a more comfortable street option coilover and that's where I think the JRZ shines in my case. Would agree with others that a dramatic difference in lap times probably doesn't exist (although it might) but comfort on the street does. I'm trying to build a true dual performer that can go on road trips and out to dinner and hang with vettes, vipers, gt-r's and gt-3's (not too worried about much else) I believe it's this true dual purpose that costs a premium and that's where I'm looking for value in the set-up... But that's just me...
