Should you not agree with our choices of spring rates on our own 'packaged' Variant 2 and Variant 3 KW's, feel free to contact us to get a custom set of your own... Our packaged V2's and V3's are designed with the daily driver/track rat in mind - meaning that you can kill it at the track, and yet still maintain functioning kidneys if you drive it on the street. Are they optimized for the track? Yes, actually, KW met Dr. Mike at the track with their 18 wheeler and they tuned-and-tested-and-tuned until they got what Dr. Mike wanted, all the while scaring the bejeezus out of the KW lead engineer (who puked, I believe, at least once). Are they optimal for a race car? No. But, let's face it, nobody really likes to blood in their pee, do they? And how many people can really say that they "Don't care how their car rides on the street because it's just for the track, anyway, and I gotta have insane spring rates"? Our already-spec'd units are in stock and maintain your urinary health and meet 99.99% of a track junky's needs. But, if you're in that 0.01% that need something different - give us a call. We've shipped a couple of completely custom sets already, with more in the works - mainly to people that either don't daily drive their MINI or don't have/like functioning kidneys.
