Are JRZ/Moton/whatever actually faster than the track oriented KW's, and if so, is it a difference that a normal track driver can appreciate, as opposed to a .2 second benefit that only a handful of even experienced drivers can appreciate?
I don't think you'll ever find that information unless some magazine does a comparison test.

I like JamesClay's discussion. He should stop f'ing with his projects and talk to us. We're more fun. But his people that answer the phone are pretty knowledgable about a handful of products, pretty straight forward people. I talked to them for awhile about my E46. They did throw the JRZ thing in my face but we mostly talked about the TC Kline S/D vrs AST 4200s vrs Ground Control. In the case of my E46, I didn't even consider the KWs because they have strut tube to wheel clearance issues on the non-Ms. Won't allow the fitment of 255s on the front. KWs should be in the discussion for an E9X M3 though.

I think Bimmerworld has Turner beat in the coilover department because Turner's selection seems somewhat limited (that is my opinion). But I'm sure Turner can provide some expert insight as well. I believe Turner is starting to get some factory support for their racing program? If true, that may give Turner some extra insight into the chassis and suspension design. Bottom line...talk to some good vendors (Bimmerworld, Turner) who use the product in your projected applications (street, track, auto-x) and then try to ride in the car with a similar setup.
