I just bought a set of four BF-Goodrich KDW-ZR tires from The Tire Rack (TireRack.com) and lo and behold a day after the tires arrived I got a certificate in the mail for a FREE (thats' spelled F-R-E-E) G-Tech "Performance Measuring Device" or whatever you want to call it. The promotion is only if you buy four tires and I think it expires like September 30th or something. I saw that some of you fellow SSers' were skeptical about the G-Tech's performance and while I do not vouch for it since I have not received my free one yet, here might be a good opportunity to get a free one and try it for yourself................besides you know your Super Sport's tires are shot from all the holeshots and exit ramps at 90 m.p.h. anyway!!!!!!!!!!!!!!!!!!!!!
