i have some freshly ordered 215-50-13's with 5005 date codes that I could swear aren't any faster than the almost worn out 4205 date codes they replace. the new tires are less prone to go greasy as expected, but don't seem to offer any more grip, which would make them less grippy when new than the old set was when new......
WTB: CSP Spyder parts. What you got?
