hey,
just my 2 cents, before buying shoes and springs, check your track where you will be racing, how's the bite over there??? no need to get all aluminim and 1.1 springs when the track is dusty and very loose, you will be spinning your wheels without much forword bite!! i would start with a mild set-up, lets say 2 aluminum and one carbon shoes and 0.9 springs and go from there.
why not using the stock xray clutch??
cheers
