Kings lows are the same as FE2 which is what you would have in the Clubsport.
The superlows would be the way to go if you just want to go a little lower. Be sure you have the shocks to suit the FE2 otherwise it will be the same height anyways.
Hope this helps.
my cat is 71mm off the ground at the moment. i need to know so i can decide on new springs. either supers or ultras. i dont want to lift it too much, coz i like it slammed, but its a defect as it is.
oh ok, wen i got my supers i got my exhuast lifted for 50 bux, is your exhaust high as it can go? if so ultras should be fine, but then again i got supers and im only 12mm over the limit.. yours should still look good with supers any way
