Busa SpringsThese Busa springs are the stiffest springs you can buy for the grom clutch! They are so gnarly that you only need three unless you need 6 for the hardest biting clutch possible! You will need a 6 bolt modded pressure plate and lifter spring plate with these springs or your stock 3 bolt plate will break. Sold in sets of 3 springs. Once these sets are gone, they are gone and will not be restocked!
