hi my friend, fd seldom get lower spring,most is adj8ustable
if u wan comfortable pls use 99spec original (yellow colour bilsten with blue colour spring), bcos now i am using it, is very low and comfortable.
Nothing to do try to do some research online but seem a bit blur here.
Let say if we have K3VETT with 1 ori IHI RHF4 turbine for pickup and another with bigger size for end power, what will be the advantage...
