i'm not road racing, but i wanted a complete system...I heard its a pain in the ass to cut the spring perch off the Koni for the coilovers, and that someshops won't do it.
Also heard that people have to get the coilover welded onto the strut?
Getting the complete system from Leda might be a better deal, after all the labor on the Koni's and groundcontrols
Do you know of a place that sells the Leda kit?
