I am working on the cantilevered coil overs in my head and on the internet. No kit yet to measure from...
A chunk of weight would be shed with losing the strut mount and FFR extension bracket. Some weight would be gained with linkage, but I believe the bell crank ratio can allow for smaller stroke, lighter coil overs which can be mounted low and horizontal.
Im still hopeful that I can find a reasonably priced, ventilated racing spindle to adapt. I reserve the option of designing and casting some. Who has that RP printer?
