QA1 gen F coil over conversion for custom spring rates

[79 Z28]

im sure everyone knows about the QA1 coilover kit for the 4th gen f bodies, they come in 2 flavours. the road strut and the drag strut. i was doing some research and called QA1 with my issue in making a handling solution out of the coilover kit they supply. as they only offer 3 spring rates which are all soft.

275# drag
300# mix
325# which they call their handling ones.
all rates are linear.

i just got off the phone with their tech guy and he informed me there is a conversion for the gen f strut they offer for our cars that allows you to use a std. 2.5" ID 12" spring with a conventional spring retainer on the top. as the kit origionally uses the factory perch which is smaller, not allowing a std coilover spring to fit, limiting you origionally to the 3 choices provided. this conversion now allows you to use and customize exactly what spring rate you wish to run in the front now.

new part numbers are:

SS112SDM - the gen f conversion mount for the coil over to use std. coils
9018-101 - the upper spring cap

then you can order any 2.5" ID 12" coil spring to fit your needs in spring rate. available in 25lb/in increments up to 600 lb/in now and have a 12 way adj. system with full ride height adjustability now with some real spring rates for handling.

i was thinking about doing the 4 corner coilover, with 500# fronts and 150# rears with the SA 12 ways all around, what do ya guys think?

its not a matter of IF, its gonna be whichever the best system is, just need resaerch. either gonna be konis with custom stranp performance springs, or these, ones adj. the other isnt. they are pretty much the same price. will be around 1400-1500. coilover being a bit less. i just want the better performing one, cost isnt an issue.

must be nice lol. u setting it up for street use? or are u making it a straight line car??

i wish cost wasnt an issue with me, im running sportlines and konis, not 100% sure how thats gonna turn out, but shouldnt be TOO bad for a street car :fingersx:
