I just installed Energy suspensions bushings front and rear and also a set of Koni dual adjustable coilovers i valved by True choice. They have 7" 500/400 spring rates.

I set the ride height to 4"all 4 corners measuring ground to jacking points at wheels.

Local garages will only do factory spec's but if i give them the numbers they may plug in what i want. Suggestions?

This is track car not a daily driver. I run TTC with Nasa with it.
