Rear Coilover Spring Rate Help - Page 2

Mike Rietow · 05-30-2021, 03:10 AM

I bought a set of D/A Koni's Bickle valved in the late 90's. He suggested a 175 on this all steel Nova.

If you look at his spring recommendations in one of his catalogs, 1500-1800 rear weight he suggests a 175.

I did put a 125 spring on this to run some local 370 Pro Tree races. It did work for the fast tree, however it acted more so than previously, like it needed a ARB. Ladder bar sbc 10x28 bias, 3200 lbs.

Eibach or PAC coilover springs are the good ones, if you can find PAC, they've stopped producing , coil springs.

I just bolted a set of PAC 165 on this, i bought and made one hit on in 2017, went 1.28 60ft last car down on a Thursday night test n Tune prep n/a sbc. 1550 lbs on back tires.

Not criticizing anyone's suggestions here, just stating my experience, light vs heavy spring.

OP stated he was using a 19" shock. I made some assumptions from that as far as shock travel, installed length at ride height, spring free length and compressed length at ride height, etc. All of which make a difference.
