Correct spring rate for QA1 coilovers

dragbaron said

I recently got back into the A-body game with another Scamp. It has a 4-link rear and tubular upper and lower control arms on the front with QA1 coilovers all around. The rear rides good, however the front hits very hard over sharp bumps. I've noticed that there doesn't seem to be very much gap between the front spring coils, and I'm thinking the spring itself is "bottoming out". I have no idea what spring rate is on it, so just wondering what other A-body guys are running.View attachment 1715500784

To cut thru all the b.s. , I went thru the same thing on ride harshness , and had virtually no front end lift on acceleration. The coils were 500# springs, I changed them to 300# springs , and helped some , but was still too stiff.
I then went to 250# springs and had to raised the adjustment collars up a fair amount to get my ride heigth back so my front end alignment would still be right.
It is way looser than before and rides mo betta , havent had it back on the dragstrip to see how much a little front end rise would help my traction problems tho.
Ur spring rate depends on ur cars front end weight and how long those shocks are , I even changed shocks out eventually. Mine are 12'' shocks .
