Correct spring rate for QA1 coilovers

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.20200322_154748.jpg
