1972mc Posted May 5, 2022 Share Posted May 5, 2022 It's been a long long time since I've posted so Hello. I need specs to take advantage of the geometry improvements of tubular U/L control arms jegs and qa1 coilovers. I don't want an autocross setup- just a cruiser for my weekend jaunts in the country. Getting her ready ro drive to Carlisle next month. Thanks for anybody's experience. Carl Hanson (VA) 3 Quote Link to comment Share on other sites More sharing options...
71SSclone Posted May 5, 2022 Share Posted May 5, 2022 Did you try checking with the manufacturer of the control arms? Ive been wondering this myself as I want to upgrade my control arms and wanted to know what specs to use. Quote Link to comment Share on other sites More sharing options...
Leghome Posted May 5, 2022 Share Posted May 5, 2022 I took my 72 to an alignment shop where the guy knew old cars and could set it up accordingly. These kids today have no idea on how to set up our cars correctly. I used thee dealership I sworked at part time and They did a decent job until I got Bruce to look atit. he said it was close but after he adjusted it it was perfect 2 Quote Link to comment Share on other sites More sharing options...
1972mc Posted May 5, 2022 Author Share Posted May 5, 2022 Jegs has no written specs on their site and I did not bother to call and talk with a "kid"(: Having scoured many posts, and mag articles here is what I'm going with: .5 negative camber 4.0 positive caster 1/16-1/8 toe Quote Link to comment Share on other sites More sharing options...
Blackhawk Posted May 5, 2022 Share Posted May 5, 2022 https://www.ridetech.com/tech/suspension-tuning-guide-high-performance-vehicles/ Get as much positive caster as you can without having the shims too unequal from front to rear. Quote Link to comment Share on other sites More sharing options...

I was going to do 4.5 positive caster, -0.7 camber, and 1/16 toe in. Quote Link to comment Share on other sites More sharing options...
amsterdam84 Posted May 6, 2022 Share Posted May 6, 2022 Are you sure the jegs control arms fix geometry issues? I thought I'd read they were basically tubular control arms built to factory specs. I personally went with QA1 control arms and the Viking Performance coilover set front and rear. Quote Link to comment Share on other sites More sharing options...

Some tubular control arms are built stock specs, while others change the suspension geometry. Need to find out what you have. John Quote Link to comment Share on other sites More sharing options...
