I have stock A-Arms with all Caltracs drag springs and shocks. Front springs are Moroso. I just put in a set of 2" lowering spindles. They hit the A-Arms and had to have them machined to clear. Is that at typical? The back is too high. wanted to put lowering blocks in but cannot find any that have 12.5mm stud. Any suggestions?

 

a machine shop should be able to make what ever you want

 

Common problem- Lowering spindles are NOT recommended for first gen Camaro's due to clearance and other issues...

Don't even think about the lowering blocks. It's a huge mistake as you'll get a wheel hop and you'll hate your life. Get the hotchkis lowering leaf springs for the rear and either cut the front springs or get the lowering springs on the front. That's what I did and couldn't be happier

 

To provide options and flexibility, I installed double adjustable coil overs from Viking to lower the front after installing SpeedTech upper and lower tubular control arms. Viking staff is formally from QA1 and these adjustable shocks should provided the quality and reliability that I need. With the adjustable coil overs you can fine tune the ride (drag, touring or performance) and the height.

 

I also went with the Hotchkis setup, 2" springs in the front and 1 1/2 leafs in the rear, It looks good but I cant comment on the performance until I get it back on the road. I also went with Energy Suspention poly bushings while I had it all apart, no special mods were needed for the instlations.

 

Questions, is this a street car or strip car? If a street car, I would not use Moroso trick springs and in fact they don't recommend it either. They are too light and will make that car bounce all over the place plus. I'd go with a QA1 setup or the brand 68hou used and also do as others said and go with a lowering rear spring kit.

 

There is much more involved than simply lowering a car. To do it right, you should be thinking about making it handle better in the process. I would recommend you check out RideTech. The 48 Hour Camaro build link below might give you some idea of what is possible with properly matched bolt on parts.
