Leaf Spring to Coilover Swap

#1 Post by 71 Nova » Fri Dec 02, 2011 10:09 pm

My Camaro presently has ladder bars with mono leaf springs and some kind of non adustable shocks out back. I would like to switch to coilover shocks. Looks to be pretty easy to do, but I'm not sure how to figure out how much travel I should use. Any suggestions on how to figure this out? :scratch:

Details on the car are here => 68 Camaro, except I now have the 408 SBC (650 HP) in it.
69 Nova 408 SBC
Best to date: 10.241 @ 128.36 mph 1.404 60ft.

I have always been told to buy the longest shock you can if you have adjustable brackets. If it doesn't adjustable brackets than you need 2"-2 1/2"s of shock shaft showing at ride hight.......

What supernova said
I am not really sure what the question is, but I am pretty sure the answer is Big Block.

I just recently talked to my friend from S&W about QA-1 coilovers and here is what he suggested I should use, but keep in mind, this is a single adjustable shock and you may want to go with a double adjustable.

QA1-50-019A: 16-3/8" extended, 11-5/8" compressed - uses 12" x 2-1/2" spring, recommended ride height 13-1/2"-14".

I also use 130lbs. spring and like the others stated, an adjustable lower shock mount.
Those who think they know it all have no way of finding out they don't......... :scratch:

The advice you got from S&W was fundamentally sound. You'll like this longer shock because it will allow the rear end to separate from the car more when you're swapping slicks.
