I'm rebuilding my rear suspension..and have everything out. Was wondering if I should buy new coil springs, is there anyway to test my current ones to see if they need replacing?? or should I just do it to be safe.

Thakns.

without compression testing gear about all you can do is look to see if the hights are the same and maybe measure the compression with a large weight and a ruler

Or you could find somebody you know that has several pairs stashed away from cars dismantled long ago?

Thanks...I do have 2 sets, and they are all the same height just don't know about the "rebound" part. I guess I could stand on them, but how do I know how "far" they are supposed to go down. I was reading some previous posts about springs from coilsprings.com, they offer one that has a rate of 180lbs (for extra weight), vs the stock of 150lbs...wonder if these would do better with the Koni shocks I have. decisions, decisions.

What about a hyd press with a Psi gauge hooked inline and compare the Psi and the height of the individual springs? I don't have any idea how much the compressed spring height is in the car though. Not much info in this post, just a thought. Jarrell

To do it right just take the springs to a shop that works on race cars. A phone call to your nearest speedway should get you the name and number of numerous local racers with the equipment. Mine were done by a shop just two blocks away. The tool is really just a hydraulic press with an electronic load cell (measures the weight on it) and a measuring apparatus with a dial indicator. The guy did a spring in half a minute while I watched. And wouldn't take any money. What a guy!
