I didn't have time to order air bags since i am going to the track tommorow but i found some old stuff i had laying around in my shop. A mr gasket coil spring control part#1280. I used one of them in the package to stiffen the right rear spring and seems to have worked ,car leaves very straight. Car sits level too. I thought by putting it in the spring it would jack the right side up but it still sits level. Just was wondering if anyone else had tried this? It is very adjustable too. I think i am going to use the other one in the package but i will have to buy more nuts.
