We race 360 winged sprint cars, and most of the IMCA modified teams have electronic scales one each wheel. We borrowed a set and weighed my cobra, and all four corners were off so much, I could not believe it.
I wanted to lower the stance and also set it as level as I could. I took everything apart and started from scratch. My chassis is a four bar and the heim joints needed replacing. I moved the top front bars down to make them parallel with the bottom. I made a tool out of aluminum that replaces the shocks, and has male & female threads with heim joints, then you twist the tool clockwise or counter clockwise to raise or lower the car. This way, I could adjust the ride height and be able to measure for what spring length I needed.
I replaced the coil overs to QA-1 and went from 12" springs to 10" on the rear. With adjusting the coil overs and using the scales, I was able to set the weight on each corner & front to back almost perfect. It's now 48/50 %, even with a big block.
If you want to borrow the tool just ask, or it's easy to make. It works great.
