Free suspension Kinematics and Compliance data - modern performance cars
Hello all,
I'm working on spring and sway-bar selections for my 1968 Firebird, and I wanted to benchmark some newer cars to see if my design was in the ballpark. Usually, real data is hard to come by, but I vaguely remembered seeing some kinematics and compliance (K&C) measurements for various cars in Car and Driver magazine a couple years ago.
I dug though the archives on Car and Driver's website and finally came across the data I was after. Car and Driver had Morse Measurements do K&C measurements on several of their long term test cars that year. Morse Measurements uses a fancy kinematics and compliance rig to measure actual vehicle behavior, and I have high confidence in their data.
I found the data very valuable, and I hope you do as well. I've attached the .pdf's I downloaded from Car and Driver's website below. I don't think there is any issue in sharing these since they're readily available online (if you know where to look).
Useful data includes:
- CG heights
- Roll center heights
- Suspension stiffnesses (so you can calculate ride rates etc)
- Roll stiffnesses
- Anti-squat / Anti-dive
