anyone have any thoughts on this? I did some physics models of the b13 suspension with Hyperco Gen 2s and found that critical rebound damping is around 975F/610R nm @ 13" /s.
The b15 koni yellow sports have the following specs:
min rebound: 1050 newton meters @ 13" per second
max rebound 2100 newton meters @ 13" per second
compression: 450 newton meters @ 13" per second
That might be useful for tuning ride quality over severe bumps, but usually handling type tuning takes place at 3"/sec and below.
Do you happen to know / have measured the motion ratios for the B13? I have an excel chart that can be tweaked to calculate damping at various velocities. I'll need to corner weight my own car to verify curb weight and f/r distribution to make it work.

I could probably come up with a pretty decent force curve for hyperco specific revalves.
