Coilover Spring Rate

[trials935]

Anyone have a chart that compares torsion bar sizes to coilover spring rates? Trying to turn a track 930 back into a street car retaining the current coil over shocks and struts.

My @911ratrod has a street coiler setup from Clint at Rebel Racing. It's the same setup he, Steve Wong and many others on the west coast run, apparently. It rides really nice and smooth, while also cornering nice and flat. The car feels as nice as my 996 Turbo, generally speaking.

I believe I have 200-250lb up front and 300-350 in the rear. Some combo like that, could even be 200/350 front to rear. The front shocks are bilstein RSR's, the rears are Bilstein RSR's also, valved for those spring rates.
