Suspension problems

If there's already a thread like this, please link. I didn't find any.

So, I was editing the Moonhawk to make a race/drag version, and I had a bunch of problems with the suspension.
The front suspension (below) is fine, but a bit too bouncy. I've lowered BeamPrecompression to 0.9, and stiffened the springs. I also increased dampening. I've tried increasing both of these numbers to ridiculous amounts, with no results. It also seems to have a crap ton of negative camber.

Code:

"beams": [
          ["id1:", "id2:"],
          {"beamPrecompression":0.9, "beamType":"|NORMAL", "beamLongBound":1.0, "beamShortBound":1.0},
          //front shocks         
          {"beamPrecompression":0.9, "beamType":"|BOUNDED", "beamLongBound":0.0, "beamShortBound":0.25}, 
          {"beamSpring":242000,"beamDeform":68000,"beamStrength":188000},
          {"beamDamp":4300},
          {"beamLimitSpring":241000,"beamLimitDamp":1600},
          ["fh4r","fs1r",{"beamDampRebound":3400}],
          ["fh4l","fs1l",{"beamDampRebound":3400}],
          {"beamPrecompression":1, "beamType":"|NORMAL", "beamLongBound":1.0, "beamShortBound":1.0},
    ],

And as for the rear suspension, the ride height and stiffness are fine, but it goes all shaky between 100-180 kph. Again I've tried several combinations but couldn't solve it.
Springs:

Code:

"beams": [
          ["id1:", "id2:"],
          {"beamPrecompression":0.92, "beamType":"|NORMAL", "beamLongBound":1.0, "beamShortBound":1.0},
          //rear springs
          {"beamPrecompression":0.92, "beamType":"|BOUNDED", "beamLongBound":0.08, "beamShortBound":0.45}, 
          {"beamSpring":80000,"beamDeform":174000,"beamStrength":251000},
          {"beamDamp":0},
          {"beamLimitSpring":211000,"beamLimitDamp":1200},
          ["axsr","rs1r",{"beamDampRebound":0}],
          ["axsl","rs1l",{"beamDampRebound":0}],
          {"beamPrecompression":0.92, "beamType":"|NORMAL", "beamLongBound":1.0, "beamShortBound":1.0},
    ],

Shocks:

Code:

"beams": [
          ["id1:", "id2:"],
          {"beamPrecompression":0.92, "beamType":"|NORMAL", "beamLongBound":1.0, "beamShortBound":1.0},
          //rear shocks
          {"beamPrecompression":0.92, "beamType":"|BOUNDED", "beamLongBound":0.08, "beamShortBound":0.45}, 
          {"beamSpring":0,"beamDeform":174000,"beamStrength":251000},
          {"beamDamp":2700},
          {"beamLimitSpring":211000,"beamLimitDamp":1200},
          ["axshr","rs1r",{"beamDampRebound":3000}],
          ["axshl","rs1l",{"beamDampRebound":3000}],
          {"beamPrecompression":0.92, "beamType":"|NORMAL", "beamLongBound":1.0, "beamShortBound":1.0},
    ],

Thanks in advance to anyone who knows how to solve these issues.

Also, could anyone "translate" the spring rates to an actual unit? I just change the numbers but I have absolutely no idea what I'm doing.
