I'm not sure what version the coilovers are. I had them for a year and a half, the street series. I'm riding on 225 18" rota's at 35psi f and 32 psi r. My camber is at -.5 f and -1 rear since I do a lot of freeway driving, at least used to, zero toe as well. There is still a lot of adjustment with these, I can drop it to the wheel well or raise it "like a 4WD buggy"
. I don't know what the damping curve looks like. I talked with the Megan rep a while ago and asked what the critically damped setting was. He didn't know what I was talking about until I explained my self. Critically damped is the setting where there is no overshoot after a bump. He didn't know what the optimal setting was. I know the 2.5in springs are different than normal springs you would install with regular stuts. I was looking on eibach's sight and you can get pretty much any spring rates and length's you want. lots of choices. I think I will try softer spring rates on the megans first and if it doesn't work, try a different option. Thanks for the feedback
