The car in question. 2001 ws6/ hotchkis subframe connects, lower control arms, strut tower brace, springs,lower control arms, panhard, anti-sways front&rear/currie 9" w 4/10 gears/coddington 18" wheels/mich pilot tires/ baer 6 piston brake setup with 15" rotors/ jegg's torque arm( mounts in the tranny tunnel). Okay that's about it as far as suspenision/drivetrain mods. Last night was the first time since a few of these mods were put on that I stretched the car out. It started at 115'sh and got progressivly worse until I let off at 137. Mad vibration!! My steering wheel didn't vibrate at all, just the whole chassis itself. Kinda like riding a skateboard with real tight trucks. lots of vibration but still real solid feeling. I'm used to driving big lifted trucks where there is so much tire and shock between me & the road, there is never vibration. So after all this typing my questions are. . Is this kind of vibration to be expected? Not totally normal but acceptable? or Is my car about to break apart?

Thanks for the help!

I'd check driveshaft balance, alignment and the setup on the rear end (as well as bad/damaged tires). Mine is hands off stable and quiet at 153 mph (and mostly stock at the time).

Cme on guys, I'm sure I'm not the only one in here with these types of bolt-ons that has gone over the speed limit?

I can tell you that I would suspect that the Jegs torque arm will transmit a reasonable amount of noise and vibration into the vehicle (due to the way it mounts). The question is "what is reasonable?". without seeing the car, I really can't say. Sorry I can't be more help....good luck!
