do the adjustable lca send as much vibration or what ever through the car as the upper ones do.i dont suppose you can replace the hard bushings that come in them for the stop type.all i need them for is to adjust the pinion angle,not for racing.

 

Do you have any problems with wheel hop? If all you want to do is adjust the pinion angle I'd suggest going with some non adjustable lower control arms and an adjustable upper third link.

 

i have a upper control arm but it sends alot of vibraton through the car,just wondered if lowers were as bad.im going to see if i can replace the hard bushings with some stock rubber type.

 

I got ya. What kind of upper do you have? Some off different bushing options.

 

i have bmr but i dont want any of the hard poly type.im going to the parts store and go through the bushing book and see what i can find.

 

I think that vibration and noise all just come from the type of control arm. What I mean by this is generally a polyurethane bushing is going to be a lot more stiff than a rubber bushing, thus you will feel a lot more of the car's vibration and other noises. Most people hear a lot of "clunking" with more agressive bushings such as brass, hine joints, and polyurethane.
