The car rides so nice now piggy i cant even tell you. The tires were a lot of it. I could drive this thing to texas.
Vibrations i beleive consisted of, exhuast hitting the car, the control arms just adjusted to aggressive for everyday driving, the driveshaft not hideing anything. the nittos just being a hard tire. Great for the money and performance but hard. Its a really a combination of things.
The metco upper is part of it as well, thats a real stout peice meant for heavy duty stuff but it just transmits all the feedback through it.
Its not easy to track it all down. Individually the parts themselves are not really the cuase, but its getting it all working together right for your application.
