body shake
just purchased a 2002 z06 which is lowered 1" all the way around on stock bolts. At high speeds +120 the car begins to shake from side to side under acceleration. Has anyone had this problem before, is it because of the lowering?

From: Not on either liberal coast.
Could be the alignment, failing/failed suspension components, or due to the lowered suspension w/o an alignment by the previous owner, tires and/or wheels, etc.
Handling is not always improved when the lowering is done. GM recommended only 3/4" maximum on the Z06 cars (for racing), but most owners can't leave well enough alone. I prefer function over form.

Here is my .02, mine is a 01 Z and bought it bone stock (factory stock), car flex specially on bumpy rd or uneven rd/highway, but it dont vibrate or tire balancing isssue, tires are pretty good low mileage only 35k miles on it, well i lowered around 3/4"-1" not more than that, it still drive the same way before lowered, So the verdict is too many variable not just one alone:
Like:
Shocks - Upgrade to Pfadt (very Expensive but they r 1/2" shorter and easy to to adjust ride hieght) or C6 Z06 only $240 from Gene cully good shocks for the money but not the ultimate.
Control Arm bushings (factory rubber not last long) u can upgrade to Poly-urethane from Pfadt or VB&p or other vendors,
Sway bar bushings,
Tires effect too, but since they r wider so, not much we can do specially on rough/bumpy/uneven roads.
And ofcourse lastly Alignment and balancing tires.
Good luck and iam bout to order Pfadt transmission brace, Pfadt Shocks, if budget allows than Pfadt Bushing kit and Engine mounts too and ends with alignment and balancing of tires.
