My whole dash board and car shakes pretty crazy when im hitting like 80mph+. Could it be my sub frame connectors? Help. Specs:96 z28, 216k on odo, 16k on rebuild

 

Bent rim?

 

^ Like my rims with tires or my rim from my bodY?

 

What?

and no, it's not your subframe connectors

 

The stock driveshaft has been known to cause vibration at higher speeds.

 

The drive shaft probably needs to be turned 180*. It's balanced and it matters which way you put it on.

 

I would also question the balance of your front and rear tires/wheels. If a couple ounces of weights accidentally fell off one of your wheels, it could cause it to shake pretty well.

 

If you have a steel driveshaft, its the suspect. GM had a lot of problems with unbalance steel shafts leaving the factory. If thats the case, pick up a used ls1 aluminum one.

 

^ Where can i pick a used ls1 driveshaft and how much?

 

At a junk yard or ebay or the For Sale section.

I bet it is the driveshaft because my girlfriends camaro does the same thing at 80+mph. I thought it may of been the tires not being balanced or something, but she just got new tires installed and balanced. I just put a ls1 driveshaft in my camaro, some people put those in to get rid of the vibration, but i did it because it was a 70 dollar aluminum driveshaft on ebay + 30 for u-joints and a easy 5 hp, but dont use aluminum driveshafts if you plan on going with high hp numbers.
