Especially when going over 60mph. At about 65 it is apparent. But, at about 70 it is reasonable. Over 70 is almost deadly (feels like the car is going to ride off the road).

These are on brand new roads as well. The county/state decided to fix up the highways and interstate lately so its been a good testing ground.

BTW I can cruise in my truck at 100mph with no problem at all. There seriosuly has to be something wrong with the camaro if my truck can do that.

I was thinking 1)Wheel balance, 2)Driveshaft, 3)Bad tires

Iv only had the car for a few months.

If it turns out to be the driveshaft, what is a good replacement (aluminum?) and where from?

Appreciate it.

 

Ok,I'm first(not randomly)this time. Your vibration dose it seem to come from the front of the car or does it come from under it? There are several things to look at. Let me know where you think the vibation is comming from.

You can PM if you want will cut down on confusion.

 

My car does this once I hit 90 on normal roads. On those brand new super smooth asphault ones I can do 105ish. I wonder if they all do this as well.

 

I had the wheels balanced today. Seemed to help some, but the shakes are still defintely there.
And it doesnt seem to come the front... more like underneath near the rear.

 

I'd take another look at the rims, one of them could be bent.

 

Change your U-joints,both front and rear. By all means check the rims,to make sure they are true. If it is bad you will be able to see ,just by spinning the rims on the car. While you have the drive shaft out check the trans mount,if it is bad change it now and I would recommend going poly,it's alittle stronger than stock.
