wobbly car...
wobbly car... Was playing around and did 150 run, and now lately at that speed rear end of car just starts swaying and feels like a boat. Used to do 150+ like I was riding on glass. Mods are at www.cardomain.com/id/ozorowsky. What kind of stuff should I look into to fix this?
alignment was maybe 10k miles ago. Shocks are good. I'm using Dynamic Motorsports upper, lower PHB, and LCA's. Also have spohn torque arm. Wobbliness wasn't this bad, but recently converted A4 to M6 and now seems to be kind of bad.

This may sound kinda dumb, but I read once that with the M6 drivehaft there was some balancing issue at high speeds, not sure what year but it was something about switching to another year one... Just trying to help.

Get that DS checked!Was it a fast "vibration" wobble or was it more of a back and forth "sway" like it was the car not being stable and the rear tires breaking loose and skating? I doubt the later, so I'd agree that it could in fact be a drive shaft that doesn't like something @ that speed. Though wouldn't you still notice it at a lower speed or a higher RPM?

Verdad Gallardo The tires were not breaking loose, but did have a skating feeling. Like being on a boat. It was like the car is twisted and back was going one way and front going another. It MAY have been the road. Don't start noticing it until about 120 or 130 mph. Just can't put my finger on it.
This may sound dumb, but I WAS goign over a bridge. Maybe there was high wind coupled with car going 150 mph bad idea. Just MAYBE. But still doesn't hurt to check other stuff out.
Drive shaft was the same one on my auto. Never had any problems.

I remember reading the same thing about the DS somewhere. Yes it could have been the bridge, but I've done the same thing in a family sedan
Even crusing @ 75 MPH, the car on some bridges feels like it's skating, but that's just do to the fact that I'm trying to aero correct. Dunno though, as the f-bodies are pretty slippery on all profiles to air, I guess if it is hitting you right at those speeds, you would feel it though. 
safely and still get you're DS checked. It might just not be lined up properly since the swap which could throw it a little bit out of balance and cause this. GL.

Ya know, maybe it's just me, but doing 150 mph on a public road not designed for those kinds of speeds is a bad idea too. At that speed anything can disturb the aerodynamics of the vehicle... and any imperfections in the road surface will be magnified. IMHO, don't drive like an ***.
Your shocks mostl likely aren't good. Don't assume they are..... They don't need to be leaking or clunking to severely lack damping control. And when they do, you feel like you are on a boat, the car just feels disconnected and floats around.

IMO, if I don't wear a seatbelt, whose in danger? ME. If I drive 150+ at 1am, with no one on the bridge, whose in danger? ME. In my opinion I'm not driving like an ***. Don't see you cautioning me when the army wants to send me to Iraq/Afghanistan, so keep comments on topic. Kthxbye

As for the ride, I agree 100% with Sam. He knows his info and he's a good guy. Your driveshaft has nothing to do with the skating feeling you get in the car.

And please keep the Army out of it. They have nothing to do with how you comport yourself on public roads.

Why would shocks be "wobbly" at higher speed but not
(say) at 100MPH? I don't get that bit. Though if there
were some tire-out-of-round action the shocks I guess
would help keep the rubber down. To that point, you
might want to check the tires for any imperfection at
all, spin them looking for even radius, sidewall bulges
and so on.
You could always get a "ricer wing" and aerodynamic it
all up

I'm sorry if you're having a hard time understanding why driving over twice the posted speed limit on a public highway is a bad idea, especially in an unprepped car. There's a reason muscle car owners have a bad image in the rest of the population, but I can rest assured that people like you are working hard to help fix that.
Did you order new shocks yet?
