i dont think im lowering my car......but i do think im geting a carbon hood....and maybe a stock style carbon wing......ill let you beat me....im not into the racing really.just something to fix up.your car is why i got the rims too.......thanks for the nice comment

 

You need to get an alignment bro (as stated before), that's the only logical reason why they are shaking at speed (not to mention the only reason left). That's a "new" car so you can rule out the suspension being bad unless you've hit a lot or even a few curbs.

*edit*
Have them check your balance anyway.

 

so alignment causes the shake ???.....i am noticing when i hit the brakes its also wanting to pull to the right.... but like i siad it was driving smooth as silk with my centerlines

thanks.... guess ill get a alignment.it also seems to want to wander alot with these rims and tires

 

Can you feel the vibration through the steering wheel?

 

yes just around 45 to 50 somewhere around there.then its fine

 

It's fine after 50mph?

 

yes and below 45

 

Hmmmm....Easy answer: take it back in. I put my money on a bad balance job.....

 

yea im going to call them tommorow thanks

 

If they took the wheels off or put them on or both, I bet they used an air rachet and torqued it down more than it's supposed to be and causing your rotors to warp...that's another cause of shimmying. Undo the nuts and torque them down properly and see if that doesn't take the shimmy out. The pulling to the right with the brake applied is a quick indicator to brake issues...make sense?


Shaking and shimmying will happen at all speeds if it's balanced improperly, the S&S will happen at higher speeds if it's an aligment issue and it will also pull to one side or the other + it will not stay in a straight line and an improperly balanced will worsen it. What you've described in your more recent post is a brake issue and it means that they tightened the nuts down too much and improperly (as I would describe it).
