Wheel shaking at high speeds
 

Hey guys, ive noticed that when im on the highway and doing 120 KM/h (72m/h) the steering wheel shakes alot. I back down to 110km/h and its fine.
What is causing this? i know i need new front brakes+rotors (anyone wanna point me in the direction of a guide for this).

any ideas?
(JUST BOUGHT THE CAR AND IM SOOO HAPPY)

First place I'd go is tire / wheel balancing.

if the wheels ARE in fact balanced, my next idea would be the brakes... I know my caliper was sticking once warmed up, one of my flex hoses had collapsed.. so it caused a nasty vibration...
if your getting your brakes done, look into flex hoses.

+1 on wheel not balanced first. Second check the brake components. Third suspension parts.

shake at ~ 30 - 40 MPH, tires out of round
50 - 60, wheel balance
70 -80, shocks.

check to see if they are leaking at the lower spring mount.
also, loose bushings or ball joint will amplify this.

as for brakes, I use only factory pads and rotors.
oem are of a generic compound and could cook the rotors.
sympoms are a severe vibration around 60 MPH, after driving
5 - 10 minutes, and light brake pressure.

I experience this also when traveling at higher speeds. I recently changed my bushings in the front to performance tuned bushing and it helped a little. I know I need an alignment so that may also be the issue. My shocks in the front are shot, could be another symptom.

I got my Ti not even a month ago and had the same problem..
after driving the car for a while the shaking was reduced to almost nothing, I am sure that if the care was sitting for a long time the brake components maybe be rusty...
