All of a sudden I started feeling massive vibrations while driving on high speeds @ + 210 KM/H (+120 Mile/H) … I never had this problem before! I Just noticed it today!

It can't be my tires, because their new (PS2 fitted in April 08, made in Sept 07).
I have the spydershaft, but if fitted wrong then it should vibrate from + 120 KH/M (+ 80 M/H) ... so I font think this is the problem!


Any idea what that might be from?

thanks.

its prob a tire balance issue or one of your rims has a small bend in it and you feel it more with the new tires. that would be the first place i start checking

Do you have aftermarket wheels?

And if so, are the rotor clips still installed?
They cause the rims to not be fully seated against the rotors
and all sorts of vibrations start appearing at high speeds.

Yes I have aftermarket wheels .. I have 19" SSR Comp-H 9.5 all around .. link below ...

sounds like it should be in the wheels/tires....could have thrown a weight recently

If this problem just started and you have not made any recent mods,
check bolts at driveshaft flanges, have been known to come loose.
Should be loctited.

My flange bolts were loose after 5K of driving.

If your rims have a depression on the mounting flange where the
clips would be like OEM wheels, the clips are not a problem. If you
aftermarket rims dont have the same depressions, the mounting
flange wont sit flush and the rims will not be running true, hence the
vibrations. It also effects the flatness of your brake rotor as the
tightened lugs will deform the hub and cause the rotor to be deflected.
Also the lugs have a chance of loosening up because of the clips
and the inability of proper torquing of the lug nuts..

I took the car to the shop, and I checked the tire balancing on all wheels. Turned out the 3 of the tires weren't balaced! .. needed to add some g's to each tire.
I fixed it, but couldnt get a chance to push the car to the high speed i faced the problem with ... I will try to do it tomorrow.

thx again
