Strange vibration 997tt

[r1flyguy1]

Hi All

Was on a track day recently and when the mph was in the 3 figures around 135+ the was a strange oscillating vibration through the chassis!!! Nothing felt through the brake pedal or steering wheel

Any ideas?

Cheers

Did the car ever had a geo done?

My car was very nervous and moving around a lot at high speeds after track day. Geo at Center Gravity and all sorted.

And a visual to make sure everything is tight.

Mine had a vibration that only began at 140+ and was very irritating.

Turned out one of the rear wheels was slightly bent.

Cheers for that, how did you find out?

My car is under warranty and may be an issue I could get the garage to resolve

I would love to be there with you when you tell the opc there's a wobble over 135 leptons.

Balance out, or buckled alloy, on one side at the back.
Hunter Road Force will tell you which....

I mentioned it when I had my wheels refurbed and he spotted it when he balanced them.
