Question Steering wheel vibration at 100 mph and faster?

Hey Guys, I'm new to Porsche. My care is 03' turbo 911 with about 61,000 miles. It's under certified porsche warranty. It was vibrating at 70 mph, I took it in for a wheel balance the shop said they do it under high speed balancing. The car drove fine up to 95-100 mph then the vibration comes back. Ideas?

It could be so many things. Are you on stock rims? Are the tires good? wheel bearings? CV joints? Basically anything that rotates should be looked at.

I would find a shop with a four wheel dyno and safely run and find the problem on that.

Also if re-balancing the wheels moved the speed that it vibrates your on the right trail.. May be a bent wheel, bad tire or just a bad balance; then again it could be so many things like todd said
