Driving
 

Hello

Need help. I own a 2005 997. When driving normal speeds I don't have theissue but when driving over 100 mph+ the car will start to wonder to the leftor right. I have 305/25/20 in the rear & 245/30/20 in the front. Coil oversand bigger rear sway bar. Is it my tires? Is the car to low? Is the steeringrack? I have taken the car to 3 different shops for alignment. The car isusing 14mm rim spacer in the rear and 7mm in the front also.

Any ideas would be appreciated.

Thanks

You might want to start with the tires...my 03 911 is now equipped with Toyo Proxes 4's all the way around and they are super stable at high speeds.
