2003 911 front end shimmy
 

2003 Porsche 911 Cab. 56k miles. Looking for guidance and / or ideas to resolve a slight front end wheel shimmy problem when traveling above 70 MPH and slight pulling/fading to the right. I purchase this car 3 months ago from a local Porsche dealership. Dealership has acknowledged this shimmy and they have been accommodating but they have not been able to resolve the problem. Car has new Continental 225/40 ZR 18 92 YMS on front and 285/30 ZR18 93 YMS on rear. Just recently had wheels Hunter Road Force balanced with left front at 12 lbs, right front at 5 lbs, left rear at 7 lbs and right rear at 21 lbs. Also had aligned; left front camber .08 & .05 toe, right front camber .14 & .08 toe, front total camber -.07 and toe .13. Rear left -1.34 camber and .22 toe, right rear camber -1.15 and toe .24. Total rear toe at .46 and thrust angle -.01. All other allighnment data is “……”. Dealer identified right rear wheel was bent and was sent out for repair and reinstalled before above adjustments. Dealer also substituted a complete set of balanced donor rims and tires to rule out issues, but car continued to have shimmy and fading with donor set.

Take it back to the dealer. BTW, welcome.
