Road Force Balancing Performed ** BIG Fan ** - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Had a shake @ and above 60 MPH in my Cayman 'S'. A local Indy shop suggested a road force balance due to the size/width. Shake is totally GONE, completely new drive even at slower speeds! The print out showed the previous balance so far out of whack they might as well as thrown the weight from across the room and hoped for the best. Highly recommened, I paid $100 for it, took an hour to complete.

I had mine done when I put my Yokohama S. Drives on the rear of my 01 S. It is so much better than older machines. Also one of my rear tires required no weight adjustment at all. That is good manufacturing for a high speed tire!

Ditto! Road force balancing is definitely worth the $100. And, it's for the life of the tires.

Hey Todd, The new ride looks good! Your old ride is still looking great in my garage as well. I have 2 new drive axles, a new motor mount, new fuel filter, and new spark plugs setting here waiting on the temp to drop enough for a long day under the car. Best of luck with the Cayman!

I'm not familiar with Road Force Balancing. Please elaborate.

What do you mean for the life of the tires? A weight can still fall off. Do you mean they guarantee it stays balanced for the life of those tires?

Just curious man

Road force balancing refers to the way the machine turns the tire. On old machines the tire was spun on a spindle and there was no contact between the tire and any surface as there is when you drive. Road force balancing uses a drum to turn the tire like a road surface. This allows for the natural deformation of the tire side wall just like you have when the tire is on the ground.

The computers are more sophisticated and can tell you if the wheel is out balance, if the tire is flat spotted or if the tire is out of round. This is in addition to better balancing.

Never heard of road force balancing before. Learn something new every day. Thanks.
