If you have your wheels road-force balanced you could get rid of most of the weights. The problem is that the tires are not 100% perfect. You have to add weights to the rim to be able to correct the imperfections of both rims and tires. Road force will use the imperfection of the tires as a weight by rotating your tire where it best suits the rim. Best balance you can get!!!

 

Thanks Mr. Stang for the information and sharing the photos. My CS/GT is about 1-year old and I recently tried the Meguiar's Clay Bar. Man, am I a believer -- very pleased with the results. Lot of work (I washed the night before) and then did the clay bar + wax the next day......but well worth the time.

I was a little worried as a first-timer trying the claybar, but very easy to use and definitely worthwhile.
