Perhaps I'm jealous of what must be available elsewhere, but the spin balancing recommendation must be treated as one of those "nice to have" --as opposed to necessary -- things. I recently called every tire shop, alignment shop, etc. in Denver, Fort Collins and Boulder. NONE of them did on the car balancing and they said that they knew of no one in the area who did this anymore. I asked why and they all said "because it didn't do a better job and it was dangerous". Yes, a couple of them were high performance/race car places. I went with a local place that does computer controlled balancing (off the car) and alignment. I just completed 4000 miles in two weeks and never has the car steered, cornered or just plain ridden smoother. Oh, I found a place in Denver than does industrial vibration dampening and they said they could do on the car balancing, but wondered why I wanted such. They also said they charge by the hour and have a minimum!! Dick Ryan VIN 16867
