Jason told me to go to Mr. Tire in Pasadena on Mountain Road. They have all the best Hunter equipment also. Owned by Joe Tomarcio, (Mr. Tire), he's also a Viper owner. He hosted an all day training session for us last spring at this shop, correct alignment techniques, balancing (a much deeper subject than I realized) lowering problems etc. I was happy with my service prior to the seminar, and really impressed afterwards.
