Skid

Have some back -to-back Area 27 dates this summer and wondering what if any shops exist in the valley if say need to change tires on the rim, get a diagnostic or minor mech repair?

The two that I know of are:
Velocity AP - https://www.velocityap.com/performance-shop/
JF Kustoms - The race prep part is run by VCM Autoservice - https://www.jfkustoms.com/

Not sure when you are there, but if they are doing a test and tune day you might be able to have them do track-side support for you at the same time.

Haven't been there myself, but Big John's Tirecraft in Oliver was recommended to me as a nearby shop that's familiar with track cars.
