It helps when your tech is into tracking and is the onsite tech at some events.
Best tech at my otherwise not so great dealership. Actually my ca is pretty cool and i got lucky but overall rating by customers are low. Got to go upstairs into the garage where all the work is done before and there were two m3's he was working on. They were pretty nicely modded but one was a vert. So he worked a coupe a vert and a sedan on the same day.
If you can find the right guy he can help you quite a bit. Find someone in cca?
Monkey see monkey do...I drive a poseur modified sedan.
