I just bought a Racing Radios CM300D digital base station system for a new SR3. I have used Speedcom in that past which works well but the antenna is very long. This RR system looks really nice. RR ...

@charleyhradicalsportscarregistry-com car to pit, or car to coach/spotter. Not ready to race yet, but getting there. Btw I shaved 6 seconds after getting a custom bead seat - highly recommended!

Awesome, thanks for the legwork David, I just order some myself.
