Wade, I 100% agree with the other two guys above me. I got back in to karting a bit ago and bought a BRM because they were a leader before my brake in racing. Little did i know that BRMs all but disappeared from my area. So i couldn’t find some specific parts for the kart and not many knew where to get them.
I would highly recommend you pick a chassis that your local track/shop carries. this way youll have a good support shop.
