I was curious about what would be said about it.
Way back when only concerned about unloading the LR that's what we ran with our UAS K30 on our bandit chassis with a stiffened up left rear chassis via an additional engine rail added inboard the factory two rails. Use to sound on the track coming off the corner like a super late does today pulsating the engine sound when it grips and releases some and then does it again. You could hear the kart hard laying down on the RR same as I hear super lates today.
thanks for the replies and today it would not be successful running mainly off the RR.
