Don't forget that when you use a CM cage instead of a 6 point MS roll bar the tubes can be a smaller diameter and thinner wall which saves some weight in the overall installation. Consult with a chassis builder for specifics but the weight savings is pretty significant since several CM tubes in the cage can be less than 1/2 the required wall thickness of MS. As buzzinhalfdozen points out his CM cage was lighter than his MS roll bar. Generally speaking a properly sized 10 point CM cage weighs about the same (within 10 lbs) as a 6 point MS roll bar!!!
