We put the light-weight, non-vented rotors/kit on our '86 Monte Carlo 4-speed Super Stocker last July. Haven't had any issues with stoppability. The car leaves at 8600 rpm and runs over 135 mph. At 3140 lbs. we had concerns we might abuse the rotors, but all has worked great for the past year. But I do agree, make sure the calipers are properly aligned on the rotors. This was somewhat of a pain, but worked out in the end.
