Q Tech Types: 2 Questions: 1. Completed the Girling 60 caliper & 11" rotor upgrade on the '87 4Q, but am not impressed with the stopping power. Rotors are new drilled brembos being squeezed by MMs. Any ideas? 2. With the A/C on full blast, I get warm air. Fresh re-charge and new style rotary compressor. Guessing that a heater vent is sticking open. Any experience out there? Duane San Diego, CA
