Tony, one thing that will help with the heat problem is some wings that attach to the front windshield posts. the windshield pushes the air away from the car and completely misses the two scoops in the rear side windows. These wings run parallel with the posts (verticle) and are hardly noticable. They force air to make the turn at the windshield post and enter your side window and side scoop. Also if your coupe has a hollow rear spoiler you can create an air exhaust vent through the rear bulkhead up into the spoiler.Cut a slot horizontally along the width of the spoiler.It will end up looking like a 3rd brake light opening (a small slit).If your Kamm back has the kidney shaped detents do not use them for exhaust vents.there were some postings where engine exhaust was being sucked into the car. good luck on the sound prob...
Here is the email of russ thompson who makes the A pillar wings.
