I remember a thread a long time ago. Can some one tell me the benefits of raising the rear of the btoom. Do you think it would have any effect on air flow over engine lid, in a positive way?
Opinions?

whatever you do, don't spin...that roof will last up there for about .05seconds before getting launched into the air (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

Sort of like the roof flaps that NASCAR added a couple of years ago. When a car spins at speed and starts going backwards the flaps open and break up the airflow over the roof to keep the car from launching upward. Of course their flaps are built a little different and are of course "NASCAR Approved"! These were actually one of NASCAR's best innovations, IMO.
