My observations are that topless delete all friction and the air flow is more linear (better, less drag, eliminating extra lift potentially also). This seems to cancel the spoiler purpose and downforce however. Compared to the w/ roof where the air drops down on your clam shell, creating more drag due to friction BUT offer much better downforce.

Roof/no roof; which is better in a stock setup I have no no bloody idea man. You guess is as good as mine. Sure the track guys will chime in having obviously better knowledge on this subject than me.

TRK, hello?
