Will be interesting to see the comparisons once you get some info from the logger.

I guess the front spoiler/splitter must aid the movement of air over and around the body.However at the same time it is drawing air in at the front creating drag and probably lift.In your case it seems you have some track time so it will be really interesting to see how the car performs all round, inc cornering and at high speed.As Spannermanager points out it will bit different for a circuit racer compared to a road car due to ride height but keep us posted.

Lastly the old Kafer cup cars is where I got the inspiration for mine,I would imagine there are benefits of a splitter /spoiler or they wouldn't of used them
