That is a cool comparison.

So from what I am gathering, and assuming you are talking about downforce per streetpro's comment, adding a little downforce to the front would be my first step.

I personally am considering swapping to M3 front bumper or adding a like a lip/dam. Next would be rear spoiler or, and I haven't done research yet, cutting up the rear bumper to relieve pressure buildup (this is common on miatas).

From there you could get into more advanced things like vents in the fender and brake ducting, etc.
