If you're competing on track days you'll want to dig into the rules to keep everything kosher with the Tech guys.

For the most part I'd like to avoid large new pieces in the rear just from an aesthetic standpoint, so I was thinking a couple rear spoiler fill-in panels (don't know the technical term... think Mazda CX-5, under its hatch spoiler) and trying out VGs just aft of the rear quarter window.

I unfortunately have to leave most of it in, except spare tire. The Mazda3 rear suspension toes out as you lift it up, so when my normal alignment is 0.00toe all around, taking everything out for the track makes the rear end VERY sketchy under braking. I just kinda deal with it as tire wear and street mpg's are more important to me.

As soon as I figure out a clean way to do it.
Thanks!
