So, after much thinking and thought, looking and looking, I have finally found a very cheap and simple method to making the underside of your mini RaceCar Smooth!!!

For about $40, you too can have underbody paneling for your mini!

Increase Speed! Increase MPG! Reduce road noise!

Buy Now! lol. jk, its free! check my pdf!

 

Did you ever find out if this actually helped?

 

It def makes the car quieter for one. Hard to tell if mpg is improved, which is a disappointment. Car does feel as though it accelerates faster from 60 to 90, due to less drag.

 

Quieter is more what I'm looking for, just a little less road noise. I want to hear my mods, or my music more.
