My question is this: which id any of the M performance parts are actually functional? 3E production race car rules in Australia allow us to run a factory or dealer option body kit or spoilers, but if it's just for looks, its just going to slow it down. Anyone know the answer? or is there any actual testing yet?

Are these "aero" parts actually functional? Is there an improvement in down force or is it just looks?

I have consulted with the dealer. If the M performance kit is fitted, the car needs to be recoded to suit the new downforce and aerodynamics.
