Re: Mtech kits, better aerodynamics than OEM?
Should be better else no reason BMW made it. In fact, they do testing on those aerodynamic kits before world wide commercial launch. Similarly for the new M tech kit for E90
Generally speaking, the lesser the air underneath the car, the lesser the effect of drag and lift.
Take a look at the CSL front splitters which are designed to scoop up some of the air and channel it ard the front bumper into the air dam or brake inlet ducts etc. This creates improved aerodynamics for the car when travelling at higher speed.
And as you would have noticed, those CSL splitters are somewhat similar to the M'TechII's corners with the exception that former ones are a bit more extended to the ground. In fact you can buy those M-Club splitters and put them on the M TechII corners. Couple of guys here have them. Check out Sam (the moderator)'s signature.
In additon ...for a car w/o a flat, sealed underbody it creates another turbulence underneath and it's not optimal. In this case, a full front lip will be a better choice ( eg is AC Style lip fitted on E46M3). Applying the concept into racing, look at those GT/Le Mans race cars. They typically have big splitters/lips that cover almost the whole front bumper and not only that, they extend out for a few inches. This is to help direct as much air as possible away from the underside of the car.
Some of you might have noticed that underneath the engine bay is a piece of big black plastic cover. That's not exactly engine cover but it's a form of underbody seal to prevent air from entering up too much into the engine bay area. Now go and check your car..If u don't have it then go and buy one. Those who are collecitng their new rides, ensure u have that cover. I had seen one of the guys new rides that didnt have it and only realized that after months of driving.
Cheers

Always thought the big black plastic cover is to prevent oil from dripping onto the carpark floor! Thought BMW was so considerate...

I think it is only applicable to the M-Cars that are capable to do at 200km/hr plus. Standard car drving around town should not have much impact. If add downforce for the front, do remember to match one for the rear.
