Ventilator presents actually a great idea. To simulate disc brakes. I know it sounds out there, but as the gaming industry progresses- detail like that is becoming common. Back in the day they had to hardcode stuff and 'fudge' it because the computers of that day could not hold that much activity in a fast paced game. Now, most any new(ish) computer would be capable of this without much worry, and it makes it all the more realistic when you do it exactly as it works in the real world. I've read up a lot on that kinda thing and it's almost always a good idea to create everything as high up on the heirachy of detail as you can to give an even better playing experience. Then again... on the flipside- who's gonna notice that kind of detail. There is an overboard factor. I'd think this is a perfectly fine solution as long as your sys req specs are above a 500mhz pc with a 32mb T&L video.

Just my two cents and five nickels on the side.
