#2. Rotor Cooling Theory - from Brian.McCarthy@intermec.com
Top
Date: Mon, 30 Jan 2006 15:43:32 -0800 From: Brian.McCarthy@intermec.com Subject: Rotor Cooling Theory M3 front rotors aren't interchangeable. The ventilation vanes between the two disc surfaces point in opposite directions. The vanes are curved, similar to the vanes in a jet engine. The vanes on each side of the car are curved opposite each other, so when the car is rolling forward they function identically. (just like directional tires are mounted differently on each side of the car). This is why the left rotor is a different p/n than the right rotor. With me so far? Now depending on which side of the car you mount the rotor, the vanes could "dig into" the air sending it inwards, or they could fling air outwards. In other words, spin a rotor clockwise and it will scoop up air and send it to the center of the wheel. Spin the same rotor counterclockwise, and it will create a vacuum, sucking air from the center of the wheel, throwing the air outwards. Of course, the rotor for the other side of the car would operate in the opposite manner, since the vanes are pointed in the opposite direction. On your M3, which way are your vanes slanted? Do they move air outwards when the car is rolling forward? Or inwards? I need to know - it's a long story. Don't ask right now. Thanks!

Handy thing to keep in mind: right-side parts end with an even number, left-side with an odd number.

Date: Mon, 30 Jan 2006 21:49:46 -0500 From: kresener@aol.com Subject: RE: Suspension Upgrade Thanks for all of the answers and suggestions, and of course, they've prompted a couple more questions. Couple of suggestions on switching the hats, my belief up to now is that's only possible on the '96+ cars. Couple other suggestions on the Bimmerworld camber adjusting bolts and shims, which sound great, and especially for $25! They're out of stock until later this week, but that sounds like the ticket since the car sees relatively few street miles and is towed for the long distances to the track. I'll be ordering a set shortly. Anyone speak to the difficulty of installing them? Would I gain anything more if I combined the camber bolts and shims along with a used set of '96+ hats? As for my driving style, and possibly going a bit slower into the corners and getting on the gas earlier... I have been accused of being a bit ham fisted in my driving style occasionally! But seriously, whenever I try that I get so pissed out how long it takes to accelerate back up in whatever gear I start to fantasize about forced induction and mucho increased horsepower.... Camber and sway bars are a lot cheaper than going that route! Thanks for all of the suggestions, the list rocks! Kurt Resener Louisville, KY
