lots of awesome cars! that yellow 355 looks amazing.. the cobra technologies in the M3 are the Real Deal!
What power steering fluid (ATF) do you run? I switched over to Redline D4, and the fluid can withstand a whole lot more. It still heats up a lot, but the factory fluid boiled in a couple of hot laps. The Redline stuff at least lets me enjoy the car a bit when it's warm out.

Favorite Quote: "Understeer is when you hit the wall with your front end. Oversteer is when you hit the wall with your back end. Horsepower is how hard you hit the wall. Torque is how far you move the wall when you hit it. "
Do you do a lot of drifting/snap oversteer on the track? I find power steering fluid not to be a problem on faster tracks with limited bends.
Nope, just clean driving. My home track is a 1.4 mile circuit with a much tighter feel. A few hairpins and sharper corners. My first time out was in the winter and everything was awesome - then my first time out in the summer I got three laps in and my PS system boiled over. I am running on square star specs, but I suppose the tighter nature of the track is the main thing. I could see that on a higher speed track with more wide sweeping turns it may not be as much of an issue.

OsinO - great post - thanks for sharing.
I see Trillium BMW Club of Canada is putting on another School at Mosport September 7-9 2012.
I'll be registering for that one. Hope to see you out there.
With respect to power steering? Yes - the resevior cap o-ring does help prevent splashing from boilover.
I run the 275 square setup and at Watkin's Glen I had PS failure with grippy RE-11's.
I ran the 245/275 at Calabogie - I had PS failure with Nexen N3000 tires.
What I think is a problem is the long sweepers put huge loads on the PS system which has insufficient cooling.
Eventually it gets to a point where the fluid boils, then no more power steering.
For me - I have regular ATF - soon going to put Redline Synthetic in - see how that works.
My guess is it is right on the boiling limit with regular ATF.
Every time I've been on the track I've lost power steering for certain sections. Keeps you awake anyway!
Brakes with the stoptech ST-40 355mm front and stock rears on PFC-01 pads with either Motul RBE600 or even ATE type 200 have never been a problem.
Jacking from the rear diff?
I really like the idea of this product - jackpoint jackstands - But the price of $299 to $349 is what kept me away.
Seems to be about the safest way to lift and support the rear of our car using the factory jack point.
Problem I find using jackstands for the rear while jacking each side up is the amount of stress put on the jackstand as it is only intended to take a normal (up/down) load - not a side load. I've seen my floor stands get up on two of four legs as I'm jacking the car up - which to me is asking for disaster.
