First Time at the Track - Dark Horse - Road America

[BimmerDriver]

I don't think any instructors are given for Track Night in America events. Just a little more instruction before and maybe a pace lap.
So this is not my first event , first in Dark Horse. But over the last 5 years I've only done a couple so I'm still green.
Do I really need to change the Brake fluid if I'm not going balls out? Stock fluid was fine on my Mach 1 wen I did Blackhawk.

Absolutely yes, change the fluid! Unless your car is less than 6 months old, flush that old fluid. RA is a very fast track and you will heat up those brakes. Cooling down is not the issue, the issue is that the brakes get very hot and if there's water in the fluid (which happens just from age) it will boil and your brake pedal will not only get soft, but you'll lose some braking ability.

It's what we call cheap insurance. Why take a chance?

Cars got 9k miles on it, been flex tuned for 10 months, no issues (knock on wood)

What fuel do you plan to be using on the track?

Map out the closest fueling stations. Show up with the tank topped off.

On my Dark Horse, one session is roughly half a tank of gasoline, a little less. That is on 93 octane.

On E85, it will be more. The higher the ethanol content, the more fuel you will use per session.

Fuel at the track is like a bazillion dollars a litre.

Ok, I will definitely do that. I'll have a full tank of 93 in the car before I leave to drive up there so the tune will be fully learned over to 93.
So you don't think I'll get 3 - 20 min segments out of a full tank?

Do you know offhand the recommended Motorcraft brake fluid for the Dark horse and how much to buy?

The specification should be in the owners manual... I think most guys are going with motul or redline for track use.

Would you use either of those for daily road use or instead swap out after the track day? If it makes any difference the normal air temps here are on the high end…

How simple is it to bleed and refill?
