As posted by others in terms of equipment, brakes are what you need to pay most attention to for any trackday event. It's always best to bleed the brake system with fresh top quality brake fluid just prior to and immediately after trackdays. My AP 304 mm kit came with DOT 5.1 fluid (compatible with DOT 4). Not to be confused with DOT 5 which is not compatible.
Ferodo DS2500 sounds like a good choice since my Formula Renault uses Ferodo race pads. I will be getting the DS2500 for my
MCS rear stock calipers with grooved disks to complement AP 304mm fronts.
I also suggest you observe cautious driving technique. For instance, take 1 warm-up lap, then for next 5 laps start at say 80% driver/car capability, then progressively ramp up to 95%. Then take 1 cool down lap quite slowly with minimal need for braking. This will give your engine and brake disks a chance to cool down. Once into the pit, as much as possible try coasting to a stop without brakes so the pads don't stick to disk and possibly cause disk warpage. Once car come to stand still, DON'T use the parking brake for the same reason. Just leave car in 1st gear.
By doing 7 lap instead of say 15 lap per session, your car will undergo far less stress. Besides, it will give you a chance to sit down between sessions and think about the braking, turn-in, apex, and exit points to improve for the next session.
It's very hard to resist the urge to go hog wild as soon as you get on the track, but believe me a full day at the track is infinitely more fun than having your day cut short by mechanical breakdown or getting caught in the gravel traps. I have seen too many accidents at trackdays where drivers do serious damage to their cars and themselves by getting too eager too soon. Don't mean to preach; it's just my observation.
If you are planning a track day at ZIC, PM me and I can give you some pointers on the braking points at ZIC. I am interested to take my
MCS to ZIC too, do you know if there is any scheduled ZIC trackday for Minis coming up? Good luck.
