I'm afraid I have nothing to do with tech inspections at Eagles Canyon.
That said, I will be sharing the track with you, so your safety affects my safety. If I notice something on your car that I don't feel is safe, I won't hesitate to point it out.
Here's a quick track day checklist:
- Brake pads - Make sure you've got plenty of brake pad left. Minimum half pad depth.
- Brake fluid - Should be high quality and reasonably fresh. I'd recommend Valvoline Synthetic at a minimum, and Motul RBF600 for heavier cars and more advanced drivers. If you haven't flushed your brakes in the last year, now is a good time. This will also give you a chance to do a visual inspeciton on pads and rotors.
- Tires - Tires should be in good shape (no cracks, no leaks, no plugs) with 2/32nds minimum of tread remaining. Bring a compressor if you've got one.
- Coolant - If you can't remember the last time you flushed your cooling system, now might be a good time. Miatas have marginal stock cooling systems to begin with. 25 minutes at WOT puts a lot of stress on this system. I recommend a 30/70 coolant/water mixture.
- Oil - fresh oil is cheap insurance. If you're close to a normal oil change interval, you might consider doing it before a track day instead of after. Also, several people (myself included) have burned up Miata motors due to oil starvation. I'd recommend over filling by about a 1/2 quart, just to be on the safe side.
- Interior - If you live out of your car, now is the time to clean out all of your crap. You shouldn't have anything loose in the cockpit, and you should remove your floormats. You'd be suprised how much loose stuff flies around inside the cockpit on the track. I had a student once who had left a roll of paper towels wedged under the back of the passenger seat in his car. The roll came loose, partially unrolled, and about a dozen sheets ended up flying out the driver's side window before I managed to grab the roll and secure it. Things like this do not make for a comfortable driving environment.
