I have a 92 miata, which I think would be a great car for getting me used to track days. I am not sure what I need to do to get started though. I know I need a rollbar, and I have been reading through NASA's GCC, whiCh seems to be for both HPDE and solo comp. I am just interested in the HPDE right now and am not sure what I have to do to my car just for hpde.

The GCC talks a lot about seats and fire extinguishers and all this other stuff that I am not sure applies to me. Yes of course I can never overdo safety on the track, especially in a 23 year old car. However, I think it would be better to take this step by step, rather than try to fit everything all at once before I go.

So what (besides rollbar, looking at a hard dog m1 double diagonal for that) needs to be done to meet the bare minimum requirements? My battery is tied down securely, my engine doesn't leak anything, my wheel bearings are good (one of the front tierods has a very small amount of play, will probably change that out), suspension is good, and the seats are stock with stock belts.

This is an eventual plan and will probably not happen until next year sometime... but I want to start planning things now.

Thanks

I'm not sure, but I think anti-freeze is a no-no. I had "water wetter" in my car when it was on the track.

I've got the same car and planning the same thing. So far I've taken it out at VIR once in a "Hyperdrive" (abreviated HPDE 1 event - instructors in car - 30 min - no passing). They had no problem with a 100% stock miata + a hard dog hard core double diagonal roll bar.

I've attached the HPDE tech form that NASA uses. A buddy and I teched ourselves for the day. When we got to the track, our instructors went over everything again with both of us in the paddock before we went to the classroom session. It was slightly more intensive then the tech that goes on an autocross but not by much. I had my own but there were loaner helmets around. Long sleeves/pants/close toed shoes required.

Moving forward I plan on upgrading to stainless steel brake lines, some better pads, new shocks, and work my way up from there.

Almost all of the HPDE events I have attended have been PCA.  (I have done NASA
autocross but no track events.)  PCA does an excellent job making their events safe
and fun.  In fact six of us just had a great time this past weekend.   Grin

Here are a couple of threads with more info, to give you first-hand impressions.

Registration link for this year's September event.

These events really do fill up fast, so if you think you might be interested then don't delay.

I try to do at least one HPDE a year, unfortunately money and time constrain it to that for me. I would say the biggest and easiest improvement you can make for a track day is switching out your brake fluid to DOT4, this will reduce your likely hood of boiling the fluid and ending your day early or becoming frustrated with the car.

Another thing to keep in mind, pick one organization (PCA, Trackdaze, NASA, FATT, etc.) and do as many events as you can with that club. The records don't normally cross over, so if you were in an intermediate group for one club you may be put into the novice group for the other, which also leads to lots of frustration.

For most clubs, you should just need the rollbar because it's a convertible.  Depending on the club, you may need some arm restraints if you don't have a hardtop.  You'll want to change all your fluids, including a brake fluid flush (as stated above, DOT4 is the way to go), and make sure the caliper slides are well lubricated.  You could run coolant in your car at all the HPDEs I've ever been to, but everyone has slightly different rules.  When you find a club, just shoot them an email.

Thankfully, Miatas are pretty easy on consumables.  On our LeMons car, we were running the cheapest rear pads with the cheapest rotors all around, only spending some money on front pads - and the brakes tended to last around 50hrs of track time.  At Miata speeds, you really don't need a lot of braking power Smiley  We were running whatever decent decent brake fluid we could get our hands on easily for not too much money (ATE Super Blue/Type 200, Amsoil DOT4, Wilwood EXP600).  We also ran good motor oil (Amsoil Dominator).
