No, all you need is a helmet for autocross and it's probably a better idea for your DD than doing track days.

My 2003 NB is randomly losing power, almost like one or two cylinders are dropping out. When this happens it will continue until I clutch in, at which point the revs will drop down to ~500rpm for a second or two before returning to idle and power returns. Does this sound like bad coil packs?

Car has ~170K on it, and original ignition coils. I did the plugs less than 10K ago and they looked good. The power loss doesn't seem to get worse at WOT so I'm ruling out fuel filter or pump problems for now. Any guesses?

Before throwing parts at it, check your grounds. I chased a random drop in power for a long time before replacing the ground here and its been 100% since.

His car doesn't have a ground there. The main ones are next to the throttle body and aft of the exhaust header on the frame rail. Does the tach drop down as well when it does it? If so it may be the cam sensor.

The tach doesn't drop unless I clutch in and remove load and throttle from the motor, if that makes any sense. It'll dip all the way to 500rpm or so and then recover and act fine.

My cam sensor was replaced a couple of years ago, and the symptoms were different. (Hot motor would die at idle and wouldn't restart until it cooled down.)

I'll check my grounds in any case.

SCCA requires a "real" roll bar for soft top. The PRHT has no restriction, which is weird because it's not the hard top supporting the weight. Same with the earlier generations. If you don't have a hard top you need a roll bar. If you have a hard top you don't.

I could be wrong but I think I've read somewhere that the factory roll hoops on the NC don't meet SCCA's roll bar requirements.

Some ERW tubing bent into a U that is 6" lower than your head isn't adequate roll over protection. If you have a hard top, you still need a roll bar because a 50lb piece of fiberglass isn't exactly structural.

That said, go nuts. I'm sure roll over protection is only needed if you plan on crashing.

I'm not actually talking about protecting the driver, I'm talking about complying with track/SCCA regulations. Of course a fiberglass hard top isn't going to be adequate rollover protection. But it does satisfy the rollover protection requirements for the regulations.

If the track is willing to let me out there with the factory roll hoops than I'm willing to take the risk.

You're dumb as gently caress. Have fun dying when the car gets away from you, slides into the grass at 25mph, hooks, and flops over on its roof. I've been doing this for a decade and I've seen that happen over and over. Thankfully no HPDE groups on the west coast are pants-on-head retarded enough to let idiots like you track their convertibles without real rollover protection, so nobody out here dies from rollovers.

This is a real chicken and egg scenario because if someone gets hurt in a roll over scenario on track, the track gets sued into oblivion and closes for everyone.

So thanks in advance for assuming all of the risk for everyone who wants or wanted to visit that track. :v:

E: motorcycle track days put down sandbags and barriers to protect the riders from the track barriers that are not body friendly. If you're riding on the track, you're in full leathers and whatnot so it isn't analogous.

$495. It's a bit much but it's instruction the first half of the day and just lapping the 2nd half. In total I'll be spending more because I'm going to change the brakes first and I need to buy some wheels/tires and a helmet.

I do wish the stock rollbars on the NC were higher, even if they still weren't legit enough for racing. My head is almost above the rollbar and I've been considering the seat lowering mod. The Z4 had much higher stock rollbars.

Are there any good, safe, removable rollbars for an NC? Or does wanting to safely track day a car require you to dedicate the car to tracking? I've read enough about the dangers of rollbars without a helmet that I wouldn't want one in my daily.

The only really decent roll bar for the NC is the Blackbird Fabworx one. It's significantly easier to just have a dedicated car.

For where you're at, I'd just advise you to autocross and get to know the car. Your first few track days have a low probability of going terribly wrong, but if you want to see if you like it and want to pursue throwing money into the fire, there's always the option of renting a seat.

Sorry but you are being an idiot. Savington is right, it doesn't take much to roll your Miata at a track, all it takes is for you to lose control when you start feeling like you're Michael Schumacher, spin out and hit the grass sideways and you WILL roll over. Saying you're willing to take that risk makes you sound like a moron, and you have a right to be a moron if you want, just don't expect to get any support in this forum.

The accident type that Savington was describing is almost comical, too. It slowly tips over and everything. Since humans are dumb as rocks, people will put out their hand(s) to prevent the car from rolling over and will wind up with massive trauma to their hand/arm/ego.

Dude said my intentions of posting was to find yes men when they were really to see what other people who have tracked their car said. I was assuming I'd need a roll bar. The track replied that I wouldn't need anything other than factory, I told the thread that, and said that if the track is willing to take the risk of getting sued (no amount of waiver forms legally absolve them from liability), I'd also be willing to take the risk.

I haven't scheduled anything. I might still get a roll bar. I might not even go do it. It was a loving discussion. That's it.

It's tough love. Tracking your car without a rollbar is a really, really bad idea. I am unironically glad we were able to convince you of that. I've seen too many rolled cars and too many people take a lackadaisical attitude towards HPDE safety to treat comments like "I'll probably be ok" with anything but utter contempt. People die doing this, and it's so easy to NOT die doing it that it's a tragedy when it does happen.

e: In CA, when people die at racetracks, it happens at HPDE events. I can think of four in the last 15 years or so. One resulted in a significant track alteration (ACS), the others can be entirely attributed to subpar or lack of safety gear. Everyone thinks W2W is more dangerous, but the worst thing you can possibly do is go out as a beginner on a racetrack with subpar safety gear. That's why I was so hard on you.
