Driving track on stock MSport seats
Aside from the sport seats beinglimited in terms of bolstering and keeping the driver in place during high speeds, the head rests get in the way when wearing a helmet and a neck restraint system. My question is what do you guys do to rectify this?
1. I was thinking of just removing the headrest, will this decrease overall safety since the system is meant to work w it on. But is it kind of a moot point since a head and neck restraint system is being worn already? 2. If I remember it right, you can’t put a race seat on and use stock seatbelts as it is illegal in NASA or any other association for that matter. Correct me if I’m wrong. |

I take the rear seat headrests and put them on my my front seats when at the track. They will go down most of the way and are thinner providing some extra helmet room.

The sport seats (in the M-Sport package, IIRC) are miles better than the base 128i sport seats, so be thankful you have them as standard.
Try doing the seatbelt lock trick (below) and using the rear headrests up front. For the seatbelt trick, slide your seat all the way back, fasten your seat belt. Give the upper belt a strong yank so that the reel locks the belt, then hold it against the lock while sliding your seat up to your normal driving position. This will hold you back in the seat in corners and really helps with hard braking.

I seriously contemplate getting buckets for the two front seats only for when doing track days and revert to factory when not. Although w the car being parked most of the year, doing that switch is pointless. But anyway, anyone know if having buckets but using three point belts is allowed for HPDE? I’m riding w NASA mostly but wanted to know if this passes tech. |

Have a look at a CG lock if you want to use the 3 point belt.
Not sure if that would pass tech inspection but it worked well keeping me in place on leather seats during track events. |

I’m still not quite at your level of going REALLY fast but do feel that I could do better in the seat department. When you say harness, you meant a harness BAR (cage?) correct? I understand it is a big undertaking. I’m sure there are harnesses(cages) out there that are reversible (screw on to floor pan) if you do decide you’re done w it, although I’m sure that’s very rare or probably discontinued for our cars at this point. Being in HPDE only, what I’m thinking is probably overkill. I MAY try to be at the TT level w NASA but not much beyond that for now. Just want to be able to get more out of the experience that’s all. I know bionicbelly did NASA TT5 and wanted to hear his thoughts as he also drove a 128. I was thinking though, if a car came from factory w let’s say the BMW perf seats, which are basically Sportsters, if I had those on combined w a three-point, will that still be legal since these seats are offered from the manufacturer? |

I haven't had an issue with buckets and 3 points at NJMP or WGI, with PCA. I can't say what LE's take is at Millville, but I haven't had an issue with them during two different traffic stops with two different departments.
NJMP does not permit 4 points, iirc. TNIA does not permit 3 points with aftermarket seats. However, there are even some time trial groups that do not restrict buckets to 5/6 pts.

I think there are two different discussions here: 1. There are fixed-back bucket seats, which is when you have to move to a 5/6-point harness and rollbar/half cage. This is certainly the safest option but also makes the car more dedicated to the track. Or 2. You can install an adjustable-back seat, like Recaro Sportster, which can still recline like a factory seat and has the provision at the base where the 3-point lap belt can correctly pass over and hold you in place.

I was at NJMP 2x last summer and the track was doing full vehicle checks. They took brake fluid samples from literally every car too. Several people with some pretty nice cars got sent away. Just speaking from experience. Can't say anyone elses experience will be the same. |

Rules vary from club to club as does how strict they are at enforcing the rules. Some tracks impose strict rules on some clubs more than others. It's something for OP to research. |

Yeah, 3-point in my mind means factory seat belt. You're right, it's up to what the club wants to enforce.
I've done track days in my E36 with stock seats/belts, aftermarket adjustable-back seats/factory belts, and fixed back seats with 6-point harness, no one has ever said anything to me, positive or negative, about any of those setups when going through tech. But I also haven't been up to any of the tracks in the NE.

Thanks to all the replies. I did mean the factory seat belt with the 3-point. Sorry for the confusion.
I agree that it is indeed club-specific. I ride w NASA NE mostly but also with PCA North Country and COM here in Mass. I’ll reach out to them and see what they say. If the BMW performance seats pass, does that equate to Recaro Sportsters passing as well since they’re basically one and the same? Just because I think that’s the closest to getting better side support but not going to a full fixed back seat. |

There may be different rules from club to club and track to track but the fact of the matter is very simple: once you touch anything safety related you better go all the way to a system designed to work together.
All this talk of fixed back seats with three points and various combos is making my skin crawl. Once you go to a fixed back seat you NEED to have roll over protection, which means you NEED fixed, six point harnesses, which then means you NEED a HANS. There is no way to mix and match and come up with a solution that's as safe as stock, or fully fixed. In the event of a wreck you need to either move in a way the way car manufacturers have spent billions perfecting, or make sure all of your parts don't move. The only exception I, or the club I usually run with, makes is Schroth quick fit harnesses in an otherwise completely stock car. |

Thanks for your response. I am particularly interested in the Schroth Quick Fit harness. I have always heard of it but NEVER knew that it could work for an other wise stock car like mine. I think this partly solves my problem. I have emailed NASA NE and still have yet to hear from them. |
