G87 M2 - track safety devices
Hey Guys,
Does anyone have experience with installing 6-point harnesses on their factory carbon buckets? It seems like they're fit for them, but it's not clear and there isn't much info online. Which rollbar works best with the G87 for harness mounting? Any info would be much appreciated. Thanks! |

I've looked into this and I don't think there are any 6-point options with the factory carbon buckets.. best I could source was a 4-point that either uses factory seatbelt locations, or half cage/ harness bar.. I'm using the Schroth QuickFit Pro 4-point from the E92 M3, because I still occasionally use the rear seats for my kids, so can't install a cage or harness bar.

The quickfit pro already has the slot in the rotary buckle to upgrade to a 6 point. You will obviously need to have the seat base modified (cut & sewn) to suit (if the silly carbon insert piece is removable that may be an option).

yes, they do have the allowance for the addition of sub straps to make them 6-point, but that would mean cutting the factory carbon buckets to make it work.. think I would rather install aftermarket buckets if I get more serious with track duties

I would be wary of that setup. Schroth told me not to use their quikfit pros in the M2. IIRC, the angle of the rear straps is too steep which could result in severe injury.

It's the same angle and install points as approved for the E92 M3, only difference is the G8X carbon buckets which are yet to be tested by Schroth, hence why not released specifically for G8X. I've taken that risk as the only option on-market that clips in and out easily, without installing a roll cage/ harness bar that renders the rear seats useless.

they're also approved for the cobra nagaro and recaro pole positions so gave me more confidence, considering the closer designs to the G8X carbon buckets

Schroth Quick Fit & Quick Fit Pro Video
Here's more info on these models.
Schroth will not certify their belts for a specific model without specifically testing them on that vehicle. That said, I used the Schroth Quick Fit model on my former '19 230i xDrive for auto-x and several PDEs. Great improvement in holding you in place. I don't believe the seat setup is significantly different in current 2 series...but as they will tell you, use at your own risk. |

That would be entirely dependant on what seats they were talking about… the stock seats are obviously going to have a different angle to the carbon buckets. The general rule in motorsport regarding safe operation is a 45 degree max angle.

I'm working through this on my F87 M2 with HMS Motorsport. You will likely want a removable harness bar with the Profi II ASM harness. The harness bar positions the harness to eliminate the seat structure risk, and the ASM reduces the risk of getting pinned upright if the roof collapses.
If you want to avoid a harness bar, the only "approved" solution is the Rallye 3 ASM. With the Quickfit Pro, you're assuming that the seat structure, hinge mechanism, and buckles are all designed the same or better than what was tested. It's likely to be OK, but an unknown, and not something I would personally want to be a guinea pig for to save $1,000 on a harness bar and a little time for car setup.
