I have a set of quickfit pros that I'm hoping to repurpose for the M.

I'm pro "no harness without a roll bar".

You need a proper seat for a harness, and at least a harness bar in back for proper shoulder belt attachment.

I'd say stick with the 3-points unless you are building a track car...

Appreciate the advise. I already have harnesses in my other cars and am looking to fit one in this car. I have one left from my 1er and wanted to check on mounting points.

GSR, now sold to another shop, had designs for a bolt in (Non intrusive) roll bar. look up their 228 project.

Belts DO HAVE expiration dates.

You shouldn't really use belts w/o a proper installation, e.g. roll bar.

That said, in the past some people have bought or salvaged extra buckles and attached the belts to those and clipped them into the rear seat belt clips. Hope that makes sense.

EDIT: I was under the mistaken impression that the Schroth ASM technology was the between the thigh anti-submarine belt. Turns out after talking with them, the ASM "energy converter" is stitching in the one of the shoulder belts that on impact rips and allow the body to rotate like a normal street belt and would therefore allow your head to move out of the way of the roof, etc., if needed.

Wish they would explain this better on their web site b/c I would have been using their belts long ago.

Harnesses should not be used unless installed to a proper rollbar. I've used this in both HPDE's and Autocross events for many years. It works amazingly well. http://www.cg-lock.com/

Interesting that I'm an outlier here in using a harness that was designed for no roll bar. I am not interested in a roll bar for my daily driver. Quickfit Pro 4 points were designed for people like me who are looking to be held in the seat better than the stock belts and also give a higher factor of safety than the same. Perfect for an HPDE.

Also fascinated that there is a recommendation for a simple lock on the stock belts vs the 4 point.

Oh well. Thanks everyone for the input. I'll search elsewhere.

Did not mean to offend with my suggestion. I suggested the GC Lock as it does keep you firmly planted in the seat. In the unfortunate event of a crash, your stock three point harness will protect you better than the Schroth belts if the rear attachments of the Quickfits aren't mounted at shoulder level or at a shallow angle lower. Connecting them to the rear seat belts down low can be at an unsafe angle. Just trying to help.

Quickfits are designed to pass through the headrest and mount to the rear seat belt mounts. So no issue with the shoulder requirement. Before I got the quickfit I simply put my seat way back, snapped the belt lock, and then moved the seat forward. It worked well. The Quickfits are much better though.

People who tell you not to use the harness do not understand the quick fit system. Head over to 2 addicts and I have a post with them installed under the track section.


SCHROTH street legal harness belts are unique in their ability to be installed to factory provided mounting points along with the factory provided seat belts. SCHROTH harness belts meet all certification requirements by the German TÜV, ECE-R 16.04 and US-DOT FMVSS 209 for use on public roads.

The whole point is that they do not allow your body to move out of the way. The fact that they are street legal and certified doesn't matter. If your roof is crushed your body can't move out of the way.

With Front end collisions submarining is also an issue.

I know this will inevitably get asked, so I'll do it.

Would the BMW Performance Sport Seats fit?

Seems like the consensus is that the stock belts are better than the quickfit pros and that a roll bar is the only alternative. I was hoping to get input on my original question and not on the relative merits of the alternatives. In hindsight I probably shouldn't have posted in the first place. I'll just look and see what seems best. The rear two points as well as 1 of the front points are already defined and work. Just need to look and see what is best for the outside front mount point. When I posted I was hopeful that someone had already sorted through it. Appreciate the feedback.

BTW this is what I have:

Firstly, submarining is not an issue with the right seat, belts and mounting points.

I rolled a car when I was 18-years old - two rotations in a little Fiat Uno. To think you can intentionally move your head out of the way of a roof being crushed is naive. You are being chucked around in the car by the violence of the accident.

Despite my own experience, a car rolling is extremely rare. And I've done plenty of trackdays and been to many motorsport events. Sure, it does happen, but not often. It's also pretty rare on the road - outside of SUVs rolling over because of their high centre of gravity.

A harness will keep you secure in the seat and reduce injury in all of the other accidents you are likely to have. In the super unlikely event a roll-over that crushes the roof enough to impact your head because you are in a harness you're probably screwed anyway.

I'm not saying it's a bad idea to have a roll-bar, just that a proper seat and harness is still a good safety (and driving) upgrade over a normal seat.

A four point belt doesn't really help submarining. You need a pass through to help with that. There're some nice alternatives though. I realize the exceptions and benefits to a nice setup. HPDE brings exceptions, especially for a street car. So I completely understand wanting one.

I didn't mean you intentionally move your head out of the way. If a roof is crushed the roof moves your head. A three point allows that downward movement. A tight harness doesn't.

For auto x I see no problem with having a seat and harness setup. For large tracks I do. I just don't want to see anyone hurt. In no way do I know it all. I'm just repeating what Ive been told by the racer/drift crowd I know, Along with research I've done. If a drifter tells you it's a bad idea, it's probably a really bad idea hahaha
