School me on fixed bucket seats and mounting solutions!

I get it, but if it was that big of a risk would they let you option a GT3 etc with one?

Those are interesting in general. To function as an roll over safety devise, a roll bar should be no more than 6" behind your head. This is why it's important to have a cage/bar built specifically for you, if you go that route. On a seat with 12+" of slider travel (E,g, the GT3 clubsport), that's clearly not possible to consistently deliver.

My guess is that they put them far enough back that they're not a safety issue with a 3 point, which makes them not super effective as a roll over safety device-- so their primary functions may actually be chassis stiffener and harness mount.

idealistically, I get it.

but cage design is also chassis dependent to determine pickup points. as with everything else, it's always a compromise. your point about not having the main hoop too close to the seat for street applications is valid.

If you have a roll bar then I would have fixed back seats. Back brace is recommended.

I would never use recliners and a roll bar.

A 996 GT3 went backwards into a tire wall. Both OEM Recaro recliners broke and the driver and instructor hit the roll bar. They went to the hospital...not life threatening but don’t think a quality aftermarket recliner won’t break.

Likely stock seats, as well. There’s no mandated test for seats with regards to going into walls backwards, so any design for that is strictly voluntary by the car companies (unlike based on my company— we don’t test for that at all, and make seats for some OEs).

A roll bar without a seat back support is a safety downgrade going into a wall backward for sure, regardless of seat. With a seat back supports, it depends how crumpled your car gets— if the area with the roll bar gets compressed, the roll bar is coming into the front seat.

The BK mounts let you run the stock belt receptacles. If the 3 point will be snug to your body depends on the design of the seat.

Yeah, Im now thinking the Recaro PP might be the least ideal seats for running the factory 3 point since the harness holes are pretty high up (like on the SPG as Sharocks mentioned), but also pretty small (so most likely cant pass the buckle through to the receptacle outside the seat) and will prob jab into my hip like you mentioned in your write up. And Nagaros are unfortunately outside of my budget in case you were wondering why Im not considering them.

So another seat Im eyeing for this reason is the Cobra Suzaka Pro-Fit, looks similar to the other seats I listed but the side holes seem not only much bigger (that a 3 point buckle could fit through), but also seem very low to the bottom cushion, so hoping the lap belt can sit snug, compared to the Recaor PP/SPG or Sparco EVO QRT. Unfortunately I dont have access to any of these seats to test out in person, Im just going off pics on the respective sites, and there's not even many or hi-res

I run the Cobra Nogaro Circuit and really like it for a weekend car. Definitely not if I was daily driving. It's not the cheapest, but it looks great, can use BMW rails, even powered, and the factory lap belt isn't super sketchy.

A good fixed back seat to run the stock 3pt seatbelt is the Recaro Pole Position ABE/TUV version (Europe only). The hip area is a little wider and indented to accommodate the OEM seatbelt receptacle. If you looped the seatbelt on one side through the belt hole, you would have a much better waist restraint. The lap belt would no longer be resting on the side bolsters but rather directly on the occupant's body. This seat is similar to the version found in the M4 GTS which is OEM in Europe.

This ebay seller has them available: https://www.ebay.com/itm/RECARO-POLE...ff08%7Ciid%3A1

You are the MAN! Thank you, this is just what I was looking for my situation! I wasnt even aware of the ABE/TUV versions were for road car and 3 point use, they seem to be perfect for my application! And extra thanks for the ebay vendor link since they're not available in the US (surprising considering we're usually wider lol). I'm eyeing the black velour pair he has, price is very reasonable too even with shipping from Germany!

So I can get the BK fixed mounts for the driver, but for the passenger are the BK 'Seats mount to OEM slider' so that I can mount a seat and still retain power sliding? Dont care for powered or manual, just want to be able to slide the passenger for rear seat access and convenience. I was considering the VAC seat mount kit w/ slider for just the passenger for this reason (even though its quite pricey IMO).

Correct on the above about the BK mounts.

Happy to help! I've gone through a multitude of different seat mounts, BK is the way to go. OEM sliders have way more adjustment range than any aftermarket solution, they're also more solid. I wouldn't even bother with VAC.

[bigjae46]

The VAC sliders won’t allow much access to the rear seat...they are mostly useless.

I use the mounts from Burkhardt Engineering for mine. Seat sits low, that's what I care about.
If you need the rear seats, I think the oem csl mounts are the best way to go since the allow folding. Although the part numbers seem to be no longer available...

The CSL mounts also only work for seats the dimensions (width) of the csl seat and are probably the mount that goes the least low.

That's why I did not use them, I want low :-)

But isn't the csl seat a Recaro PP? They closed the holes for the 6 point, but the basic shell for the mounting holes should be the same? I cannot imagine Recaro made a special tool for some low quantity CSL...

It’s closer to an SPG— 390mm wide (pretty narrow) at the mount points. The pole position is 430mm wide at the mount points (pretty wide).

If you REALLY want to get low, nothing let’s you get lower than the BK direct to floor mounts. You can compress the floor carpet with the bottom of a recaro seat with their direct to floor mounts.
