Anybody running Recaro Pole position seats on sliders in a 911?

[nippy]

If so what sliders are you using? I have a 86 930, any help would be great. Wanting to use the side mount recaro mounts and a slider.

[Bill Verburg]

use Recaro or Sparco sidemounts and sliders
looks like this

the aluminum versions are far easier to work w/ than the steel and either is easier to work w/ than the BK

So recaro sliders?

Ive seen the steel side mount readily avail. Must the be for Pole Position seats only or any Recaro? Also could you point me in the direction to get the sliders? Model or or style #? Seems to be a bunch out there.

I run Recaro rails with Sparco sidemounts:



Earlier also with Recaro steel mounts:









And yes, drilled (for those who know me...)

I don't use sliders but just want to add that on my 86, with the Recaro aluminum side mounts, combined with Recaro Pole Position FIA, that you will need spacers to fill the gap between the mount to the sides of the seats. I used to use the Recaro steel washer type spacers before but do not like them as it allowed the seat to wiggle side to side too much, and I think it also concentrates too much stress load at the seat's bolt points. Instead, I fabricated spacers from black cutting board plastic (HDPE) which eliminates the wiggle and completely stiffens the seat mounting in addition to distributing the load over a larger area of the seat's surface. If you use the Recaro steel side mounts, they are bent with an offset to not require spacers. Also the Sparco aluminum side mounts are bent with an offset like the Recaro steel mounts, not require spacers and match to the Recaro seat bolt holes too, though the upper most mounting holes are maybe 0.5 to 0.75" lower than the Recaro aluminum's. Since I do not use sliders (for a 12 lb weight saving), I use the higher mount points.

Thanks everybody this helps allot. I have factory sliders, starting to think I should buy aftermarket sliders?

Factory works great.
An extra hole drilled in the brackets and Bob’s your uncle.

So I can run the recaro side mounts and factory sliders? This is the seat by the way and the project 930 race car.

Turning this 930 track monster back to a street car "project"

I have Recaro SPA on recaro brackets mounted on factory sliders.
I drilled one hole in each bracket to make them fit, that’s all.
Works great.

I know, car’s dirty…

The 3mm spacers Steve W alludes to are necessary if the RS inner buckle mounts are used

3mm spacers


slider bolt washer on left RS inner buckle mount on right,








another issue will be the height and angle of the buckle, I use SPGs with higher bolsters that aggravate the issue, so I used rear receptacle through the side hole, w/ PP the stock one can usually be bent enough


another alternative is Southbound Trimmers which have the buckle mount integrale to the side like the newer GT3s

I went with the Steele black side mounts so that we didn't have to use the spacers. These will be mounted on factory sliders. We're also running Simpson 5 point harness with the seats. I know we're paying a weight penalty but the owner is not concerned with it. Thanks to everyone that chimed in.

You won't want to attach the harnesses to the seats
on the door side use eye pads in the original door sill position




and bolt a pair of eye pads in the tunnel area





This from Schroth show the way the harness belts have to run, the issue that we have run into w/ PP is that the seat shoulder harness holes are too low and small for taller drivers, to allow a straight fetch at an acceptable angle to the shoulder



here you can see the shoulder mounts through the hole in the SPGs, you want the cross bar as close as possible to the shoulder w/ no contact to the seat

Thanks Bill

Technically sliders are not legal for many racing organizations with racing buckets. However if you're using the sliders from the factory manual seats, those are even less safe because they only lock one rail, leaving the other one to slide and present fore and aft shear loading on the side of the seat with the fixed slider, concentrating a lot of load on those two fiberglass bolt points, which for a seat that formerly had a recall by Recaro due to due to non FIA compliance for mount point failure, is not the best idea. Imagine what could happen in a crash which could present a high g-force to the seat, such as if the back of the car slammed into a wall. Better to use aftermarket Recaro sliders that lock both sliders.

Actually, while Bill is right that when the RS inner bucket seat belt mounts, because they go under the rails, you need to space the other three points of the seat equally, which I fabbed out of some aluminum, the spacers I was referring to are the ones circled in red in the picture below. The seat rails on the 911 (at least the g body cars) are spaced such that with a straight vertical upright such as the Recaro aluminum brackets, the uprights will be something like 1/2" too far away on each side of the seat to bolt up. Recaro provides these fat steel spacers that look like a thick 3/4" washer to make up the gap, but as mentioned, they allow the seat to wiggle too easily. The spacers below circled in red completely eliminates the wiggle and is a much stronger mounting solution. The alternative is to use the Sparco aluminum or Recaro steel mounts which are bent inward.

Ok thanks guys. I have purchased the Steele Recaro mounts. Im supposed to get factory sliders Monday from a local Porsche parts guy. You can see my car here. I guess my question regarding the double locking sliders from Recaro is do they just mount onto the factory slider mounting pods that you can see here on the bare floor boards or do you need to fabricate something?

Or is the problem running harness with seats that move forward/backwards?

No racing in my car, strictly street.
But strong argument. Double locking would be better.
