FIA adjustable seat mounts
So far as I know it is not possible to use an adjustable seat frame as none are approved by the FIA.
Is that correct ? I am hoping I am wrong..... Alex |

No, that is correct. Seat mounts have to be solid.

I have seen adjustable seats in race saloons over the years but they "should" have a positive way of locking them (ie nuts n bolts) into place but they are not always picked up in scrutineering, however the time taken to adjust them officially would take too long and wouldn't be any good for a driver change in a two driver race. The bolster cushions for the shorter driver seem to be the only legal way.
Personally I don't see why a seat on decent designed sliding runners isn't allowed in car races, track days seem to use anything and it's the belts that hold you in after all ! |

As always, it depends - on where you want to race. Yes you are right under FIA rules e.g.Spa 6 hours, but at National level adjustable seats are fine - as long as the manufacturer's original seat base and runners are used (I think it's implicit this only refers to race-prepped road cars).

That sounds crazy. The seat in the Ferrari that I drove in the Intercontinental Le Mans Cup last season had a seat on a runner. So did the Audi I drove in the Dubai 24 Hours last weekend. Most modern GT cars seem to have them to allow for drivers of different sizes. Also, it aids entry and exit from the car - with the big "ears" on the seats around the helmet area and the limited door opening area, a fixed seat can make entry and exit a big issue.
Crazy if this is no longer "legal". |

My take is that the FIA say aftermarket adjustable (sliding) runners are NOT allowed. But may be some obscure reg somewhere that says car manufacturer fit are allowed? Could be that they view a production car based formula differently?
For UK seems OK to have sliders- aftermarket or original- but the locking catch must operate on both slides, and of course the seat mustn't tilt or hinge in any other way. |

Might be wrong but I always thought that runners of the double locking type were perfectly compliant.

It must reach a point where loading a seat with cushions is far more dangerous as the driver is then sitting on the seat, not in it.
I suspect that at one point they allowed the manufacturers seat mounts, much like they allowed standard fuel tanks, as they know they would be TUV approved etc & so known to be up to a certain standard. Some Gp A 635`s had the standard seat mounts fitted. It is a problem when there is 12" height difference between drivers ! Alex |

I think it's just that they haven't been sent for homologation. Like everything else seat mounts are subject to FIA tax. IIRC there's a set of OMP adjustable seat mounts on the Market that have been homologated. Think they were pretty pricey.

But they would looking for an FIA label, which they don't think would have been affixed in the first place! |

Well spotted! First time I have seen the phrase- 'FIA Approved When Used With Recaro FIA Side Mounts' used!
The item is hidden (p153) in DT's printed catalogue, which is disappointing, and perhaps indicative of changing times..... FIA 8855-1999 is referred to. Here is LINK to the pdf- Enjoy, it's only 27 pages.... |

Well I invested in a set of Recaro ones today (I already run with a Recaro seat and mounts) and fitted in a couple of hours, dead easy. Should make endurance races easier...
I'd interested to see what scrute will be able to see that they are FIA approved without climbing under the dash of the car with a miner's lamp. ...I'll glue the receipt to the dash I think. |
