Anyone try GarageStar Seat Rails for FD?
 

The title says it all. Has anyone tried installing garagestar seat rails in their FD? I have a pair of them in my Miata with Recaro SPGs and they fit fine. Wondering if anyone has them in their FD and what seats they are using with it...

I showed this picture from their website to a reputable shop that installs safety equipment and they didn't think it would hold up to much G's. I guess if you don't plan to crash, it will be fine.

I was using them with some Bride Exas III seats.

Also tried to fit some Sparco Evo seats but those seats are too wide for the rails to bolt down

Nice. Do the shoulder of your brides clear the inner door panel or is it touching?

does anyone happen to have pictures of this seat rail with the recaro SPG?

they just barely clear the door. I can take a photo tonight.

^ yes please!

Those look rather thin if they are made out of aluminum..

I have those in my Miata and its thicker than in those pictures.

my initial thought was that they were cheesey as hell if they are aluminum. that won't hold you in the car if you go off course... even if they were twice as thick as that picture, if they're aluminum that won't handle any significant lateral or even horizontal force.

another shop selling crap? tell me it aint so!

well there website says the rails and hardware are made of stainless steel and the seat rail meets all FIA standards for approved material thickness for racing seat rails....

I have not personally seen them but did look at them for potential future use.

From what I have read the FIA states 3mm for steel and 5mm for lighter alloys for seat supports. 8mm minimum hardware size.

Note- this does not imply the Garage Star seat mounts meet FIA standards. This line alone would preclude that.

If rails for adjusting the seat are used, they must be those originally
supplied with the homologated car or with the seat.

ARTICLE 16 : SEATS, ANCHORAGE POINTS AND
SUPPORTS
If the original seat attachments or supports are changed, the new
parts must either be approved for that application by the seat
manufacturer or must comply with the specifications mentioned
below :
1) Anchorage points for fixing the seat supports:
The seat supports must be fixed either:
- on the anchorage points for fixing seats used on the original car
- on the anchorage points for fixing seats homologated by the
manufacturer as an Option Variant (in which case the original
anchorage points may be removed)
- on anchorage points for fixing seats in conformity with Drawing
253-65B.
The seat supports must be fixed to the anchorage points for fixing
seats via at least 4 mounting points per seat, using bolts
measuring at least 8mm in diameter.
FITTING INSTRUCTIONS
1- Drill holes (larger than nut outer diameter) in the bodyshell lower
rail and in central tunnel wall.
2- Weld the nuts on the counterplates, then weld these on the
bodyshell lower rail on the central tunnel wall.
3- Weld the 2 threaded inserts in the crossmember, then weld the
endplates at each end of the crossmember.
4- Fix the assembly through 4 M8screws of 8.8 grade which will be
screwed in the welded nuts.
2) Fixing of the seat supports directly onto the
shell/chassis
Supports must be attached to the shell/chassis via at least
4 mounting points per seat using bolts with a minimum diameter of
8 mm and counterplates, according to the Drawing 253-65.
The minimum area of contact between support, shell/chassis and
counterplate is 40 cm
2
for each mounting point.
3) If quick release systems are used, they must capable of
withstanding vertical and horizontal forces of 18000 N, applied
non-simultaneously.
If rails for adjusting the seat are used, they must be those originally
supplied with the homologated car or with the seat.
4) The seat must be attached to the supports via 4 mounting
points, 2 at the front and 2 at the rear of the seat, using bolts with a
minimum diameter of 8 mm and reinforcements integrated into the
seat.
Each mounting point must be capable of withstanding a force of
15000 N applied in any direction.
5) The minimum thickness of the supports and counterplates is
3 mm for steel and 5 mm for light alloy materials.
The minimum longitudinal dimension of each support is 6 cm.
6) If there is a cushion between the homologated seat and the
occupant, the maximum thickness of this cushion is 50 mm.
All the occupants' seats must be homologated by the FIA
(8855/1999 or 8862/2009 standards), and not modified.
For seats in compliance with 8855/1999 FIA standard, the limit for
use is 5 years from the date of manufacture indicated on the
mandatory label.
An extension of 2 further years may be authorised by the
manufacturer and must be indicated by an additional label.
For seats in compliance with 8862/2009 FIA standard, the limit for
use is 10 years from the year of manufacture.
For Rallies only, seats corresponding to the standard 8862/2009
may be used with supports homologated by the car manufacturers
in option variant.

perhaps they changed the design, because i can tell you that picture is not stainless steel, unless it was painted.
