This is a prickly problem. What was happening that caused this rule was people were taking high end FIA seats and bolting them to stock sliders in T1 cars. You could grab the seat and move it around so much with your hand that it would hit the cage so the back brace rule was added.
Unfortunately history proved we needed to change that, if anyone has a better suggestion on how to make sure only slider installations that are actually secure the seat are used the rule could probably be improved. In the meantime a back brace for seats on sliders is the way we had to go.
A back brace that adjusts when you move the seat is not that hard to engineer but if anyone has a better solution I am sure it would be considered.

We asked for the proper sliders to be allowed that are used in all our Grand Am cars, as well as most every FIA homoligated Porsche. Problem is that the CRB was unwilling to listen and chose to toss them all out. I am sure there is a compromise that can be found and would start with no stock sliders. The competition sliders we use are double locking and allow very little seat movement. We had them in both the GT Mazda's and our Daytona Prototype and I would say they have been tested quite well after some of the hits and roll overs.

My guess is the CRB is unwilling to specify any allowed slider any more than they will specify cage construction because of liability. Sliders are not such a big deal in most national classes because of the sprint format, but are needed in the endurance races. Much more dangerous to have a second driver sitting on a thick pad both under and behind that has them literally sitting on top of the seat with no side protection. We need to find a solution.
 
What steve said. And of course there is no homologation spec for seat sliders - or mounts, so there' sno follow the leader option here. we' seem to be perfectly willing to allow an 8855-1999 seat on any old mount, as safe or unsafe as you wish. but the simillalry non-homologated sliders are verboten. I've written in on the subject, again, and hopefully my current relationship with the CRB and BoD will develope a conversation where previously it was resplied with soemthing like 'thank you but no.'

I'm thinking minimum mounting requirements (hardware, hard points, reinforcment, tie in with cage rules more cleanly, etc..) and wording expressing an understanding that FIA SEATS FLEX (this seems to be interpreted as a problem by many tech officials I have discussed it with OR is understood and poor mounting is excused as a result) and a restriction on position of the seat vs. cage to eliminate flexure into cage members or rerquire back braces etc..
 
What they said. It's been an ongoing annoyance for me, particularly given the half-assed compromises we see at enduros with foam pads and other silliness that leave a shorter driver nowhere NEAR as connected to the seat as he should be.

I feel your pain and do not know the solution but I am sure smart enough people can find one. The T1 problem in my example is real, people got hurt. I do not see the CRB testing individual brands but I have to believe there is a solution.

Geesh...it's been too long since I re-visited this thread. You boys have way too much time and brain power to spare during these winter months. Me in heals? Really?!?! "you're one sick puppy"

so much for correcting errors in the prelims... Some Camarobird 305 errors remain. Note to anyone who plans to build this car, the wieght is 10 lbs high and there is an incorrect brake disk specified, should read 267mm rear. these will be corrected ASAP.

Nice to see that the above car's fuel injection note was added and the 4AGZE displacement was fixed, though.
 
I am thinking of installing sliders to my Sablet Seat. I am wondering if someone on here may have more experience in recomending a specific slider.

I have a Sabelt Taures XL with halo similar to this one here...

I have the following steal side mounts designed for this seat...

And I am thining of purchasing this slider for the seat which I assume mounts UNDER the side mounts between them and whatever I have them ounted to in the car...

Those sliders LOOK exactly like the ones we used on Pablo (originally from Recaro). Your assumption is correct re: mounting. They worked GREAT, neglecting the seatback brace rule since implemented.
