Does anyone have a good link to designing an auto racing seat shape/dimensions? Usually it is the padding that is custom tailored to the individual driver so I’m thinking I can make a mold that is one size fits most all drivers/passenger.
Also how would the upholstery guy attach his leather to the seat without covering up the pretty carbon fiber back and a few key areas of carbon fiber showing on the front side?
Doh! So it’s not a real “racing” seat!
Yeah, real racing seats are CF shells with blocks of shaped foam velcroed on!
We have a seat shell that is made in Japan. We recover them in Alcantara.
tahhahaha not full time anyhow… probably guys who do track days would buy it. It will be finished clear coated cf. It is up to the buyer to decide if they want padding and where to place it.
I don’t even know if I would “upholster” them. I like the look of just foam padding strategically placed and then covered in cloth just on the foam.
Those are nice 1offnsx 
I like that alcantara material… my upholstery guy i know does that type of work. Now that i think about it more I do not think I want full upholstery done on the seats i make… just foam padding. If the customer wants upholstery i’ll just add 20% cost to what my guy charges me for the work. 20% pita charge lol.
I will have to buy a lot of urethane foam to build the plug:o
Any ideas on plug construction for such a seat?
Also where the heck do you buy those plastic seat belt inserts? Or should I go ahead and mold those out of carbon fiber also?
Are you planning on getting them FIA approved? Ours cost quite a bit to get certified. Upwards of $10k. If your going to market them to club racers you’ll want to keep that in mind.
We purchase the plastic bits from our contract manufacturer.
^ That’s what I was thinking. Racing seats should be thought of as a safety feature. This article has some info that may interest you.
wow, $10K to get certified :o
Perhaps I will stick to street seats… or no seats at all.
I cannot imagine any problems with how I would make them, probably vacuum infused with some good epoxy resin. and plenty of thickness to the seat.
Making seats is not the same as making a random composite panel that has no engineering put into it and made in a questionable shop environment with little to no quality control over materials used. VERY different, and it carries huge safety implications.
There’s probably some insurance issues as well. Don’t want someone getting injured in your seat after an accident.
Yeah, the last thing I need is to get sued over some dumb seat.
I think you are thinking of something like this.As someone who spent much of my summer at track days I would even consider buying a seat that wasn’t FAI approved.
My track like the one below is way overbuilt but it’s safe.
I would like to build racing seats, but I sure do not want to spend several thousand dollars to get certified.
I know SNELL approval for helmets adds about $25 per helmet. The mfg’s actually pay SNELL for every single one of those stickers on the back of helmets. That may or may not include the destructive tests that SNELL does. See, I would pay $50 for each seat to be certified, BUT NOT thousands $$$ up front…screw that.
I used to work in at Saf-T-Cab in Cali… they destructive test their cabs by raising them 30 or 40 ft into the air via crane, then drop them. LOL… to certify the design and welding.
Yeah, the Tillet carbon seats are awesome looking. To be certified racing seats they have to have hard mounted brackets that do not adjust via slide or latch. You would have to unbolt the seat and move it forward or aft then bolt it back down. Makes good sense.
holy sh*t! what are you driving? a rocket propelled cement truck? :eek:
A rocket propelled beautiful truck… 
I am sure you copied the seat design from here…
No…it came from a NASCAR team. It may not be pretty but its safe.
