Default Seats and seat mounting?

Hi all - my fabricator is getting ready to do some cage updates, including adding NASCAR bars to the driver's side of the existing cage. He's offered to do custom seat mounts as well, although it looks like Sparco makes a bolt-in solution for the 3rd gen Camaro (http://www.sparcousa.com/product/seat-base-600-series). I'm leaning towards the Sparco Rev or Grid II (http://www.sparcousa.com/catalog/veh...pe=competition) for the seat, but would love some input (and/or pics!) of how smarter people than me have their seats mounted. Dumb/newb questions:

- Bolt-in seat mount per above, or custom floor-mounted? I'm 5'9", so clearance shouldn't be too big of an issue.
- Anyone using or recommend sliders? Seems like it would make access and/or snugging the belts down a bit easier, but as I will likely be the only wingnut behind the wheel, I don't need adjustability, nor do I want a possible point of failure.
- What else am I forgetting?

I've read through the GCR on seats and it seems pretty straightforward - mount it securely and safely. The seat frame that came with the car was just mounted to factory sliders with flat stock to adapt to fit...can't imagine that would pass muster today.

Thanks in advance,

Jason

We've been using FIA Sparco seats for years using Sidemounts and no sliders.
They bolt to fabricated brackets at original stock seat mounts. I think easiest is to have the side mounts fastened to strong floor mounting, some tie into cage--we didn't have room---do what's comfortable to you.

Thanks Dean (and others that responded)! I appreciate the feedback and am going to have the fabricator burn in some heavy duty seat mounts to the floor and/or cage (if possible).

You mentioned the FIA cert (which I believe the Sparco I'm looking at has), but I've also been checking out other options from Kirkey and UltraShield that don't have that. For some reason I had it stuck in my head that the seat had to be FIA certified, but I may have been mistaken as I can't find that anywhere in the seats section for the GCR or the ASedan appendix. Am I just missing it, or are non-cert'd seats legal? Not looking to compromise on safety, but just want to make sure I check out all options.

Thanks!

Jason

FIA certification was never required. There was a requirement that, if you seat was an FIA certified seat, it had to be mounted according to the certification. This was a problem for some people who wanted sliders and none were certified for the seat. It got pretty complicated when seat back braces came into the discussion. All that went away this year when we just require:
9.3.40. SEATS
The driverís seat shall be a one-piece bucket-type seat and shall be securely mounted, so as to provide fore/aft and lateral support.


Mount it like your life depended on it. If they tech inspector reaches in and shakes the seat from side to side, or fore and aft, he probably won't pass it.

Thanks Jim! I had mentally made a note to reread the seat section of the GCR before ordering, and it looks like it got significantly more streamlined since I had last read it.

Agreed on safety - I'm putting more money into cage enhancements and safety versus "go faster" bits that I wouldn't be able to fully utilize anyway. The car will be fast enough for me for now, and in the mean time, my goals are make it safe, make it reliable, and stay out of the way of the faster drivers.

Thanks again...

Jason

By the way, the one piece reference is to the fact that it does not have a seat and a back, like a stock seat, not whether it is an aluminum seat made of several parts assembled together. But a seat that fits and is well made and mount it with better mounts than you think are necessary.
