How low did you mount your race seat?

I've tacked together a mounting bracket to get the seat as low as I can, while still seeing over the dash. Before I finish up the welds, just wondering how low is too low? Might it affect heel-toeing etc?

What ever makes you feel comfortable .

what gives you the head room you need

which is why mine is bolted directly to the floor (CRX)

With me it was all dictated by leg position. With the seat on the floor, my legs were unnaturally straight and this made it difficult to work the pedals properly, sort of like when the seat is too far back. So I kept sticking pieces of 1x3 under it until I got the height/angle where I wanted it, then made steel brackets to match.

I mounted mine directly to the floor, after cutting the rear legs off the seat and removing the factory mounting points. But that's me, a guy with short legs and a long torso in a Miata. If I was setting the same seat up in the same car for my wife, it would be different. Set yours up for you.

Helmet clearance, leg room, vision over the dash/hood and driver comfort plus available room in car are all factors.

Mounted my race seat in my Saab a little too low. Ran with a phone book on the bottom of the seat so I could see over the hood. Ran one race without the phone book, and kinda liked how low it was. Threw the phone book in the trash after that.

Mounted mine too low, thought I had it right and ended up exactly where the stock seat was. At 5'6" I have to run without the shaker hood scoop to see the turns well. There was so much fabrication and modifications involved in the cage and full containment seat mounting there's no way it's getting changed. Gonna have to try larrys phone book trick.

Well, I couldn't fine a milk crate in anything other than the standard 12" height, so, uh, 12" off the floor for me.

Ok, seriously, I mounted it a bit lower than the factory height (about 1/2"), and with the fact that the seat is way thinner than a stock omni seat, I end up about 6" lower.

Whatever else, be sure that when sitting properly in the seat (as you would with harnesses on), that the top of your helmet is at least 2" below the top of the roll bar (the "halo bar").

This is the standard for almost all racing groups.

I would raise the front part of the seat relative to the back part, maybe about 2" or 3" or so. I'm talking about the actual "seat" part and not the backrest part. I don't think you'd want the seat parallel to the floor. This is the same point J-man was making above.

aeronca's right. I have a 10 degree layback Ultra Shield Spec Miata seat which is raised about 1 1/2" off the floor (measured at the rear) and is then tilted back a bit. That way my legs are slightly bent making pedal operation much more intuitive. Hint: If the seat will be adjustable, mount the tracks so that as the seat goes forward it also goes up. Much easier for a shorter driver to see out that way.

The roll bar main hoop is tall enough to clear my noggin. It's done on the 'straight line' open top car SCCA rule, that is a straight line from the nose of the car to the top of the roll hoop clears my head by 2".
