Hello all,
We're building a SM and wondering what the most common seat choice is for a guy 6'3"? Also, do most cars run a passengers seat or not?
Thanks,
Paul

not sure about the right seat for a 6'3" driver, not real common to run a passenger seat. I have a race seat and harness I can pop in for instructing or giving "rides" but leave it out to race

The Ultrashield is a good choice. I use the stock seat rails, removed the stock front hump and rear mounts, welded in some 2" x 2" plates and bolted it to the floor. I originally only removed the rear mounts, but the additional layback made it uncomfortable with the hans and my shoulders were to far away from the wheel. The key is to use a small diameter steering wheel to have enough room for your knees. And make sure your cage harness bar extends back past the seatbelt towers so you can move the seat all the way back.

I too am 6'3" one of the most important factors will be your shoulder height in relation to the holes for the shoulder harness belts to pass through. In my case I am taller in the torso than most people and have to have the harness holes moved up in order to accomodate my body type. Most seat manufacturers have the seat dimensions on their website so you can find one that best suits your body.

I am 6'3", 230lbs and use an Ultrashield 17" seat. I might be able to use a 16" because the 17" leaves a little extra wiggle room, but I was worried the 16" would be too snug and I wasn't in a position to test sit before I bought. I also run the same kind of seat in my passenger side for DE's, instructors, ride alongs, etc. Ultrashield makes a good cost effective seat for miatas and it is relatively easy to install.

You'll probably need to mount the seat directly to the floor (using spacers to get the layback angle right) based on your height. I cut/ground the rear mounting humps out and bolted the seat to the floor with 4" plates on the bottom of the car. Leave the front cross member intact (where the front of the OEM seat tracks mounted). You'll also need to "massage" the transmission tunnel with a small sledge hammer where the right/front corner of the seat contacts the tunnel.

I'd suggest finding some local people or a shop and sit in as many seats as possible. I did that when I switched from a Kirkey to a Recaro and I was amazed at the differences between all of them.

There's some good threads on mounting seats, right hand side nets, alum vs FIA, etc.

Also, given your height, look into a steering wheel spacer to help the wheel clear your knees. I'm 6'2" with longish legs and the spacer helps quite a bit. At 165 lbs I used to use a 15" seat and it was perfect.

Good luck, and welcome to the addiction.

I'm 6'3" as well... I originally used an Ultrashield bolted to the floor, tilted back. That worked out well. +1 on a smaller diameter steering wheel with a spacer for the knee clearance.

I recently upgraded to a RaceTech RT4009HR, mounted with Racetech mounts, tilted back, with no bottom cushion. It's a really nice seat and I have a decent amount of head clearance...

Last year I had the Kirkey pulled out and put in a Sparco halo seat. Let the pros do it as when the big one comes I wanted it to stay intact. Had mounts made for the Kirkey on the pass side for instruction. I use a larger, flat bottom steering wheel for knee clearance. No spacer. The larger wheel gives you a bit more leverage and therefore doesn't have to be as close. Remember, the better fiberglass seats weigh lots more than an aluminum seat so start looking for weight savings now.

[Edit] oh, you have a '99.....Nevermind.

Thank you for all of your suggestions!!!!

We will be visiting Rush Motorsports in the near future to get his input too. Your helpful comments and suggestions have brought us a long way up the learning curve.

so this means the sparco halo will not fit a '99?
i am asking because i just picked up a nice 99 and am a big fan of using a halo seat.

No, I think muda was referring to looking for weight savings. Making weight in a 1.6 can be done, but a fiberglass seat weighs more than an aluminum one.

Not as hard to make weight in a '99, so the added seat weight isn't as big of a problem.

Yes, the theoretical attempt at equality made by dropping the 1.6 weight to 2,285 lbs. makes it very difficult for those over 200 lbs. to make weight and equip a car with the highest level of safety equipment. A top cage, fire system, fiberglass halo seat, etc. all weigh significantly more than the cheaper alternatives. Add a Torsen and a cool suit to that and it's damn tough to get even close. I weigh in at 210 lbs. dressed and I'm 35 lbs over with a couple of gallons of gas.

So, this winter I'm going to have a NASCAR bar installed on the pass side so I can gut the door and I'm on a serious weight saving program.

Unfortunately the weight of the additional NASCAR bars negates the weight saved by gutting the inner door sheet metal. Ain't I just a ray of sunshine.

Really? I would be removing a large X bar and replacing it with the NASCAR bars. Then removing the glass, electric motor, channels, door panel, etc. I thought it was a net 15 pound savings? Chris Windsor does not lie. [yep]

Thanks, Mike. Nice to hear that after stealing and eating all the kids' Halloween candy. ==burp==
