Default aftermarket seat mounting thread

I would like some input from the motorsports people about mounting competition seats in a WRX. Here's mine.

What I have:
Cobra Suzuka racing seat
Cobra side mounts, slider/bracket kit (sliders and subframe)
all from SubeSports (treated me very well)

Good: Cobra slider bracket comes assembled and bolts right in. It is heavy duty. It feels heavy. The Suzuka has a hole for a 5 point harness, or whatever else you can think of.

Small probs: Bracket has three holes front and rear for height adjustment...but you can't lower the front because the right front mounting bolt is in the way. Even with the seat lowered down into the side mounts it sits very high. I almost can't get in or out because the Suzuka has VERY high thigh bolsters.

Right now the side mounts are mounted inside-out because the seat is much narrower than the bracket. The side mounts still point inwards a little bit. The slider pawls don't disengage when the side mounts point in.

I reused the stock seatbelt latch. It bolts to a very sturdy threaded chunk of steel. I had to straighten the seatbelt latch piece in a vice. Otherwise it interfered with the center console.

The B-post rubs the shoulder, but I'm short enough where it sits just in front of the B-post.

All hardware was included EXCEPT the nuts and bolts needed to bolt the side mounts to the sliders. M8 hardware is used, but I don't like hunting for hard-to-find high strength metric bolts. Those 4 bolts should be included for the hundreds of dollars that I spent.

Fit: I knew it was going to be snug, but DAMN! This thing is a child's seat. I'm 5'6" 150 lbs-ish. I wear 31" waist Levis. I might have to make it my passenger's seat. If she can't fit, then she don't get a ride.

EDIT: Tip. Mount the side mount brackets all the way back on the slider. That way the lever for the slider won't hit when you pull up on it.

Going back and looking at Sparco side mounts and brackets, I can see some details. The side mounts have ovalized holes where they mount to the sliders instead of round holes. The Sparco sliders also have a bar in front instead of a lever on one side. Sparco hardware looks a little bit better than the Cobra stuff. The Cobra subframe is pretty dang good, though.

Yes, I find that to be a great comfort.

What's your seat setup?

Wedge brackets with Recaro sliders mounted to them, with Recaro side mounts mounted to the sliders and Pole Positions mounted to the side mounts. As far as I can remember, the side mounts are slotted a little bit on the front holes so that there is some room to play around with the mounting angles and such.

I'm tall (6'1"-2") but I'm mostly legs so I usually have absolutely no problem with being up too high in cars. For example, I fit in my S2000 with helmet on with about 1.5" to spare with the roof up. BTW, if you want to learn how to really drive that is the car to have. People who complain about the oversteer just don't have fast enough hands.

Talking I am a steering wheel Ninja master

My hands are plenty fast already thanks to a Mk2 MR2 with a rear weight bias, slow 4:1 steering ratio, and tendancy to toe out the rear wheels under hard braking (dive). I also graduated from the Dodge Omni GLH turbo school of torque steer. The WRX is a yawner by comparision.

Thanks for the Recaro info. Do the Recaro sliders have a lever on one side or a bar in the front?

Sorry... bar in the front.

Nothing's more irritating than slow steering eh?

I kinda like both types of steering. The MR2 had really slow steering, but it was really precise. You can fine tune your line in a corner and feedback is better. Quick steering just lets you make broad brush strokes. It can also save your butt if you mess up.

The Recaro sliders sound about the same as the Sparco ones. I really like the look of the Bride slider kits. http://www.tees-usa.com/seatrail.html

The FO-type ones for the WRX seem to combine the sliders with the subframe. The FG-type (not available for WRX) gets rid of most of the side mount plates too. Compared to the typical way seats are mounted, it looks a lot lighter. Not that you or I would care.
