Seat suggestions

[Dbrank]

Hello everyone. I just ended up buying the car below. Primary use will be autocross. The only real issues are that im too tall for it. I need a bigger seat for starters. My head is near the top of the roll bar. My question is if I go with a seat such as a kirkey 38 series that have angled bases, would that drop my head down lower? Thanks.

also im not trying to spend a ton of money on it, The 38 series are about $170

I have a bunch of other plans for it so far but figured the seat should be the first thing to get sorted out.

I'd recommend ditching the seat entirely. Use aluminum sheet to complete the cockpit, and mold your own seat of two-part foam directly on top of it.

[Steve Demeter]

Two part foam is sort of OK. But it's energy absorption capabilities are essentially ZERO.

Bead seat or EPS insulation board cut and fit as Richard or Steve would do.

Yes it could be really dangerous if you Hit a cone lol

Kirkey, UltraShield or any other Aluminum seat will mount directly to the lowest point in the flooring. If you have cross tubes under your seat, then that is about it. You can tell your situation by what your current seat mounts on. The only other way to get your head lower is to increase the seat back angle and move your butt forward. Of course, that capability assumes you have the legroom or pedal placements to do it. I had an Ultrashield aluminum seat in my Legrand DSR. Moved it forward and tilted it backward to get the head clearance I needed to road race it.

Broomstick rule is generally used for helmet clearance. Run broom stick from top of rollbar to where it lays on forward most part of frame. Head should be under it for safety purposes. For SOLO, this is not generally checked unless your head is definitely above the rollbar.

Take the seat out. Sit as low as you can. Place your butt such that your helmeted head is as low as you need it and you fit in the car, etc. If everything works, then you use foam padding or make a backrest, etc to support your self.

How much do you see out of that mirror?

Those are SRF mirrors that I adapted for the Legrand. They worked great with a lot of placement and adjustability. They are larger than the usual Formula mirrors which increased the FOV.

Forget the broomstick deal. It doesn't appy for SCCA Solo. And many other clubs piggy back SCCA. And roll bar ht is checked in Solo.

From the SCCA Solo Rules:
APPENDIX C - SOLO® ROLL BAR STANDARDS
A. BASIC DESIGN CONSIDERATIONS
1. The basic purpose of the roll bar is to protect the driver in case the vehicle
rolls over. This purpose should not be forgotten.
2. The top of the roll bar shall not be below the top of the driver’s helmet
when the driver is in normal driving position, and shall not be more than 6
inches behind the driver. Exception: For Modified Category Specials (Sec-
tion 18.4), the bar must extend at least 2.0” (50.8 mm) above the driv-
er’s helmet in the normal seated position and a head restraint keeping
the driver’s head from going under or behind the roll bar is required. It is
strongly suggested that all roll bars extend at least 3.0” (76.2 mm) above
the driver’s helmet. In case of two-driver cars, both drivers must be with-
in the roll bar height requirement, however only one (1) driver must be
within 6.0” (152.4 mm) of the roll bar. In a closed car or an open car with
a removable OE hardtop which is equipped with a roll bar/cage, it must be
as close as possible to the interior top of the car.

There's more.

Looks like it will be a fun little ride, Bike motored? Does it have a body?

Interesting torsion bar setup

[Dbrank]

I’m not totally sure the history of the car but the previous owner said a guy from New York State built it. Torsion bar suspension with shocks obviously. Motor is a Honda shadow 1100 with a garret t25 turbo. Dual chains that go to a custom rx7 diff converted to chain drive. The car uses a lot of sprint car parts which is good so it’s rather widely available. I’ve been looking at the kirkey 21 series seats now. They have 40degree backs compared to the 38 series which is 20deg. I think that’ll move me forward enough to get my head lower. I have to cut the steering brace so my legs fit. I’ll raise that all up so I can fit. Then I’m going to add a rollbar around the steering wheel for peace of mind.

That car looks like a ****load of grins!
