Race Seat & Harness Install

April 14, 2001

Since I am doing more and more driving events with the 914, and also because my original tan basketweave seats are pretty thrashed and the correct fabric is NLA, I decided to put some race seats in the car.  I wanted some lightweight, FIA approved seats with 5-point harness pass-thrus -- plus of course they had to be a suitable size for my body and for the 914. 

I went with the Corbeau Forza seat, which is a tube frame design weighing 16lbs each. They are affordable at around $220/ea, and fit the 914 quite well without conflicting with the center console or e-brake handle.  I do have the backpad out, and a Stable Energies harness bar installed: I am not sure how well this would work with the factory backpad in place.  For the harnesses, I went with the clip-in Schroth camlock setup, which is expensive but extremely high quality.

Unfortunately, the holes in the brackets were off by about 1/2", so I had to drill an additional hole in one end of each rail to get the necessary spacing. I actually did this on the "front" of the rails on one seat and the "back" on the other. Both required a little additional clearancing with a drill for the adjuster mechanism in the rails to clear the hardware, so it is kind of a toss up which end to drill.

You MUST use exactly the right sized hardware for everything to clear. I believe I used M8x20 bolts (possibly M8x16), with smooth washers and lock washers where appropriate, and M8 nyloc nuts.

The rails and adapter brackets assembled -- do this prior to mounting to the seat base. There is no room to tighten or adjust the brackets once bolted to the seat.

Clearance is tight, but it works fine.

I spent a little time doing some quickie cleanup of the floors -- cleaned out a bunch of nasty old dirt and crud with the shop vac, wire brushed and zinc-sprayed the areas showing surface rust, and then rattled-canned some Ravenna Green where needed.

Mounted the sub strap through the floor -- 1/2" hole, sealed with Wurth undercoat.

This shows how much room is left with the backpad removed -- the seat is in my normal comfortable position here (I am 5'10" but have relatively short legs...)

This is the hardware to 'properly' bolt in the shoulder harnesses. (I ran them in the first event or two with them wrapped around the guide bar, but that is not a good permanent installation.)

Comments and Suggestions:
Ethan Comments: Just a few questions. How tall are you, and do you fit with a helmet on in the car? Does the e-brake handle clear the seat when in use?
