1. The steering wheel sits too close to the dashboard.
2. The gas pedal sits much farther away than the brake pedal.
3. The pedals are offset to the right.
4. The steering wheel is offset to the right.

• I can't steer very quickly or precisely because either my arms are nearly straight, or I have the seatback pointing forwards. And that makes it almost impossible to drive with a helmet on, because the headrest is in the way.
• It's very difficult to reach the brake pedal: I can only put my foot on it while bending my ankle. A lot.
• My right leg is so close to the rim of the steering wheel that my right hand doesn't pass between the wheel and my leg when steering.
• I can't heel-and-toe without breaking my ankle.

Brake pedal
Most of the problems would go away if the brake pedal could be adjusted to sit a few centimeters deeper. Apparently, not many people bother with this kind of modification, as there wasn't much relevant information to be found on the Internet. Which is quite unusual, because the 964-community is very active, helpful and thoroughly knowledgable on a host of different subjects. There were some debates on whether or not you could adjust the height of the brake pedal. Some people claimed you could, others claimed you couldn't. I had a look for myself but didn't see an easy way of doing it. The OPC was very clear: you can't adjust the height of the brake pedal. As this was bothering me quite a bit, I asked a thoroughly knowledgable independent with 25 years experience racing Porsches (lots of those being 964RS's). Same answer: don't mess with the adjustment of the brake pedal.

Gas pedal
Having ruled out the easy solution of adjusting the brake pedal, it was time to consider other options. Both the OPC and the independent suggested bolting a little wooden block on the gas pedal to decrease the gap between brake and gas pedals. It's also possible to move the entire gas pedal by drilling new holes in the bottom of the car and fitting a longer rod to actuate the throttle mechanism. Another option is to buy a hellishly expensive aftermarket replacement adjustable gas pedal. I went for a wooden block :-) There's no hard and fast rule on how wide and how thick that block should be. It's highly personal, depending on such things as the width of your foot, the flexibility of your ankle, the particular heel-and-toe technique you employ, and your preference to have brake and gas pedals close together (with the risk of hitting the throttle when braking hard) or spaced apart (which makes heel-and-toeing using the side-flip technique more awkward).

I like to use the side-flip technique and am used to driving cars that have little space between gas and brake pedals, so I went for a relatively wide block. The block isn't very thick, as the width is more important to me, but it seems to do the trick. The actual dimensions are: 14.5cm x 7.5cm by 0.8cm thick. Of course, getting the dimensions right is a process of trial and error. I might go to a narrower and/or thicker block in the future.

Steering wheel
Solving the heel-and-toe problem by adding height to the gas pedal of course increased the severity of the steering wheel being too close to my right leg. There's two things that can be done:

1. fit a steering wheel with a smaller diameter
2. extend the steering column

Option number 2 was much more attractive. There are three ways to do this that I'm aware of:

• fit an original Porsche 964 steering wheel with an extended hub
• fit an aftermarket wheel and use spacers
• fit a Porsche 993RS wheel and add a custom-made hub

Using an aftermarket wheel (Momo has some nice steering wheels) was a serious option. However, I needed about 6cm of column extension, which is a bit much to reach elegantly with spacers. In addition, it's hard to find a 38cm diameter aftermarket wheel that looks good. Most are smaller.

You guessed it: I went for solution number three, an original 993RS wheel with three spokes. This wheel comes with a hub that can be extended by a competent metal-worker. The new 993-hub fits on the steering column (which solves the problem of getting the horn to work) and is extended by a made to measure one-piece spacer that's 6cm long. The 993-wheel is attached to the extension in such a way that it's off-center. The centerline of the steering wheel is about 1cm above the centerline of the steering column, giving 1cm more legroom when you are traveling straight ahead. Which is when you need it, because most of the braking is done with the front wheels pointing straight ahead. The cost of this solution is comparable to the cost of the original 964-wheel with the extended hub, but in this case you get a custom-made, tailored solution. The only downside is that I can't reach the control stalks on the steering column with my hands in a normal steering position. Fitting the wheel and fabricating the extension was done by Jos de Bock, who did a very good job.

Experiences so far
The big question is of course, "do I like the results?" Based on approximately 1000km driving with the new setup, including 6 laps on the Nürburgring, I can say that I love it. It is a huge improvement. I can now put my foot on the brake without fear of sliding off the pedal. I have lots of room to turn the wheel, so I don't have to move my hands around on the steering wheel when cornering. The 993RS-wheel has a thicker rim than the 964-wheels, which feels very comforable. Heel-and-toeing is pretty easy. I might replace the wooden block on the gas pedal with a slightly thicker one, but I'll do some more kilometers first.

All in all the steering position is much more relaxed and inspires much more confidence that if you have to steer quickly, you can do so.
