I was in the market for an adjustable gas pedal for my 964 - and found one that works for all 911's (G-bodies included) up to the 996. l wanted to take care of the awkward pedal spacing in the pedal box. Anyone who has driven one of these cars, knows about the height difference between the gas pedal and the brake. It makes heel-and-toe downshifting difficult at best; impossible, depending on your ankle mobility. What drew me to Wings Air-Cooled Specialties 'The Third Foot' pedal is it is completely reversible - no need to drill into your gas pedal or modify the pedal box in any way. I purchased one from their site - about $250.00 all in, and it shipped quickly. I received the shipment, opened the box, and received a handwritten note from the owner as well. The little things go a long way.
Wings Air-Cooled Specialties has been around for some time - but I believe it went dormant. The product patents were purchased, and the 'Third Foot' pedal is now back in production, according to Nick (their proprietor). All I can say is, I am impressed. The installation was extremely easy, literally taking 5 minutes, and two tools. Basically, the 'Third Foot' pedal slides over the gas pedal, and camps around it using an arm. Remove the clamping arm, install on pedal, re-install clamping arm, tighten. Adjust height (top, and lower two Phillips bolts) to preference for heel-toe style. Installation could not be simpler, and the pedal feels solid - it's made of aluminum, and there is not 'slack' or dead zone once you adjust it to suit.
It's made heel-toe shifting a breeze, and I've experienced zero rev-hangs or issues with it since installation. I heavily recommend it if you're looking for an easy-to-install, mad-in-the-USA, reversible, adjustable gas pedal.
