Original second owner 911 Carrera RS, now owned by the State of Art Collection and driven by Gijs van Lennep in last weekend’s Porsche Classic Challenge 2012.

In our last post about modifying your early 911 in a reversible way we covered suspension set up and tires. Today we cover shifting and interior mods.

If there is anything that annoys in a well cared for classic, then it must be a sloppy gearshift. The original shifter set up of both the 901 and 915 transmissions was quite solid and can be restored by addressing the right areas. However, whilst you’re at it, you might consider going all the way and changing just a bit more than the original [...]

We have some great news for owners of earlier 911s through the Carrera 3.2: We now have the Zuffenhaus RSR brakes in stock to bolt onto your original chassis! It allows you to take advantage of the supreme stopping power of these race proven brakes.

The original brakes on all these types of cars were single piston equipped. The real heavy duty, race oriented brakes were reserved for the Turbo 3.3, which came with larger, wider, cross drilled ventilated disks and for piston brakes in the configuration of the 917 and 911 RSR race cars. Contrary to popular belief 917 brakes look nothing like RSR brakes, as they were not equipped with cooling fins. Those were only added for the 2.8 RSR. The internals however were the same.

The reason you should get our RSR brakes is that it is the only big-brake bolt-on solution which fits both front and rear bolt spacing and [...]

In our next chapter of the Sports Mods we take the suspension to another level. Based on our experience a road going early 911 which has an occasional track day outing and runs in a navigation rally now and then needs no adjustment of the front torsion bars, nor sway bar size. The Green Meanie was such a car (see Part 1) and Silverado, despite its more radical S/T look, still runs standard suspension up front. To take your early 911 to the next level of reversible sportiness you swap out the rear torsion bars. We went with the early Turbo spec of 26mm and in combination with the rear sway bar you are now very near the optimum for these early, narrow body cars.

It is now time to consider ride height adjustment, since your rear suspension has been dismantled any way. A corner weighting job and ride height adjustment are the final stage [...]
