New RSR Rotor Hats: ’73 RSR

Just finished first pair of rear rotor hats for 1973 RSR Steel Trailing arms. Should be just the thing for the recent FIA changes disallowing 930 arms for RSR competition in Europe 😉

993 Fuchs

We’ve been test fitting the Zuffenhaus Products 3-piece Fuchs-style Wheels on 993s today: This is an 8.0 inch fitment on the front of a 993 C2 with stock brakes and uprights. And the rear – These are fairly aggressive fitments – emphasizing the shape of the 993 body and fenders (hopefully in a way the factory failed to do!) The black 993 pictured is lowered significantly and has more negative camber than a stock example – it is what we consider a street/track set up, careful on speed bumps and driveways, but useable for daily commuting. Contrast that with a …

911RS Backdate Steering Wheel

Pictured above is the business end of THE SOLUTION for mounting the historic 380mm RS/RSR Steering Wheel (or the vintage 400mm for that matter) on the ’74-’89 911 steering column. Zuffenhaus Products has developed this 2-piece Hub assembly as part of our product catalogue specifically for backdate applications – now it is no longer necessary to become part of the legion of prototipo & accordian-style hub users when backdating your SC or Carrera! We’ll be adding this product to our webstore shortly, but thought you’d appreciate some photographs of the wheel/hub combo in the meantime: The pictures above show the …

H/H RSR.

Pictured above is a 911 that has quite a history with Zuffenhaus. It was, in fact, the first project to be taken on by the formalized racing & fabrication branch of our company. Through the years circumstance has brought Zuffenhaus and the H/H RSR together repeatedly. Our first involvement with this 911 occurred in 2005, preparing it to compete in the Targa Newfoundland with the fabrication of a full cage and associated safety equipment. It was a modest, blue 1981 SC at the time. The 911 returned from Newfoundland a crumpled mess – having rolled several times at high speed …

IN WITH THE NEW. 2012 Zuffenhaus Fuchs (-style 3-piece 17 inch wheels)

We are pleased to announce the all-new Zuffenhaus Fuchs-style wheel. Completely redesigned for 2012, this Version II wheel borrows no components from the original, but shares it’s DNA, as you can see for yourself in the image above. Like the game-changing first generation ZUF wheel, the Version II (shown on left in raw 6061T6 aluminum) bases its aesthetic mission on a properly-scaled, proportionally pleasant true 17inch center. Blind-fastened from the rear, proprietary “soft-lip” still in place, the new Zuffenhaus wheel continues the correct interpretation of the historical Fuchs sized for today’s tire options. Manufactured for Zuffenhaus by FIKSE, this new …

RSR fiberglass

No, not the challenging aftermarket bumpers/tail – the engine compartment ‘glass inspired by the historic Porsche race engines. Here are some pictures of what I’m referring to, taken from engine bay of a fellow rGruppe member’s ’72. Being the barely-amateur iPhone photographer that I am, I can’t possibly capture the light, texture, and tone of raw engine compartment fiberglass. Coupled with patinated aluminum and magnesium and yellow cad plated fasteners it creates a stunning, vintage aesthetic worthy of cooling fan whine and gutteral sport muffler sounds.

Intermission (Treffen)

964 AS BACK DATE PLATFORM Our visit to SVD got us thinking about the Zuffenhaus 964-based RSR that is now in assembly stage, as shown here: (please excuse the shop rag – the dust bunnies of our industry) The 964 is the ultimate back date platform – body panels and lines that do not stray far from the original pen but mechanical system developments that provide for chassis rigidity, functional climate controls, antilock brakes, and effective drivetrain right out of the box. SVD puts their signature on the 964 chassis as is well documented in the press – a synthesis …

MS RSR Body, Zuffenhaus.

Work continues on the Mary Stuart project @ Zuffenhaus. Technology is useful, but at the end of the day the hand (and eye) must be involved. This is the final handwork – contouring the quarter panel positive plugs, checking the shape where they will interface with the metal body, and correcting digital attempts to replicate flowing shape. Shortly, these plugs will be used to create molds to form the composite body panels.
