85L / RS Skid Plates are a go!

Well, we’ve just trial-fitted the first run of our skid plates for the plastic 85L tank, and they’re perfect: Finally you can pull that ridiculously cool, vintage RS tank (actually offered in 1970) down from the attic and put it back in service without fear of damage from road hazards. We designed these after the factory Rally skid plate used under the shallow-bottomed tanks, paying careful attention to the proper large radius at the front (for correct visual appearance when mounted), the overall width, and the placement and location of the mounting holes in the trunk floor – to produce …

931 project.

Every so often, we deviate from 911 buildwerk; at the moment we’re finalizing the sheet metal phase of a 931 project. In fact, here’s a shot from this morning’s panel gapping and alignment: The 924/44 series has less adjustment than the air cooled 911, but the character lines are important and the panels still need to flow into each other properly to maintain the shape-aesthetic that Porsche is known for. On the hot rod side of things (we are Zuffenhaus, after all) this 931 is getting a 951 intercooler – and is having the factory mounting grafted in: The Celette …

RS Lightweight-inspired Seat Mounts (with a 30mm drop!)

Well, we’ve just picked up the first four production sets of our RS Lightweight-inspired seat mounts. These were designed to lower vintage and reproduction racing bucket seats in the F model 911.   After being unable to make use of the height adjustment holes in vintage seat sliders to recline the seats during a two week cross-country trip due to the high positioning of the seat at the lowest setting, we sat down and designed our own mounts. We were inspired by the minimal architecture of the RS Lightweight mounts used in competition in the early 70s, and held that …

RSR Rally Muffler Reproduction

We needed some R/RSR and ST/RSR Rally mufflers for some project cars that are running SSIs/heat exchangers (require heat) and after pouring over period photos we decided to convert some Dansk SS mufflers to make what we need. We’ve done a small run of perforated inner, double walled stainless 70mm exhaust tips, blockoff caps, and created our own fixture to install them at the correct upward angle and spacing of the original part: Still researching the correct flat grey coating for these, so if you have any insight there, please let us know!

MSRSR update: RSR Trailing Arm Mounts

Entering the final bit of welding and fabrication (metal-wise) on the Mary Stuart project, and just finished up the RSR Trailing Arm Mount conversion work; here are some photos: These allow the use of 930 trailing arms – needed because of the widened track and offset of the massive wheel/tire combo that the Mary Stuart RSR used.  The 930 arm has significantly more robust wheel bearings than the Carrera arm to deal with the increased loads of a widened track. For this project, we wanted the mount conversion (which is actually a front pickup point relocation as the 930 arms …

Two Weeks in a 1972 911: Rennsport Reunion V (Part III)

PART III | Bring it home *author’s note: while launching the new site, I realized I’d never posted the third part of the RRV drive in the ’72 911! Please excuse the delay, here’s the rest of the journey: click here for PART I click here for PART II   Grand Canyon   Normally I’m a planner. I map out my trip in excel, keep a running tabulation of expenses, mileage, etc. Accordingly, I’d made all the appropriate reservations and budgeting before I left. However, on Sunday night it had occurred to me that I’d never been to the Grand …
