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!


Calipers Available!

  We’ve ended up with some additional un allocated sets of calipers for 930 (or 911 hot rods using 930 trailing arms!) Rigorously tested and vigorously raced in Europe for several years, our 2.8RSR Calipers are now available stateside. These are available RIGHT NOW, if you want a set without the traditional made-to-order manufacturing run time.   Email us with your full contact info a shipping address to get a personalized quote for immediate delivery for your project!


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 …

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!

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 …

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

. Two Weeks in a 1972 911: Rennsport Reunion V PART II | Rennsport Treffen Tehachapi Tuesday morning Chris and I got on the road at 6:30 – we had a track event at Buttonwillow Raceway  ( ) the following morning (already?!), and both of us wanted to be able to get to California early enough to relax and get a good night’s sleep. Heading west, the scenery was consistently and continuously impressive, one gorgeous vantage after another. The rest of the group at the La Posada – which had grown by 3 additional late model Porsches overnight – …
