The Porsche 993 variant of the iconic 911 is perhaps one of the most significant of all the 911 models. It was in many ways a game-changing model that incorporated many of the design features still found on 911’s to this day. It is also the last of the air-cooled Porsche models. The 993 is both the last of the legendary air-cooled 911s and a bridge to the newer technically advanced models. The 993 is also considered by many to be the best looking of all 911s. These things have made the 993 a desirable model for collectors and Porsche aficionados. Leave it to our friends at BBi Autosport to build the what we think is a mind-blowing, game-changing retro modern build of a road going 993 that combines and functionally integrates state of the art parts straight out of a modern GT race car.
We were lucky enough to get to look at the while it was under construction and will do a full write-up and feature on it when it is completed.
BBi started with a 993 C2. The shell of the car was stripped to the bare unibody and media blasted. At this point, BBi seam welded the unibody and built a streetable but inclusive cage to provide a better level of protection to the driver and to stiffen the chassis to close to modern 911 levels. The cage was designed to be as unobtrusive as possible but still, give rollover protection. The unibody and body panels were then painted a flawless silver.
The hood and decklid are carbon fiber and the rear decklid has a duckbill spoiler to give homage to the older RS models of the 911. Here the huge wheels and tires are being dummied up to see how the RWB body kit will fit and if the wheel and tire fitment will clear everything.
The BBi Autosport 993 has been partially assembled to have one of the famous Japanese RWB or Rauh-Welt Begriff aero kits installed. There is an air of exclusivity to have one of these kits, each RWB kit is handmade by Nakai-San with a waiting list of over a year. When your kit is ready, Nakai-San personally flies over to a prior agreed upon place to install the kit with an entourage and a lot of fanfare. The car has to be ready to Nakai San’s requirements for him to work on it. The body and paint must be complete, the aero kit must be painted to his spec. The suspension, other bodywork, wheels, and tires must be on the car and ready. The whole thing plus entourage seems like a lot of hype for us but its all part of the RWB experience if you are into that sort of thing.
The 993 911 was the first 911 to use a multi-link rear suspension and an alloy rear subframe to hold the engine and suspension as a unit. The multilink suspension was designed to provide better camber control for more grip and to provide dynamic toe in. Both of these features were used to get away from the traditional 911 semi-trailing arm rear suspension with its strong tendency to give trailing throttle oversteer. The new rear suspension was a revolutionary change that vastly improved how the 911 handled. Having the engine and suspension on a separately isolated subframe allowed Porsche to use stiffer suspension bushing and motor mounts without increasing NVH.
