Champion Motorsports builds a 911 RSR version for the street that is lightweight with 575 horsepower - $400,000+ price tag
We are not too sure why Champion calls this a street legal version of the 911 RSR race car as that vehicle is based on the GT3. Champion started with a 997 Turbo S on the car you see here which means rather than a high revving GT1 race car derived motor it has the new turbo flat-6. This vehicle also had a PDK transmission which the RSR does not. The all wheel drive is also another difference versus the race car rear wheel drive. It would probably be more accurate to state this attempts to mimic RSR performance for the street as the name really makes no sense with all the differences.
Regardless, the car itself is quite simply badass. The body is stripped down and replaced with carbon fiber panels. The VTG (variable turbine geometry) turbos get upgraded. The exhaust is basically straight piped. The suspension gets 4-way adjustable Ohlins coilovers and new suspension arms. Super lightweight magnesium wheels round out the $399,000 package.
We wish we had the weight specs for the car but this is not something most people are going to be looking into purchasing anyway. A very cool build but not price effective or really reflective of the 997 GT3 RSR. We are honestly amazed no other site pointed this out.
