The Porsche 911 GT3 RS 
has seen wide approval since its debut. It’s 4.0-liter, flat-six engine produces 500 horsepower and 339 pound-feet of torque – a gain of 25 horsepower and 15 pound-feet over the standard GT3. To accommodate this extra power and to increase downforce, the RS has a huge rear wing and a front lip that surrounds the front fascia. These aerodynamic modifications, however, might be too much for the RS.
According to at least one GT3 RS owner, the downforce created by the RS’s aero package is more of a problem than anything. As shown in the video, the RS’s tires actually make contact with the wheel wells as the driver takes a spin around the Nurburgring. It is quite evident that the suspension just isn’t stiff enough to compensate for the amount of downforce. According to the owners blog post, his RS has a stock suspension system, so it looks like this problem may be a design flaw. The question is, how did this flaw get past the engineers while the RS was in the testing phase?

Why it matters
After a little bit of research, the problem doesn’t appear to be limited to the GT3 RS shown in the video. Some owners have even made modifications to the wheel wells in an attempt to solve the problem, but those modifications don’t make up for the travel in the suspension system at higher speeds. Did Porsche neglect to update the suspension system to compensate for the additional downforce over the standard GT3? It sure looks that way. So much for the RS being a track-ready supercar.
