Tiff Needell and Vicki Butler Henderson of Fifth Gear have taken two of the most extreme BMWs and Porsches out on the track for a head-on-head comparison – it’s the BMW M3 GTS meets the Porsche 911 GT3 RS. If you’re not already watching the video after the jump, then we’re not sure what you’re doing in life.
