Nigel Greensall Qualifying an SR3 at Rockingham
Pro driver and Coach, Nigel Greensall, qualifying for the Competition Car Insurance Radical UK Cup in March 2010 in an SR3. Nigel Greensall – “You spend more time in slow corners than in fast corners, so you can often gain most lap-time by concentrating on these areas. “Exit speed is important, but equally as important is minimising the time spent in the corner. You often see drivers taking a big wide entry into hairpins to gain a fast exit speed, but due to the slow speeds involved, this sacrifices huge amounts of lap-time, in order to gain a few tenths down the straight.’ The hairpin at Rockingham is a great example. Take the two lines taken in the same car at the same race meeting in the above image. The blue line was taken by my team-mate taking a wide entry, and the red line is my preferred approach, which is braking at a diagonal towards the first apex. The red line is 14m shorter than the blue line, meaning I spend 0.45s less time in the corner. The blue line does gain 2mph down the straight, but this is only worth 0.15s. Therefore the gain from the shorter line is 0.3s.” Watch the YouTube footage and you can see the difference in lines as the SR8 in front of me takes the wider line.
