Based a stone's throw from the Nurburgring, RSRNurburg is a one-stop shop for car rental and tuition on the Nordschleife. RSR also offers a premium trackday and Driving Academy experience at Spa-Francorchamps, where there are fewer corners to learn and the instructors can focus more on improving technique, without having to worry about Touristenfahrten traffic.
Suffice to say, RSR is very thorough with its approach, starting with the basics of car-handling and how to hold the steering wheel before moving on to the theory of how to actually go faster on the track.
The first thing I was asked to do was adjust the seating position to where I thought it should be - and it was completely wrong. My instructor, Luis Ramirez, explained that I sit too far away from the controls to maximise braking force - and, sure enough, moving further forwards made a massive difference.
