We spent the 2023 season in the Porsche Sprint Challenge paddock: coaching drivers at the track and on the simulator between events, and reading the telemetry between runs. We take what the data teaches in the simulator to the real circuit, and back again.
Track work and simulator work are the same job done twice: the simulator is where the lap is cheap, the circuit is where it counts.
Two years with the Lions Racing Team, TU Braunschweig. Responsible for the spring and damper system, and lap time simulation in Matlab: what a change to the car is worth before it is built.
A bachelor's in automotive engineering at FH Südwestfalen, and a master's programme in automotive engineering at TU Braunschweig. Vehicle dynamics, suspension and tyres are where the setup advice on this page comes from.
The same idea runs through the tools here: lift and coast, push-to-pass and the stint calculation all simulate the lap from your own data before you drive it. It also runs our game Pitwall Racing Manager: your first setup changes and what they do to the lap, learned by playing.
Improveyourlaptime is run by Fabian Rüth, founder since 2021: engineer, coach and sim racer. Every tool started as something missing on his own race weekend.
Test days are expensive and a race weekend gives you only a few sessions. We run your preparation as a programme: on the simulator before the event, with your logger data during it, and back in the simulator afterwards.
We read your logger export from the last event and put it next to your simulator laps on the same track. MoTeC or any other logger, we work with all of them. We compare brake points, minimum speeds and lines corner by corner, and agree with you which corners to work on before the weekend.
We map your setup onto the closest car the simulator offers and check that it responds to changes in the same direction as yours. On that baseline we try the changes you are considering, and take the promising ones to the track.
During the event we compare each run with the plan: brake points, balance and lap time. You get a debrief after every session, at the circuit or remotely on the same day.
What the track showed goes into the next preparation: driving notes, setup direction and corrections to the simulator car. With every event the simulator car gets closer to the one you race.
Write to us and we answer by e-mail, usually within a day. For a coaching session tell us the sim, the track and what you are chasing, and we come back with times that fit.
Record it, and the corners that cost you time are waiting for you when you take the headset off.
