I’d chase this from the front — raise the front spring gap…

The problem?You don’t keep track of anything.

Well — maybe you do. But not properly.

Ten runs a day, three changes a run, none of it written down. Pace comes and goes and nobody knows why.

“I went faster.”

did you?

“Tyres seem gone.”

are they?

“The spring change seemed better.”

was it?

Easy enough that you’ll actually use it.

Between runs there’s a battery to change, tyres to check and someone talking at you. Notes lose, every time. So the day ends with a fast run you can’t explain and a slow one you can’t rule out.

  1. 01Pick the car and the event — both remembered from last time
  2. 02Tyres and conditions, two taps
  3. 03Lap times attach themselves when timing posts
  4. 04Say what the car did, in the words you’d use on the rostrum

Ask it anything.

It already has your runs, changes and lap times — so ask the way you’d ask the guru at the track.

Car feels loose on exit of the long left, but only after the first four laps

I’d chase this from the front, not by freeing the rear more…

Ask the Engineer…

Understand the real picture, stop guessing.

Every setup change is marked on the timeline next to what it did to your pace. No more “I think that helped.”
