For drivers who are tired of guessing
Too many ideas.
Not enough clarity.
We show you what actually moves lap time, so you do not waste limited track time testing the wrong thing first.
Need help interpreting this for your weekend? We offer guided interpretation and prep packages.
Track. Car. Verdict. Under 60 seconds. Works with just your track and car.
User stories
What changed once they stopped guessing.
Short, real outcomes from drivers who used a ranked verdict instead of chasing every idea at once.
How a track-day driver gained consistency
He stopped chasing power and focused on tire grip and braking zones. The lap delta shrank across every session.
Why so many changes did nothing
A small team rotated setups all weekend and got the same lap time. The verdict showed drag was irrelevant at that track.
When one change finally made sense
They reduced mass instead of tweaking aero balance, then used the verdict to target two corners and got a clean gain.
What you get
A verdict, not a dashboard.
Here is a real example. A Porsche 911 GT3 at Laguna Seca. The engine ranked every lever and told you where to focus.
Grip dominates this track. Do not touch drag — it is not where the time is.

Example output — Laguna Seca, Porsche 911 GT3This is what the engine returns. Ranked levers. A clear directive. No options to wade through.
What this is not
Clear about the edges.
This tool does one thing well. Knowing what it does not do matters just as much.
Not a setup tool
We rank what matters. We do not prescribe spring rates, ride heights, or wing angles. Execution stays with the engineer.
Not an optimization promise
No guaranteed lap time gains. The output informs prioritization — it does not replace testing or driving skill.
Not CFD or detailed aero
This is a fast lap-time simulator that compares relative impact. It does not replace wind tunnel work or surface-level CFD.
Not a replacement for experience
Engineering judgment still matters. This tells you where to look first — what you do with that is up to you.
How it works
Three inputs. One ranked verdict.
A physics simulation perturbs each vehicle parameter and measures what actually moves lap time. It runs on your track and car inputs, not your weekend data.
Select your track and car
Pick from the track library and choose a vehicle platform. The engine uses geometry and vehicle properties. Nothing from your weekend.
The engine ranks every lever
The simulation perturbs grip, downforce, mass, power, and drag independently. Each corner gets a sensitivity score. Results come back ranked by leverage.
You get a verdict, not options
Act on these. Monitor those. Ignore the rest. Corner-by-corner breakdown included. Save it as your pre-event brief.
