AVB RaceLabs: karting race engineering
Your pit wall.
In your
pocket.
Tyre pressures, gearing, ballast and grip, worked out for your kart, your track and today’s conditions with real maths and physics, not guesswork. And when you want to know why, your AI Race Engineer is on the radio.

A kart’s lap time is decided before you turn a wheel. Dozens of variables pull against each other: tyre pressures and temperatures, gear ratio, total weight and where the ballast sits, chassis setup, the shape of the track and the weather changing through the day. Get one slightly wrong and you lose tenths every lap, wear out tyres early, or blame yourself for a kart that was never right.
AVB RaceLabs works all of it out. It combines your kart, class and weight with the track’s real geometry (every corner, straight and braking zone) and the weather for your session: air and track temperature, grip, wind and rain. Then it runs the engineering maths and physics: how hot your tyres will get, how much grip you’ll have, which sprocket suits the straights and corners, how much ballast and where.
The result is a kart optimised for this track, on this day, before you go out. So when the flag drops, the difference is you. And your AI Race Engineer explains every call, so you learn why, not just what.

Running a team?
Team plans,
priced by drivers.
Parents, mechanics and coaches are always free. Drivers on a banded team can take Premium for £9.
See team plans06 / Pit-wall Q&A
Straight questions,
straight answers.
Can I cancel any time?
Yes. Every plan, team bands included, is monthly with no fixed term. Move down from a paid plan and you keep what you paid for until the end of that month.
Can team members pay the team manager through the app?
Not inside the app: AVB never handles team money and takes no cut. The manager raises charges and invoices in the app, and each member sees what they owe and the team's payment details there. You pay the team directly, for example by bank transfer, and the manager marks it as paid, so both sides can see the balance.
What happens to my data if I move down a plan?
Nothing is deleted. Sessions, setups and Pit Kit journals stay. On Free, journal limits only hold back new entries; you can still open and edit everything.
Do parents, mechanics or coaches have to pay?
No. On a team they are free and unlimited. Team bands count drivers only.
What does the team manager get?
The team workspace (roster, approvals, assets, calendar and entries, workshop, driver invoicing) plus Premium-level analytics while the team has a band. The AI Race Engineer isn't included; it's Pro with AI.
