Straight answers.

Drivers: early access is open, and PaddockPro opens to a first group of drivers soon. Garages: PaddockPro Workshop is available now, with a 14-day free trial. Anyone: the circuit visualiser and the knowledge hub are free to use now.

No download needed. PaddockPro runs in your phone's browser, on any phone: open it and add it to your home screen, and it works like an app. No app store.

Rookie opens first, to a first group of drivers from the early-access list, with Clubman and Pro following close behind. Join the list and we will tell you the moment your place is ready.

Forum advice is anecdotal: “this worked for my E36 on this tyre.” PaddockPro builds the spec around your car, your hardware and your goals, and gives you the reasoning behind it.

No. Whether you want grip on track or something livable on the road, you tell us the balance and the spec is built for it.

That is what Refactor is for. Tell it the limits of your hardware, for example a maximum of −2.1° camber, and it works out the best compromise around them. Refactor is in PaddockPro Workshop today, and comes to drivers at launch.

Rookie: your car in the garage with checklists and setup history, every circuit in 3D, and the paddock community: profiles, the activity feed, groups and badges. Clubman adds one alignment spec a month, with the reasoning, plus session logging, maintenance tracking and messages. Pro adds four specs a month, a second car, a setup library, and corner weights, tyre pyrometer and damper setup. See it tier by tier.

People with more than 20 years of motorsport alignment work behind them at TTR Motorsport: race teams, customer cars, track day builds. That reasoning, written down so you can use it. More about us.

Yes, unless you do it yourself. PaddockPro gives you the numbers and the reasoning; any garage with an alignment rig can set the car to them.

In minutes. Enter the car, the modifications and what you want from it, and the spec, with its reasoning, comes back in the same session.

If it has adjustable alignment, it is covered: road cars, track builds and race cars.

5,600+ circuits are mapped from real GPS data. Where a circuit is measured in detail, its corners and elevation feed into the spec. Try four of them in the visualiser.

At launch, each tier including everything in the one before it:

• Rookie (Free): Your car in the garage, with checklists and setup history; Every circuit, in 3D; Profiles, the activity feed, groups and badges.

Prices and the full feature list are confirmed at launch. Everything in each tier.

A full setup at TTR Motorsport is £350+, and most of that is the experience and reasoning behind the numbers. PaddockPro gives you that reasoning for your own car, from free on Rookie or £7.99 a month on Clubman, with a 30-day free trial. Set the car up yourself, or walk into any garage with your spec in hand.

£150 a month with no VAT to add, including 10 alignment specs, and £10 for each extra spec. 14-day free trial, no contract. See PaddockPro Workshop.

Yes. Clubman and Pro come with a 30-day free trial at launch, long enough to cover a track day, and Rookie is free. PaddockPro Workshop has a 14-day free trial.

The first 50 Clubman places are founding places: half price, £3.99 a month, locked for life. Places go in the order people join the early-access list.

PaddockPro Workshop has no contract: cancel whenever you like. The driver tiers' terms are confirmed at launch.
