How to get the most out of it.

Slipstream is a co-driver, not a slot machine. It converges fastest when you give it clean, honest laps — here's the craft.

What it actually is

A tuning co-driver that solves your car's real balance from live telemetry — sixty times a second — and turns what it finds into one short list of changes at a time. It learns your exact car first, scores every run against your last, and steps its suggestions bold, then fine until the car stops improving. Then it tells you to stop.

Best practices

1. Learn the car first. One clean lap in Learn-Car mode does two things at once: it learns your exact car and hands you your first read off that calibrated baseline. A read against a learned car is worth three against a stranger.
2. Use Rivals for sessions. No traffic, same track, repeatable conditions — the cleanest signal you can feed it.
3. Drive like you mean it on read laps. It can't see grip you don't use, so push hard and let the car actually misbehave — a slightly ragged honest lap reads better than a tidy, careful one (drive too clean and it'll think the car's already perfect). Don't slide it around on purpose, though; just drive hard at your best.
4. One change set, one lap. Apply what it says, run again, score it. Resist stacking your own tweaks on top mid-loop — that's noise.
5. Commit honestly. The "I typed these in-game" button is how scoring stays true. If you only typed half the changes, the next verdict means nothing.
6. Flag what you feel. The issue chips get folded into the next fix. You're a sensor too.
7. Trust the hold. When it says "leave it — that's the window," it has landed the car in a strong, balanced spot. You can always keep fiddling, but past that window you're usually just trading one problem for another — so it's a good place to stop and go drive.
8. When it says tires, it's tires. After three runs of no improvement with grip levers spent, the limit is rubber, not numbers. Change compound, not camber.

Driving styles, honestly handled

Smooth targets a planted, predictable rear. Balanced leaves a hair of rotation. Aggressive deliberately keeps the car loose — and this is where Slipstream is smartest: it recognizes intentional snap rotation, lift-off and trail-braking as driver technique, not faults. It will only flag them if they're snapping uncontrollably or costing you exit speed.

As a rough guide, the styles pair to where you are as a driver: Smooth is the easy, forgiving starting point; Balanced is the all-rounder that suits almost everyone, leaning a little toward newer drivers; and Aggressive is where stronger drivers will want to live — it's the most competitive setting, and it'll find you the most pace even if you're not a pro yet.

What it's working on

• Gearing advice. The Coach currently leaves final drive and individual ratios alone — gearing recommendations are on the bench.
• Dirt & rally surfaces. The grip model is road-calibrated today; loose-surface characterization is in progress.
• Voice notes. Say what you feel mid-session ("loose on the brakes into 4") and have it synced to the telemetry at that exact moment — fully local, on the bench for a future update.
• Shareable tune cards. Send a friend the tune and the reasoning behind it.
