How to get the most out of it.

Slipstream is your co-driver. Give it clean, honest laps and it gets to a good tune fast. This guide shows you how.

What it actually is

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

Best practices

1. Learn the car first. One clean lap in Learn-Car mode learns your exact car and hands you your first read off that calibrated baseline. A read against a learned car beats three against a stranger.
2. Use Rivals for sessions. Same track, no traffic, same conditions every lap. It's 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 misbehave a little. A 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. Don't stack your own tweaks on top mid-loop. That's just 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," the car's in a strong, balanced spot. You can keep fiddling, but past that window you're usually trading one problem for another. Good place to stop and go drive.
8. When it says tires, it's tires. After three runs with no gain and the grip levers spent, the limit is the rubber. Swap the compound. More camber won't get it back.

Driving styles, honestly handled

Smooth targets a planted, predictable rear. Balanced leaves a hair of rotation. Aggressive keeps the car loose on purpose. This is where Slipstream is smartest. It treats intentional snap rotation, lift-off and trail-braking as technique. It won't flag them as faults. It only steps in if they snap uncontrollably or cost you exit speed.

Roughly, the styles map to where you are as a driver. Smooth is the easy, forgiving starting point. Balanced suits almost everyone, leaning a little toward newer drivers. 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 work 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.
