Car Setup

A car's mechanical configuration lives in two places inside its detail view. The Build sheet button in the car hero opens a side panel with the car's details and its build sheet specs; the Setup view of the car's Build tab is a setup workspace -- alignment and corner weights, springs, dampers, aero, the tires fitted, the sessions run, and the history of what you changed between them.

A setup is a named configuration -- "Dry -- VIR Full", "Wet", a qualifying sheet. Each setup keeps a version history: every time you re-measure the car or change something on it, you add a version, and the sheet shows what moved since the last one. Save as many setups per car as you like; one at a time is fitted to the car (marked Current), and the rest are alternatives you can switch to whenever.

On an upcoming or active Track Day with this car assigned, a Setup card in the day rail shows the sheet linked to that day, or Currently fitted on the car. Open car setup lands on this tab. Past days hide that live card -- completed sessions keep the measurements they saved at the time, even if you edit the sheet later.

Build sheet

The build sheet opens in a side panel from the Build sheet button in the car hero, over whichever tab you are on. (The Parts view of the Build tab is a separate table of the parts fitted to the car, where a part comes off the car.) It reads as a set of tables, one per system, and each row says where its value comes from:

Every row has a Detail (the label), a Spec (the value), and a Source column. Rows marked this sheet are columns on the car, edited here in the sheet whether you typed them, scanned them from the window sticker, or let Research Director fill them. Rows from the setup sheet, pads, tires, and car details are read from those records and update themselves -- change them at the source. Parts rows are the parts you have switched onto the sheet (see below). Empty cards are skipped; when nothing is filled in at all, the panel offers the window-sticker scan, Research Director, and Edit in one place.

The eye at the end of a row hides it from this view without deleting it -- the row folds into a N hidden rows line at the foot of its card. Open that line to see the hidden rows dimmed, and the same eye brings one back. Hidden rows are about your view: what the public page shows is chosen in the Profile & sharing drawer, and a band at the top of the sheet says whether the car is private or link-shared.

Editing the build sheet

Click Edit in the panel header to edit the sheet in place. Each system becomes a group of fields with the same eye beside each one. Rows that come from another record are shown greyed out with from setup sheet (or pads, tires, car details) so you can see they are on the sheet, and edited where they live. Empty fields are left off the sheet. Save build sheet writes everything at once; Cancel discards the draft.

• Add part on a system's group opens the add-part form preset to that system. A part saved from here goes into your parts inventory and lands on the sheet.
• From parts lists every part logged for the car with a switch. Switching one on puts it under its system on the sheet and features it as a modification on the public page -- the two are one list. Switches are part of the draft: they apply with Save build sheet and Cancel drops them. New part adds one without a preset.
• Extras holds free-form rows -- a Detail label and a Spec value, like "Cold-air intake" or "Short shifter". Each row shows which card it will file under as you type its label.

Auto-fill from web

When nothing is filled in yet, the panel's empty state offers Auto-fill -- Research Director researches the car's missing specs on the web and presents them as a proposal: each field shows your current value next to the proposed one, with a confidence level and sources. Untick anything you do not want, then click Apply changes to save the checked fields to your car. Web research can be wrong, so verify anything that matters before applying.

Fill from window sticker

Fill from window sticker in the panel header uploads a Monroney/window sticker and reads it. The review dialog shows your current value next to the extracted value for every field it found -- engine, transmission, drivetrain, fuel and MPG, curb weight, MSRP -- and lets you choose which to accept. Nothing is written until you apply.

VIN decode lives with the car's identity, under the Car details fold at the bottom of the panel: paste a 17-character VIN and click Decode to fill year, make, model, and trim from the public NHTSA database.

Brake pads

Track which brake pads are installed on your car, separated by front and rear axle.

Adding brake pads

Click Add Pads to open the brake pad form. Fields include:

When you install a complete pad set, TrackOut applies every pad in that set together. If something fails, the car stays as it was -- you will not end up with only some of the pads installed.

Pad life is shown on the car's Overview, on its own Brakes card -- front and rear remaining thickness, with a click to log a new measurement. It is deliberately not in the Setup section: a setup describes how the car is configured, and pad wear is what has since happened to it.

Parts check

The top of Build → Setup says whether the version you are looking at still matches the parts on the car. Every version saves a snapshot of the tires and brake pads fitted when it was recorded:

• A teal check -- v7 matches the parts on the car -- when nothing has changed since.
• A yellow warning naming what did -- Tires changed since v3: A052 Set A → A052 Set B (Apr 20) -- with Record as v4, which opens the new version's line in Versions with the change already written. The version saves only when you click Save as v4 there.
• Nothing, for a version saved before snapshots existed.

Choosing a setup

Build → Setup opens on the setup currently fitted to the car. Its title row names the version on screen -- Setup v7, the condition label, the setup's name, when the version was saved and the tires and pads it is pinned to ("pinned to Set A + RS19/RS29") (and "not on the car" when you are looking at a setup that isn't fitted) -- and holds:

• Compare -- shows the version before the one on screen, with what moved against its own predecessor. Back to current returns.
• Save as v_n+1_ -- opens the new version's line in Versions, for when the car itself changed.
• The ··· menu: the list of your setups (when you have more than one -- choosing another switches everything below it), New setup, Set as current (on a setup that isn't on the car), Edit setup, Share setup / Manage sharing, Stop sharing, Duplicate, Export, and Delete setup.

CSV cells that start like spreadsheet formulas receive a leading apostrophe so they open as literal text. Other tools reading the file may retain that apostrophe, including on signed measurement labels.

Starting a new setup

New asks four short questions:

• Where do the numbers come from? Start blank, or copy an existing setup and change what differs.
• What should it be called? A name, plus an optional Dry / Damp / Wet / Street label. Tap the label again to clear it.
• When was it measured? The odometer reading (prefilled from the car) and who measured it.
• Anything else. Whether to fit it to the car now, and who can see it. The first setup on a car is always the current one.

Alignment and corners

The Alignment and corners card reads one measurement per row, with the corners across -- FL, FR, RL, RR:

On a narrow screen the table scrolls sideways on its own -- the page never does.

Editing in place

Click Correct v_n_ in the card's header (or any number the sheet owns) and every such number becomes a box you can type into. Change the two that moved, then Save corrections. For when the car itself changed, Save as v_n+1_ on the title row opens a new version's line in Versions instead.

Only the newest version can be corrected. Pick an older one in Versions and the table reads Superseded: its numbers and their deltas show, but nothing is editable, because correcting it would rewrite the baseline the next version was measured against. Back to current returns to the newest.

Only the fields you actually changed are saved. Clearing a box removes that measurement rather than storing a zero. Ballast is editable too, in the totals strip -- it belongs to the sheet rather than to any one corner. Cross, front bias and left bias are worked out from the four corner weights, so they have nothing to type into.

The pressure rows are not editable here: Cold pressure and Hot target belong to the tire on that corner, and Hot · last run to the session that recorded it, so they are edited where they live.

What moved since last time

Under each measurement, a small signed figure shows how far it has moved from the previous version -- -0.3 on a camber, +5 on a corner weight. Unchanged numbers show nothing, so the two or three that did move are findable at a glance. The totals line and the springs, bars, and dampers card carry the same line.

The first version of a setup has nothing to compare against, so it shows no deltas.

Corner weights and the totals line

Below the table, a line carries the figures a corner-balance ticket quotes:

• Total -- the four corners added up.
• Cross -- the right-front plus left-rear diagonal, as a percentage of total. This is the wedge figure.
• Front bias and Left bias -- the front pair and left pair as percentages of total.
• Ballast -- any ballast recorded on the sheet.

Corner weights and ballast are entered in the alignment form alongside camber, toe, and caster.

Springs, bars, dampers

The Springs, bars, dampers card beside the table holds the rest of the mechanical setup, read from a suspension setup, with Front and Rear columns: spring rates (lbs/in), anti-roll bars and ride heights (mm), compression and rebound (clicks), then the aero -- rear wing (degrees), front splitter (a position label, because cars label it "Tab 3" or "Removed" rather than measuring it) and rake (mm) -- as single values. Only what you have recorded shows; the pencil edits it. All fields are optional.

Suspension setups are saved separately -- a Suspension picker under the sheet switches which one the card describes, marks the one On car, and offers New, Fit to car for any setup not on the car, and delete. Fitting captures the odometer the same way setting a setup as current does. The picker is available before the car has its first setup.

Sheet notes

Each sheet keeps a short list of typed notes, so the reasoning behind a change survives the weekend:

Pick a type, type the note, and press Add or Enter. Remove one with the x at the end of its row. Open in notes goes to the car's Notes card on the Overview, which is the place for anything longer than a margin note.

Runs

Under the sheet, beside the notes, sits what the setup achieved:

The tires on the car now have their own card under Build → On the car (see Tires and brakes on the car). The table's Cold pressure / Hot target rows still read the set on the car today, whichever setup is selected.

• Runs on this sheet -- every session logged against the version you are looking at, newest first, with the best lap of each. Underneath, the session count, the best lap set on it, and how much that improved from the first run. The list shows the newest 100 runs; past that the count reads as a floor ("100+"), the best lap is labelled as the best of that window, and the first-run comparison is dropped rather than computed off a partial history.

A session lands here when its track day was run on this sheet, or when the session itself names the sheet (a session that names a different sheet than its day follows its own). Planned sessions that have not run yet are not counted. A sheet with nothing on it yet says so rather than showing an empty table.

Versions

Every setup keeps a numbered history -- v1, v2, v3 -- of what the car was measured at and what you changed between them. The Versions card lists them newest first:

• Each row reads v_n_, the day it was saved, and what changed. The version on screen is tinted, with the best lap run on it.
• On car marks the version the car is running; any other offers Fit to car.
• + in the card's header (or Save as v_n+1_ on the title row) opens a line: type what changed ("Rear ARB R3 to R2") and click Save as v_n_ to record a new version. It starts from the previous version's numbers, so you only edit what actually moved.
• Details adds the odometer and who measured it, for a version that came from a shop visit rather than a click of rebound in the paddock. Those belong to the version, not the setup -- a later version does not inherit them, because the shop that measured v1 did not measure v2.
• Clicking a version's number shows it on the sheet, with its deltas against the version before it.
• Fit to car puts an older version back on the car -- useful when a change did not work out. It asks for the odometer, the same as fitting a setup does.

Version numbers are never reused. Delete v3 of three versions and the next one you add is still v4, so a note that says "aligned to v3" only ever means one sheet.

Changes made at a session

A change made at the track belongs to the session it was made at until you decide what it is. On the car's Driving tab, open a track day's "..." menu and choose Setup changes at S2 (one item per session that ran a setup) to note what you changed there; the changes are held on that session, and a yellow strip under its row shows a chip like S2 · v7 + 3 changes.

From that strip you decide:

• Save as v8 -- name the change, and it becomes the setup's next version, with the session re-pinned to it. A version never saves without a name.
• Discard -- drop the changes and stay on v7.
• Decide later -- keep the changes on the session for now.

If a save fails, a red banner above the session keeps your changes and the name you typed, with Try again.

At the track, the Paddock view does the same from your phone: queue changes while you log a session, and decide what they are when you leave.

Sharing a setup

Share setup in the ⋮ menu opens the sharing panel. A setup is private until you change that.

Below that, What travels with it controls how much a reader sees. Every section starts off:

The measurements always travel. Nothing that identifies you or the car ever does -- not your name, not the car, not the shop that did the work.

Logging setup service

You can also save or attach a setup while creating a service record. Choose Alignment Check or Suspension Check as the service type, then either enter new specs or select an existing saved setup. If you leave Make this the current setup checked, TrackOut fits that setup to the car as part of the same save.

The service record keeps a link back to the setup, and the Logbook row shows a compact setup chip so you can see which sheet was measured or installed during that shop visit.

Mileage tracking

When adding, editing, fitting, or deleting a setup, you can record the mileage at the time of the change. Entering one updates the car's odometer -- whether or not that setup is the one going on the car, because you measured the car at that reading either way. The odometer only ever moves forward, so a lower reading is ignored rather than winding the car back.

This keeps your car's mileage in sync with setup changes without needing to update it separately, and keeps maintenance history tied to what was on the car at each service.
