Engineering & Parts

LIVE damage, repair, parts and the F9 panel EXPERIMENTAL the Workshop, competency and Build

Engineering is its own panel: F9, docked to the right side of the screen. It never goes full screen and never takes your keyboard.

Damage

Damage is persistent and weighted by what it costs to put right: chassis 60%, body 25%, glass 6%, lamps 4%, tyres 3%, panels 2%. It is not the worst single dent. Damage survives a reconnect and lasts for the whole Race Week.

Repair

SERVICE in F9 shows condition by area before you choose a job.
Self repair costs materials only. Your own hands don't charge labour.
A workshop quotes materials and labour. Route Me There navigates to the suggested shop.
Workmanship rolls per section (grip, drive, brakes, drag). Each can come out better or worse. Your restoration skill moves the odds, and a botch affects only that section. The result is written onto a job sheet, one section at a time, and stamped. Read it.
NPC teams repair with the same model, and pay for it.

Parts

Parts are serialized components: one physical part with an identity, bought from Market stock (the PARTS view) and fitted to a machine you own.

Fitment rules are real. A part that doesn't fit says so before you buy it.
Parts wear with distance. Tyre compounds (hard/medium/soft) are not in yet.
Fitted parts travel with the car; loose parts can be stored and traded on the Exchange.

The Workshop EXPERIMENTAL

The F9 WORKSHOP tab is one bench for four kinds of engineering, usable anywhere:

Job	What it does
Tear down	Consumes a specimen part and reveals what it is, in stages, as far as your reverse-engineering skill reaches. The knowledge stays with you.
Fabricate	Builds a prototype from what you know. It can come out poor, neutral or junk, and junk is kept (and can't be mounted).
Promote	Turns a working prototype into your own immutable design.
Run	Builds one to three units of your design. Your production skill sets the reject rate. You can list a unit on the Base Market; the buyer pays you.

Every bench job builds your engineer competency, shown in words from Untrained to Master, never as raw numbers.

The F9 BUILD tab is reserved for player-built infrastructure and is not designed yet; on some clients it reports that Build is not running.
