Corner Lab

Your car, the corner, and what it's doing there — the setup changes worth trying, in order.

The lap

Circuit de Spa-Francorchamps · Grand Prix Pits

11 corners, 6 of which decide the lap. What each one asks of the car, and what you do about it.

The lapThe classic downforce compromise at the biggest scale on the calendar. Eau Rouge and Pouhon want wing; the Kemmel straight punishes every click of it.
Set up forMinimum wing that survives Pouhon and Blanchimont, then protect the platform through Eau Rouge with ride height and heave — not with wing.
Classic mistakeAdding wing to fix Eau Rouge. If the car goes light there it's usually ride height or bump stops, and wing just makes you slow down Kemmel too.

Corner by corner

Every corner on this layout

A marks the corners that decide the lap.

T1 La Source

Slow hairpin

Tight downhill hairpin onto the run to Eau Rouge. Its exit feeds the most important sequence on the lap.

Technique
Get it stopped, rotated, and the power down. Don't over-slow it chasing a perfect apex.
Demands
Low speed — aero does little · Wants yaw on entry · Traction-limited · Braking-limited

T2–4 Eau Rouge / Raidillon

Fast · compression · blind

The biggest compression the car will see all season, taken blind uphill at enormous speed.

Technique
Committed and straight. If the car bottoms or goes light here it's a platform problem, not a balance one.
Demands
Compression or crest loading · Aero platform sensitive · High speed — aero is live · Wants a settled rear

T5 Les Combes

Braking · right-left chicane

Heavy braking at the end of Kemmel into a right-left over kerbs. The main overtaking spot on the lap.

Technique
Late but straight. Use the kerb on exit and be settled for Malmedy.
Demands
Braking-limited · Kerbs are part of the line · Wants yaw on entry

T7 Malmedy

Medium left

The second half of the Combes complex, taken while the car is still unsettled.

Technique
Flow it. This is one movement with Les Combes, not two separate corners.
Demands
Sustained mid-corner load · Transient, not steady-state · Front grip limited

T8 Rivage

Slow right · downhill

Tight, downhill and off-camber on entry, with the car light under braking.

Technique
Brake earlier than instinct says. The camber will take the front away if you rush it.
Demands
Low speed — aero does little · Braking-limited · Wants yaw on entry

T9 Turn Nine

Medium left · downhill

A quick left dropping downhill toward Pouhon, easy to compromise.

Technique
Get straight early — you need the car settled before Pouhon's entry.
Demands
Sustained mid-corner load · Transient, not steady-state

T10–11 Pouhon

Long fast double-left

Long, fast, double-apex left taken downhill. A loose rear here is genuinely frightening.

Technique
One committed input. Correcting mid-corner loses the whole sequence that follows.
Demands
High speed — aero is live · Rear grip limited · Sustained mid-corner load · Aero platform sensitive

T12–13 Fagnes

Medium chicane

A quick right-left that demands a clean direction change on a car still loaded from Pouhon.

Technique
Rhythm over aggression. Use the kerb but stay flat on landing.
Demands
Transient, not steady-state · Kerbs are part of the line · Sustained mid-corner load

T14–15 Stavelot

Fast right · double apex

Long and fast, and its exit feeds the run to Blanchimont — one of the most valuable exits on the lap.

Technique
Be patient with the first apex so you can be greedy with the second.
Demands
High speed — aero is live · Front grip limited · Exit-phase limited

T17–18 Blanchimont

Very fast left

Near-flat at very high speed. Pure aero and platform confidence.

Technique
Hold it. If you're lifting here, the setup rather than the driving is the problem.
Demands
High speed — aero is live · Wants a settled rear · Aero platform sensitive

T19 Bus Stop

Chicane · big kerbs

The last chance to make or lose a lap, on aggressive kerbs, straight onto the pit straight.

Technique
Ride the kerbs and land flat. Exit feeds the whole start/finish straight.
Demands
Kerbs are part of the line · Braking-limited · Bumpy surface
