Corner Lab

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

The lap

Mobility Resort Motegi · Grand Prix

9 corners, 5 of which decide the lap. What each one asks of the car, and what you do about it.

The lapThe most stop-and-go circuit of the season: long straights terminated by heavy braking into tight corners, with almost nothing fast in between. Brakes and traction decide it.
Set up forTraction and braking stability above all. Drive ramp, rear mechanical grip, and a bias you can live with lap after lap.
Classic mistakeChasing rotation. It's low-grip and low-speed; a car set up to rotate just spins the rears on every exit.
Works hardestRears from traction, plus brake temperature

Corner by corner

Every corner on this layout

A marks the corners that decide the lap.

T1 Turn One

Heaviest stop on the lap

The biggest braking zone of the round, straight off the main straight into a tight right.

Technique
Get it stopped and get it pointed. Lose the exit here and you lose the whole first sector.
Demands
Braking-limited · Low speed — aero does little · Wants yaw on entry

T2 The S-Curve

Medium · direction change

A quick change of direction while the car is still settling from Turn 1.

Technique
One flowing input. Sawing at the wheel here costs you into the next braking zone.
Demands
Transient, not steady-state · Sustained mid-corner load · Wants a settled rear

T3 First Hairpin

Slow · traction critical

Very slow and tight, and it feeds a straight. All about getting the power down early without spinning up.

Technique
Sacrifice entry for exit. Wait for the car to point before committing to the throttle.
Demands
Low speed — aero does little · Traction-limited · Exit-phase limited · Wants yaw on entry

T4 Turn Four

Medium right

A linking corner that sets up the V-Corner. Easy to lose time in, hard to gain any.

Technique
Straighten it as much as the track allows and protect the entry that follows.
Demands
Sustained mid-corner load · Front grip limited

V The V-Corner

Slow · very technical

Motegi's signature corner — extremely slow and tight, with a big time loss if the car won't rotate.

Technique
Patience. The corner keeps turning; get greedy on entry and you wash out to the exit kerb.
Demands
Low speed — aero does little · Wants yaw on entry · Traction-limited

90 90-Degree Corner

Slow right · square

Exactly what the name says: a square right-hander with heavy braking and a short exit.

Technique
Brake straight, turn late, and get the car square before you pick up the throttle.
Demands
Low speed — aero does little · Braking-limited · Wants yaw on entry · Traction-limited

HP Hairpin Curve

Slow hairpin

Slow hairpin feeding the downhill straight. Another exit-dominated corner on a lap full of them.

Technique
Late apex and early power. Everything here is about the straight that follows.
Demands
Low speed — aero does little · Traction-limited · Exit-phase limited · Wants yaw on entry

DH Downhill Straight complex

Medium · downhill

The run down toward the final sector, with the car light under braking on a downhill grade.

Technique
Be settled before you brake. The downhill will find any instability you've left in the car.
Demands
Braking-limited · Wants a settled rear · Transient, not steady-state

VC Victory Corner

Final corner · onto the straight

The last corner, feeding the main straight. The single most valuable exit on the lap.

Technique
Textbook sacrifice-entry-for-exit. Everything you gain runs the full length of the straight.
Demands
Traction-limited · Exit-phase limited · Low speed — aero does little · Rear grip limited
