Corner Lab

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

The lap

Lime Rock Park · Full Course

6 corners, 3 of which decide the lap. What each one asks of the car, and what you do about it.

The lapSeven turns and under a minute a lap, which makes it unforgiving in a way long circuits are not: there is nowhere to make time back. Momentum is everything, and a car that will not hold a line through Big Bend is slow everywhere.
Set up forA front end that holds a long steady load through Big Bend, then a rear that stays settled over the Uphill crest and down through Diving Turn.
Classic mistakeSetting up for braking stability. There is almost no braking here — the lap is decided by sustained cornering and by commitment over blind crests.

Corner by corner

Every corner on this layout

A marks the corners that decide the lap.

T1 Big Bend

Fast right · long

A long, fast right taken almost flat, and the front tyre is loaded for far longer than it feels.

Technique
One steering input and hold it. Correcting mid-corner scrubs the front and you pay for it all the way down No Name.
Demands
High speed — aero is live · Sustained mid-corner load · Front grip limited · Wants a settled rear

T2 The Left-Hander

Medium left · off-camber

The only left on the lap, and it falls away from you on exit.

Technique
Get the car rotated early. Running wide here puts two wheels on the grass with no room to recover.
Demands
Wants yaw on entry · Low speed — aero does little · Exit-phase limited

T3–4 The Esses

Quick left-right · uphill

A short uphill flick that sets up the whole back half of the circuit.

Technique
Straighten it out and use the kerb. Fighting the direction change costs more than the kerb does.
Demands
Transient, not steady-state · Kerbs are part of the line · Turn-in transient

T5 The Uphill

Medium right · blind crest

Blind and rising, with the car light over the crest just as you want to commit.

Technique
Take it on faith and a reference on the horizon. Lifting at the crest unsettles the rear exactly when you cannot afford it.
Demands
Compression or crest loading · High speed — aero is live · Wants a settled rear · Aero platform sensitive

T6 West Bend

Fast right

Quick and committed at the top of the circuit, leading to the drop back down.

Technique
Carry the speed. The lap time here is decided by how early you can be back to throttle.
Demands
High speed — aero is live · Sustained mid-corner load · Wants a settled rear

T7 Diving Turn

Fast right · downhill

Downhill and onto the main straight, so every mistake is multiplied by the length of the straight that follows.

Technique
The rear goes light as the road drops. Be committed but be smooth — this is the corner that decides the lap.
Demands
High speed — aero is live · Rear grip limited · Wants a settled rear · Exit-phase limited

Corner names and numbering follow common usage; some circuits number differently between layouts.
