Suspension

[!] Understeer on turn-in and potential oversteer on corner exit.

Stiffen the rear suspension and slightly soften the front to improve turn-in response and balance the car. Lowering the car will also help reduce body roll and improve stability.

Front Ride Height

-5mm

Rear Ride Height

-5mm

Anti-Roll Bars

[!] Oversteer on corner entry/mid-corner and understeer on exit.

Increase front ARB stiffness to help the car rotate more easily into corners. Slightly decrease rear ARB stiffness to reduce oversteer on exit.

Front ARB

Increase by 1-2 points

Rear ARB

Decrease by 1 point

Differential

[!] Excessive wheelspin on corner exit and unpredictable oversteer.

Increase initial torque for better traction off the line. Increase acceleration sensitivity to help the rear wheels lock together under throttle, reducing wheelspin. Deceleration sensitivity can be kept moderate to avoid excessive snap oversteer when lifting off.

Initial Torque

20

Accel Sensitivity

40

Decel Sensitivity

20

Brakes

Slightly bias towards the front to help with turn-in and prevent rear lock-up, especially when trail-braking.

[!] Track Analysis — Michelin Raceway Road Atlanta Standard

Where and how to drive on this track for the best lap time.

Turn 1 - Big Bend

4th or 5th

High-speed, downhill sweeping right-hander

Brake firmly but smoothly on entry while turning in. Aim for a late apex to maximize exit speed and set up the Esses. Use the full track width on exit without running wide into the grass.

The Esses (Turns 2-5)

4th or 5th

High-speed, flowing left-right-left-right complex with significant elevation changes

Commitment and smooth inputs are vital. Turn 2 (left) is critical for flow; aim for an early apex to open up Turn 3. Maintain momentum through the complex, using minimal steering inputs. Be aware of the downhill compression and subsequent lift over the crest. Avoid aggressive curb use that can unsettle the car.

Turn 10a/b - The Chicane

3rd or 4th

Fast left-right chicane, downhill entry

This is a major braking zone. Brake hard and turn in sharply for 10a (left), using the inside curb to straighten the line for 10b (right). Be precise to avoid running wide on the exit of 10b, as it compromises the entry to the final turn. Smooth throttle application is key here.

Turn 12 - Final Turn

3rd or 4th

Long, sweeping right-hander, uphill exit onto the main straight

This corner is crucial for lap time. Brake smoothly and turn in, focusing on a very late apex. The goal is to get the best possible drive out onto the main straight. Be progressive with the throttle as the car climbs the hill to avoid wheelspin or oversteer. Use the full track on exit.
