DAMPERS

AERO

• Front Splitter: Level 2 (low-medium, minimize drag for banking)
• Rear Wing: 3 clicks (low downforce setting — Daytona oval priority)
• Downforce Level: Low overall — prioritize top speed on banking
• Brake Ducts: Front 2 / Rear 2 (moderate cooling, long stint management)

KEY SETUP NOTE

• This setup leans toward low drag and rear stability over outright mechanical grip — on Daytona's oval banking the car is loaded heavily by the 31° banking itself, so excess rear ARB or wing will only cost top speed on the backstretch without adding meaningful rotation; the real lap time differentiator is confident, stable entry into the Bus Stop and clean traction out of the infield hairpins.

TRACK GUIDE

• Brake late and hard into Bus Stop chicane entry — trail brake deep but get off the pedal early to rotate the car onto the inside kerb without unsettling the rear.
• Use the chicane kerbs aggressively (both entry and exit) — the BMW M4 GT4 handles curb strikes well with this damper setup, use them to shorten your line.
• On the infield technical esses, prioritize smooth minimum-speed carry rather than late apex braking — traction out is more valuable than one-tenth on entry.
• Through the oval banking (T3/T4), stay committed flat-out — the banking does the grip work; focus on holding your line low to preserve momentum onto the backstretch.
• Final chicane before pit straight is the most important traction zone on the lap — unwind the wheel early and get full throttle down cleanly, as the backstretch and banking exit speed depend on it.
