DAMPERS

AERO

• Spoiler angle: 11° fixed-rule package (Xfinity Homestead spec)
• Downforce level: Low-drag oval trim, no front splitter adjustment available
• Brake ducts: Fully open (max cooling) — Homestead heat and long green runs punish brake temps

KEY SETUP NOTE

• Homestead's variable banking (18–20° in turns, progressive) means the car's cross-weight and left-side wedge must stay slightly tighter than a typical mile-and-a-half — run wedge around 58–60% cross to prevent the rear from going loose mid-corner as tyres fall off on long runs; this car will push on entry but go free off-throttle exiting Turns 2 and 4 as stagger builds heat — anticipate the transition rather than react to it.

TRACK GUIDE

• Turns 1-2 and 3-4 are variable-banked, so your entry speed must be carried higher than it looks safe — trust the banking, brake later than instinct dictates, lift-and-roll rather than stab the brake.
• Traction zone off Turn 4 is the biggest lap time gain — get back to throttle progressively, as this car is sensitive to rear squat on worn tyres; too aggressive too early will snap the rear loose.
• Manage left-side tyre temps carefully — Homestead's abrasive surface combined with aggressive driving accelerates right-rear wear; short-shift exits mid-stint to preserve rear grip for the final 20 laps.
• Fuel/tyre window: plan for a gradual tightening of your line as the run goes on — the car will want more bottom/middle grip as stagger washes out, so widen your entry arc slightly rather than fighting a push.
• Lap time is won in the middle of Turns 2 and 4 — minimum speed through the center of the corner on a stable platform matters more than outright entry speed; sacrifice a little entry to protect rotation at mid-corner.
