DAMPERS

AERO

• No adjustable wings on Ray FF1600 (fixed-spec bodywork, minimal aero device). Ride heights above are the primary aero-platform tuning tools — front kept low and stiff for turn-in bite, rear slightly higher for stability under brakes into Turn 1 and Turn 6.

KEY SETUP NOTE

• This car has essentially no aero adjustability, so lap time comes almost entirely from mechanical grip and ride-height rake — run the front as low as the minimum will allow to maximize front bite for Oran Park South's tight, low-speed hairpins (Turn 2, Turn 6), while keeping just enough rear ride height to prevent snap oversteer over the mid-corner bumps on exit of Turn 4.

TRACK GUIDE

• Turn 1 (fast right-hander off the front straight) rewards late, trail-braked entry — carry min speed high and let the car rotate on trail-brake rather than lifting early, since the FF1600 has strong front grip under trail braking.
• The Turn 2 hairpin is the biggest time-loss/gain corner — brake as late as possible in a straight line, rotate hard on entry with a dab of trail brake, and prioritize a clean, early throttle application over apex speed since the following straight is long.
• Esses through Turn 4-5 are flowing and rhythm-based — minimize steering corrections, use curbs aggressively on exit to widen your line and carry speed, this is a "commitment" section for outright pace.
• Turn 6 hairpin before the final straight is the most important exit of the lap — sacrifice entry speed slightly to protect traction on exit, as this feeds the longest straight into Turn 1.
• Overall lap time is won through minimum-speed discipline in the two hairpins (T2, T6) rather than outright cornering speed elsewhere — this light, low-power
