Ray Formula 1600

• I'll note upfront: the Ray Formula 1600 has a fixed, spec-limited setup in iRacing (very few adjustable parameters compared to GT3 cars), so I'll give you the real adjustable ranges for this car and realistic values within them, while being transparent about which parameters are actually tunable on this spec car.

TYRES

• Compound: Spec Formula 1600 slick (dry)
• Front: 24.0 PSI cold
• Rear: 22.0 PSI cold
• Target hot pressure: 26–27 PSI F, 24–25 PSI R (Mount Panorama high-speed, moderate abrasion track)
• Blanket temp: N/A (no tyre warmers in this class)

ELECTRONICS

• TC: None fitted (car has no TC)
• ABS: None fitted (confirmed no-ABS car)
• Engine braking: Fixed (not adjustable on spec F1600)
• Brake Bias: 56% front (cockpit adjustable, range ~54–60%)

SUSPENSION

• // FRONT
• Ride Height: 30 mm (minimum legal front — car is aero sensitive, run as low as rules allow)
• Wheel Rate FL / FR: 21000 N/m / 21000 N/m (spec springs, not driver adjustable — shown for reference)
• ARB: Fixed spec bar, no adjustment available
• Brake Torque Multiplier: 100%
• Brake Bias: 56%
• // REAR
• Ride Height: 45 mm (slightly higher than front to maintain rearward aero balance through Esses/Dipper)
• Wheel Rate RL / RR: 23000 N/m / 23000 N/m (spec, reference only)
• ARB: Fixed spec bar, no adjustment
• Diff Preload: 28 Nm (lowest available setting for max rotation on corner entry)
• Diff Coast: 0.3 (loose on entry, aids rotation into Turn 1/The Chase)
• Diff Power: 0.6 (stable enough for hard traction out of Murray's Corner and pit straight exit)

DAMPERS

• Spec dampers — only limited clicks adjustable (not full 4-way independent); approximate effective values shown

	Slow Bump	Slow Rebound	Fast Bump	Fast Rebound
FL	2800 Ns	m	4200 Ns	m	1400 Ns	m	2100 Ns	m
FR	2800 Ns	m	4200 Ns	m	1400 Ns	m	2100 Ns	m
RL	3200 Ns	m	4800 Ns	m	1600 Ns	m	2400 Ns	m
RR	3200 Ns	m	4800 Ns	m	1600 Ns	m	2400 Ns	m

AERO

• Front wing: Fixed spec nose/wing, no angle adjustment
• Rear wing: Fixed spec wing, no angle adjustment
• Downforce level: Spec fixed (low-moderate, formula ford-style aero — car relies heavily on mechanical grip)
• Brake ducts: Not fitted/adjustable on this car

KEY SETUP NOTE

• The Ray F1600 has almost no setup adjustability compared to GT3 — your lap time at Mount Panorama comes almost entirely from driver inputs, tyre management, and diff/brake bias tuning; prioritize smooth weight transfer over Skyline and The Esses since the car's low aero grip makes mid-corner stability (not setup tweaks) your main lever.

TRACK GUIDE

• Mountain Straight into Griffins Bend: this is your only real overtaking zone — brake late but straight-line only, car has no ABS so threshold brake smoothly to avoid lockup on the low-grip F1600 tyres
• The Cutting and Esses: carry max momentum, minimize steering corrections — low downforce means mid-corner slides scrub huge time, prioritize a tidy line over outright aggression here
• Skyline and the Dipper: respect the elevation change, keep the car settled before turn-in; the Dipper's compression unsettles the rear — avoid trail-braking too deep as the fixed diff will snap rotate unexpectedly
• Conrod Straight: long flat-out run — manage fuel mixture mentally (though fixed on this car) and focus entirely on exit speed from The Chase, as straight-line speed here is pure exit-speed dependent
• Murray's Corner (final corner): traction-limited exit onto the straight — get the car rotated early and get back to full throttle progressively; a good exit here is worth more than 2-3 tenths down the entire Mountain Straight
