Formula Vee - Classic

TYRES

• Bias-ply spec radial, Front: 13.0 PSI cold, Rear: 14.5 PSI cold. Optimal operating window: 70–85°C for peak grip — this compound loses grip sharply above ~90°C, so avoid over-heating rears through Old Hall/Knickerbrook.

ELECTRONICS

• TC: N/A (none fitted)
• ABS: N/A (none fitted)
• Brake magic / engine braking: N/A — no adjustable engine braking, fixed 4-speed non-synchro gearbox
• Brake Bias: F 60% / R 40%

SUSPENSION

• // FRONT
• Spring Perch Offset: 4 turns from full soft (raises front slightly to sharpen turn-in for Island and Cascades rotation while keeping ride height legal over Knickerbrook crest)
• ARB: 19.05mm (3/4 in, stiffest available) — maximises front roll resistance, forces rear to do less work, critical for stability under Cascades blind entry load
• // REAR
• Spring Perch Offset: 2 turns from full soft (slightly softer relative to front to load the swing axle progressively, reducing snap oversteer under Cascades and Old Hall)
• Pushrod Offset: 3 turns from full soft (lowers rear slightly versus front to promote a nose-up rake, stabilizing high-speed direction changes at Knickerbrook and Old Hall)

DAMPERS

• N/A — not exposed as an adjustable parameter on this car's setup sheet in iRacing.

AERO

• No wings or downforce adjustment on this car. Rake set via Spring Perch Offset / Pushrod Offset combination above — slight nose-down static attitude (front lower than rear) to maximize front bite for Cascades/Island while retaining rear planted stability at speed.

KEY SETUP NOTE

• With a solid swing-axle rear and zero rear ARB, all your roll stiffness lives at the front — this means rear stability at Cascades is governed almost entirely by ride height/rake (Spring Perch + Pushrod Offset), not by any roll bar. Keep the rear slightly lower/stiffer relative to front to prevent swing-axle jacking and snap oversteer on the blind, downhill, high-speed entry — this is the single biggest lap time and survival factor on this track.

TRACK GUIDE

• Cascades (T1): trust the rear setup, brake in a straight line before turn-in, ease into throttle only once rotation is confirmed — this corner punishes swing-axle jacking brutally, be smooth not aggressive on initial turn-in despite the "attack" mandate.
• Shell Oils (T3): brake late but in a straight line, get the car rotated early so you can apply full throttle from apex — traction out is worth more than entry speed here given the low torque.
• Island (T5): use the sharper front-end turn-in from the stiff front ARB and raised front spring perch to rotate late, then get straight and full power early — swing axle rear means avoid trailing throttle oversteer.
• Knickerbrook (T7): committed, stable through the crest — the nose-up rake keeps the rear planted; lift only if the car goes light, otherwise carry maximum speed through the S.
• Druids (T9) and Fosters (T12): both reward early, progressive throttle application over outright rotation — with only 69hp, exit speed onto the following straight is where lap time is truly won or lost, not mid-corner speed.
