Road Drift Tuning Guide

RWD Builds — Tarmac — Swap AWD → RWD before tuning — Diff Accel is the most impactful setting

Tires
Drift
Required — always use
Front PSI: 32–35
Higher = easier initiation
Rear PSI: 30–33
Lower = more predictable slip
Front higher than rear
Promotes oversteer tendency
Car won't sustain slide → confirm Drift compound is equipped · Need more initiation → raise front PSI 1–2

Hard to initiate → narrow front or widen rear · Can't hold angle → widen rear 5–10mm
Gearing
Alignment
Camber
Front-3.5° to -5.0°
Rear0° to -1.0°
Front grip lost during catch → more negative front camber · Rear unpredictable → move rear camber closer to 0°
Toe
Negative = in · Positive = out
Front+0.2° to +0.5°
Rear0° to -0.2°
Hard to initiate → add more front toe-out · Rear washing out → add small rear toe-in (-0.1°)
Caster
Angle6.5° to 7.0°
Steering slow to return after slide → raise caster · Wheel not self-centering → raise caster to upper range
Antiroll Bars
Stiffer front = easier initiation · Softer rear = holds slide angle longer
Front40 – 55
Rear15 – 25
Hard to sustain angle → stiffen front ARB · Rear snapping back mid-slide → soften rear ARB
Springs
lbs/in — Ride Height: minimum available
Rear = Front + 20–30 lbs/in · Pick front by weight, add ~25 for rear
Light (<2,600 lbs)F 300–500
R 350–550
Sport (2,600–3,400)F 425–650
R 475–700
Muscle (3,400–4,200)F 575–850
R 625–900
Heavy (4,200+ lbs)F 750–1050
R 800–1100
Car rolling too much mid-slide → stiffen springs · Rear light at high angle → stiffen rear springs
Rebound
Controls extension speed · Stiffer front = resists dive · Stiffer rear = resists squat
Front8.0 – 10.0
Rear6.0 – 8.0
Slow initiation → lower front rebound · Rear snapping back → lower rear rebound
Bump
Controls compression speed · Set bump first · Rebound = bump × 2
Front5.0 – 7.0
Rear3.0 – 5.0
Front diving too fast on initiation → raise front bump · Rear snapping out → lower rear bump
Differential Types
StockLow class / saves PI — limited or no tuning available
RaceCircuit & road racing — full accel/decel tuning range
DriftRoad drift — high lock bias, tuned for sustained slides
OffroadOffroad drift — loose surface compliance, full tuning range
RallyMixed events — road & dirt compromise
DragStraight line only — maximum lock, launch focused
Can't sustain slide angle → confirm Drift diff is equipped before adjusting accel/decel
Aero
FrontMinimum
RearMinimum
High speed buildsSmall rear wing only
Unstable at high speed → add small rear wing only · Aero killing slide angle → return to minimum
Brake
Balance35 – 45%
Pressure90 – 100%
Spinning out on entry → raise brake balance % toward 50 · Hard to flick initiate → lower brake balance %
Differential
Acceleration85 – 100%
Deceleration0 – 15%
Start pointAccel 90% / Decel 10%
Can't hold angle → raise accel · Hard to initiate under braking → lower decel
Quick Adjustments
  • Won't hold angleRaise diff accel toward 100%
  • Hard to initiateLower diff decel toward 0%
  • Snapping straightSoften rear ARB / lower rear springs
  • Twitchy / unstableAdd slight rear toe in (+0.1°)
  • Understeer on entryMore front camber / lower brake balance %
  • Too aggressive spinLower diff accel to 80–85%
