GR Supra A90

The GR Supra is a short-wheelbase, torque-rich coupe that is quick straight out of the box and very approachable for a turbo car. On track its limits are thermal rather than mechanical: in hot weather the stacked cooling package can push the car into reduced power, and the stock brakes and pads give up after several hard laps. Rear camber is adjustable from the factory, but the front needs camber plates for a proper track alignment.

These are starting points gathered from the sources listed at the bottom, not a guarantee. Cars, tires and parts vary: have a reputable alignment shop set your car, check factory specs for road use, and change one thing at a time.

01On track

Strengths
  • +Huge mid-range torque from the B58; easy to drive fast without chasing revs
  • +Short wheelbase gives a responsive, agile car on tight tracks
  • +Factory-adjustable rear camber
  • +Strong aftermarket for cooling, brakes and alignment parts
Watch out for
  • −Heat soak and reduced power on hot days in repeated sessions
  • −Stock pads fade when pushed hard
  • −Little front camber without aftermarket plates
  • −Short wheelbase can make it nervous on fast lift-off or curb strikes

02Alignment

Where to start the alignment.

Owner consensus and parts-maker data. Front plates (Vorshlag, Ground Control) are adjustable at the track. One owner reported about -2.5° to -2.6° front as the limit before rubbing on his setup. No reputable source gave a complete track spec, so treat these as hardware limits rather than targets.

Hot pressure target
≈34–36 psi hot for 200TW / max-performance summer tires; ≈30–32 psi hot for R-compounds

No Supra-specific figure was found. Tire Rack's 2026 study found most streetable track tires fastest at 34–36 psi hot and saw oversteer and slower laps above 36 psi. [8] Work out your cold pressure →

Brake pads

Track compounds such as Endless MX72 (used on a specialist's A90 build), G-Loc R10/R12 (owner choice) or a maker's A90 track pad package

Brake fluid

High-boiling racing fluid such as Motul RBF 600 (312°C dry / 205°C wet) or Castrol SRF

Pad recommendations here come from tuners and owners rather than independent testing. Add brake cooling alongside pads. [4,13,14,15]

04Known issues on track

Fix these before they find you.

  • Heat soak and limp mode on hot days

    Owners who run the car hard in triple-digit ambient temperatures report reduced power and sluggish shifts after several sessions, blamed on a tightly stacked cooling package that cannot recover between runs. Upgraded heat exchanger, auxiliary radiators and transmission oil cooling are the common fix. (The source describes the transmission as a DCT; the 3.0 automatic is a torque-converter unit, but the transmission-cooling point stands.) [1]

  • Oil temperatures

    One owner's logged session on a mostly stock car in full sport mode saw oil stay at or below about 114°C (237°F). Log your own temperatures before buying cooling parts; heat problems on this car tend to show up first as heat soak and power reduction. [2]

  • Rear camber eccentric bolts can slip

    The factory rear camber eccentric bolts can shift under hard loads and change rear camber without you noticing. Rear camber also increases as the car is lowered. Recheck the alignment after the first hard event, or lock it with shims or adjustable arms. [3]

  • Brake fade on stock pads

    Owner consensus is to switch to a street/track or track pad and add brake cooling rather than general engine cooling as the first thermal upgrade for track days. [4]

05Modification roadmap

In the order that pays off.

  1. 0
    Safety & reliability first

    Heat and brakes first

    • Track pads, racing fluid and brake coolingStock pads fade after several hard laps.
    • Logged temperatures (oil, coolant, intake)Decide on cooling parts from data, not guesses.
    • Upgraded heat exchanger / auxiliary radiators for hot climatesPrevents power reduction in back-to-back sessions.
  2. 1
    Tires & alignment

    Tires and alignment

    • Front camber platesThe front has almost no stock camber range.
    • Rear camber shims or adjustable armsStops rear camber drifting on the factory eccentrics.
    • 200TW tireLarge grip gain over the OE summer tire on track.
  3. 2
    Suspension & brakes

    Suspension

    • Coilovers and corner balanceControls the short-wheelbase chassis over curbs and on lift-off.
  4. 3
    Power & aero

    Power last

    • ECU tune and intake/exhaustEasy power on the B58, but every extra horsepower adds heat and brake load.

Estimates from a simplified point-mass lap simulation of GR Supra A90 / A91 (3,401 lb, 335 hp) on a fictional circuit, with generic effects for each upgrade category. Good for comparing options on the same car, not for predicting your lap time. Real results depend on the driver, the exact parts, the track and the conditions. Durability starts lower on this car because of its known issues: heat, brake fade.
