Toyota GR Supra A90/A91 Performance Parts: UK Upgrade Guide

The modern Toyota GR Supra combines rear-wheel drive, turbocharged performance and enormous aftermarket support.

For owners of A90 and A91-generation cars, the number of available upgrades can be overwhelming.

Here is how to build the car logically.

Air Intake

A performance intake is a popular first modification because it can improve induction sound while supporting future airflow requirements.

Options range from filters and intake pipes to complete carbon-fibre systems.

Exhaust

A performance exhaust gives the Supra a more distinctive character.

Available systems include:

• Rear sections
• Cat-back exhausts
• Valved systems
• Performance downpipes

Pay close attention to year, engine and emissions configuration before ordering.

Cooling

Heat management becomes increasingly important when a turbocharged vehicle is modified.

Depending on the car and intended power level, cooling upgrades can become important supporting components for sustained performance.

ECU Tuning

Modern Supras have significant tuning potential, but calibration should always be matched correctly to the installed hardware.

Avoid buying parts simply because somebody else’s vehicle uses them.

The requirements for your calibration may differ.

Suspension

Owners wanting a lower stance can consider springs, while coilovers provide a broader range of adjustment.

Other useful chassis components include anti-roll bars, braces and adjustable suspension arms.

Braking

Performance brake pads are a sensible starting point for owners driving their Supra enthusiastically.

More demanding use may justify upgraded discs, brake fluid, hoses and larger braking systems.

Wheels and Tyres

Performance tyres can transform how effectively the car uses its available engine and chassis performance.

When changing wheels, verify:

• Diameter
• Width
• Offset
• Centre bore
• PCD
• Brake clearance
• Tyre dimensions

Do not buy wheels based on diameter alone.

Build a Balanced Supra

A sensible approach is:

Maintenance → Tyres → Brakes → Intake → Exhaust → Cooling → ECU Calibration → Suspension → Further Power

A balanced build allows the chassis, brakes and tyres to keep pace with any additional power.
