Why the Supra is Such a Special Tuning Car
The A90 GR Supra shares its BMW B58 engine, ZF 8-speed gearbox, and platform with the BMW Z4 M40i. This means it benefits from the exact same tuning expertise we apply to the entire BMW B58 range. The Supra's lighter weight and rear-wheel drive layout make every power gain feel even more dramatic than in heavier BMW models.
- → Factory power: ~340BHP — Stage 1 takes it to 440-450BHP
- → Same B58 engine as BMW Z4 M40i, M340i, M440i, and more
- → RWD layout makes every BHP feel more exciting
- → Free adjustments on all tuning work
