622BHP Toyota GR Supra A90 Upgrades & Service

/ by

We recently had this stunning Toyota GR Supra A90 in for some serious upgrades and routine servicing, now running an impressive 622bhp. You can read more about this Supra we’ve built by clicking here.

Wavetrac LSD Installation

One of the main upgrades was the newly released Wavetrac limited-slip differential (LSD). This completely removes the factory electronic differential (E Diff), transforming how the car puts power to the ground. To finish the job properly, we also coded out the E Diff in the ECU, ensuring everything works seamlessly with the new mechanical LSD. The difference is especially noticeable at high power levels like this one, making traction and control far more predictable and rewarding.

Tyres & Brakes

To keep things planted, we fitted a fresh set of Continental SportContact 7 tyres in 305/30×19 on the rear. For stopping power, we installed Endless MX72 brake pads, known for their strong performance both on the road and track.

Service Work

Alongside the upgrades, we carried out a full service which included:

  • Engine oil change
  • Cabin filter replacement

This ensures the Supra is not only powerful but also reliable and ready for many more spirited miles ahead.
