The GR Supra A90 and A91 uses BMW's 3.0-litre B58, so a lot of the upgrade path is shared with the M340i and M240i. Here's where we'd start, depending on whether you want more power, better looks or more consistency on track.
Power: tune and downpipe
The B58 makes big gains from a tune alone. A downpipe is the usual next step: it frees up the exhaust straight after the turbo and pairs with a more aggressive map. There are two versions:
- Project Gamma B58 downpipe, listed for both Gen1 and Gen2 B58 fitments
- Project Gamma catted 200-cell downpipe, for cars that need to keep a catalytic converter
Consistency: cooling
Tuned Supras get hot, especially on track or on a 40-degree Adelaide afternoon. When the charge-cooling water heats up, the car pulls timing and power drops off. The Project Gamma chiller system for the Supra uses the air conditioning to cool that water and keep intake temperatures stable, run after run.
Looks: lighting
Lighting is one of the most visible changes you can make to an A90, and it's fully reversible:
- FT-1 style LUXX-Series LED tail lights, inspired by the FT-1 concept
- Heritage tail lights, a nod to the round lights of earlier Supras
- LED logo door lights, a small detail you see every time you open the door
Looks and grip: aero
ADRO makes the most complete aero range for the Supra, from a front lip on the factory bumper through to a full widebody. The key choice is whether you keep the factory front bumper or convert to ADRO's. The lips, canards and undervanes are made in separate versions for each, so decide on the bumper first.
- Street: a carbon front lip, side skirts and a rear spoiler
- Track: the ARD prepreg race lip, canards, undervanes and race diffuser, which are designed to work together

Handling
Suspension Secrets adjustable front drop links let you remove sway-bar preload after lowering the car, so it behaves the same turning left and right.
Where to start
| If you want | Start with |
|---|---|
| More power | Tune, then downpipe |
| Track consistency | Chiller system, then aero |
| A different look | Tail lights, front lip, side skirts |
| Better handling | Drop links and a proper alignment |
