This stunning Downshift Blue Toyota GR Supra A90 was in the workshop this week for a custom MHD dyno tune on our in-house dyno.

Already an incredible platform from the factory, this Supra has been transformed with a fantastic selection of upgrades:

🔥 Whifbitz Hybrid Turbo
🔥 Wagner Tuning Chargecooler
🔥 FTP chargepipe kit
🔥 Infinity Design Carbon Intake Kit
🔥 Tomei Titanium Exhaust
🔥 Eibach 40mm Lowering Springs
🔥 Carbon Front Spoiler
🔥 Carbon Side Skirts
🔥 Carbon Rear Bumper Apron

After carrying out a bespoke dyno calibration, we achieved:

📈 Low Power Map: 445 WHP / 517 BHP
📈 High Power Map: 479 WHP / 556 BHP

The combination of the hybrid turbo, supporting modifications and custom MHD tune has created a seriously quick Supra with excellent drivability and an incredible soundtrack from the Tomei exhaust.

Another Toyota GR Yaris back in at Whifbitz recently for routine servicing and maintenance.

This car was previously with us last year for a range of upgrades including:
✔️ EcuTek remap
✔️ Nitron R1 coilovers
✔️ Eventuri carbon intake kit

This visit was all about keeping it in top condition with:

✔️ Motul engine oil service
✔️ Genuine Toyota oil filter
✔️ Genuine Toyota cabin filter
✔️ HKS spark plugs

Regular servicing is key to keeping these cars performing at their best, especially when they're modified and enjoyed properly.

It's always great to see customers returning to us to maintain their GR Yaris after we've carried out previous upgrades.

Another Toyota GR Yaris in at Whifbitz this week, this time for a clutch replacement after the original clutch started slipping.

Rather than replacing it with another standard setup, we fitted:
✔️ Xtreme Performance Heavy Duty Organic Clutch Kit
✔️ Xtreme Performance Flywheel
✔️ New Concentric Slave Cylinder (CSC)

The heavy-duty organic clutch retains excellent road manners while providing increased holding power, making it a great option for both standard and tuned GR Yaris models.

A strong, reliable upgrade and this GR Yaris is now back performing exactly as it should.

Is your GR Yaris clutch starting to slip? Get in touch with Whifbitz to discuss the best replacement options for your car.
