Customer Spotlight — CR15.SGR: The GR Yaris Build That Defined Madness

Discover how Cris (@cr15.sgr) turned his GR Yaris into a 700+ HP drag machine with X Shift Gearboxes.✔️From precise sequential shifts to record-breaking quarter-mile performance, see how engineering excellence meets extreme ambition.✔️

Sometimes, a project comes along that perfectly embodies what X Shift Gearboxes stands for — pushing boundaries.
That’s exactly what happened when Cris (@cr15.sgr) took his GR Yaris project to another level — and chose X Shift Gearboxes to make it all come together.

When Power Needed Control

This wasn’t just another tuned Yaris.
Cris’s car was built with one goal in mind — to dominate. A high-horsepower, drag-ready, precision-engineered weapon, pushing well into the 700 HP range (and capable of much more). But as any racer knows — power means nothing if you can’t control it.

That’s where X Shift stepped in.
The build demanded a transmission capable of brutal torque, instant shifts, and absolute reliability.
Our X Shift sequential gearbox with air-shift activation became the missing link that turned an already wild car into something extraordinary.

Performance That Spoke for Itself

When the car hit the strip, it didn’t just perform — it made headlines.
Cris and his GR Yaris recorded an 11.01-second quarter-mile at 132 mph (212 km/h), an incredible feat for a 1.6-liter, three-cylinder engine.

The setup featured:

SRD-tuned forged engine, Kelford B cams, Precision 5862 turbo, Syvecs ECU and 4WD controller, Nitrous injection
X Shift Sequential Gearbox (air-shift)

Every component came together seamlessly, and the gearbox quietly ensured that all that power was delivered smoothly, time after time.

A Build That Turned Heads

Cris’s Yaris went viral after being featured on Officially Gassed, drawing global attention to just how far this platform could be pushed.
The moment those lightning-fast shifts echoed through the video, it was clear — this build was something special. Comments poured in. Fans were stunned. Even seasoned tuners stopped and took notice.

And for us at X Shift Gearboxes, it was a proud moment. Seeing our technology support a build of this calibre reinforced the purpose behind our work — crafting gearboxes that bring ambitious visions to life.

The collaboration with Cris and SRD Tuning proved once again that success in motorsport and tuning is never about a single part — it’s about the synergy of smart engineering and team work.

Looking Back, Moving Forward

Today, the CR15.SGR build stands as one of the highlights in our customer stories — a shining example of what’s possible when cutting-edge engineering meets unstoppable drive.
We’re proud to have been part of that chapter and even prouder knowing that when drivers push limits, they trust X Shift Gearboxes to carry them through.
