And just quickly before we begin! Make sure you add your vehicle to our garage function on our website! It's the ultimate convenience while you find that dream GR mod.
What are GR Corolla and GR Yaris Mods?
A GR Corolla or GR Yaris mod is an aftermarket upgrade designed to improve the performance, handling, style, or functionality of these Toyota hot hatches. These modifications range from turbochargers and suspension kits to aesthetic enhancements like body kits and custom lighting, allowing owners to personalise and optimise their vehicles for specific needs and preferences.
GR Corolla: The Everyday Thrill Ride
The GR Corolla is what happens when Toyota decides “good enough” isn’t enough. With a turbocharged 1.6-litre 3-cylinder engine delivering 221kW of raw power, this hot hatch sneers at the mundane. Its GR-FOUR all-wheel-drive system ensures you own every curve, while an intelligent 6-speed manual lets you command the chaos with style.
- Torque: 370Nm—because subtlety is overrated.
- Grip: Rally-bred all-wheel drive keeps you glued to the road, or dirt, or snow—whatever you throw at it.
- Purpose: Equal parts daily driver and adrenaline generator.
The GR Corolla doesn’t just take you places—it drags you headfirst into the thrill of getting there.
GR Yaris: A Rebel in a Compact Suit
Toyota didn’t just build the GR Yaris; they unleashed it. This compact powerhouse delivers heart-pounding performance with a 1.6-litre, turbocharged 3-cylinder engine that laughs at the laws of physics. Its GR-FOUR all-wheel-drive system grips the road like a bear hug, and its featherweight body, complete with a carbon-fibre roof, dances through corners with the grace of a rally champ.
- Power-to-Weight Ratio: 156kW/tonne. Because why not?
- Chassis: Rally-tuned for the twisty bits and the straightaways.
- Build: Aluminium panels make it light, agile, and just a little smug.
If you’ve ever wanted to feel alive at 4,000 RPM, the GR Yaris is here to rewrite your idea of fun. It’s not just driving—it’s rebellion.
GR Corolla and GR Yaris Compatibility: Shared Parts, Unique Potential
The GR Corolla and GR Yaris are like siblings—cut from the same cloth but with their own quirks. Many parts, like suspension components and engine upgrades, swap between them as easily as childhood toys. Aftermarket makers love this shared DNA, crafting mods that fit both, from performance shifters to sleek induction kits.
Of course, not every piece is interchangeable—some quirks are unique. Fortunately, the garage function on our website takes away any confusion, allowing you to add your particular vehicle to filter it down to the compatible parts.
