2025 Toyota GR Corolla Performance Specs and Modding Potential

Under the hood, the 2025 GR Corolla sports a 1.6-liter turbocharged inline-3 engine that cranks out an impressive 300 horsepower and 273 lb-ft of torque. It’s paired with Toyota’s GR-Four all-wheel-drive system, giving you the traction you need to dominate tight corners and slippery roads. With three selectable drive modes—Normal, Sport, and Track—you can customize the power distribution to suit your driving style.

One of the biggest draws of the GR Corolla is its drivetrain options. Unlike previous iterations, the 2025 model comes with both manual and automatic transmission choices. The six-speed manual is a no-brainer for purists who crave that classic, hands-on experience, while the new 8-speed Gazoo Racing automatic option is perfect for those who want precise gear changes without the legwork - plus, you get paddle shifters. Regardless of your choice, Toyota has ensured both setups deliver impressive responsiveness and performance.

But here’s where it gets interesting: the modding potential on this platform is insane. The turbocharged engine is just begging for a bigger turbo or upgraded intercooler, and the AWD system can handle more power than stock. Combine that with the relatively lightweight chassis, and you've got a recipe for a wicked fast build.

Engine and Drivetrain Upgrades For The 2025 Toyota GR Corolla

To make the most out of the GR Corolla’s performance, start by upgrading the intake system to improve airflow and boost throttle response. High-flow cold air intakes are a solid choice, as they’re built for power gains while maintaining reliability. Pair that with a cat-back exhaust for a more aggressive tone and reduced backpressure.

If you’re going all out, consider a turbo upgrade to push more boost and power through the system. 

Next up, swap out the factory intercooler for a front-mount option to keep charge temps low—especially if you're pushing more boost. Upgraded clutches and lightweight flywheels are also key to keeping your drivetrain reliable and responsive. Check out Competition Clutch or XClutch kits to handle the extra torque without breaking a sweat.

Common Weak Parts To Address On The New Toyota GR Corolla

Like any performance car, the GR Corolla has a few known weak points that enthusiasts should address, especially when increasing power. The two most common areas of concern are the valve springs and the clutch. Let’s break down why they’re problematic and how to upgrade them for reliable performance.

1. Valve Springs

 The factory valve springs can become a weak link when pushing higher boost or revving the engine harder. Many owners opt to upgrade to Kelford Performance Beehive Valve Springs, which offer greater stability and higher RPM capability. To maximize gains, some enthusiasts also upgrade to Kelford Stage 1 Cams at the same time.

Recommended Upgrades:

• Kelford Performance Beehive Valve Spring Base and Titanium Retainer Kit (2023 Toyota GR Corolla)

• Kelford Cams Camshaft Set Stage 1 (266/274) (2023 Toyota GR Corolla)

2. Clutch

With more power and torque, the factory clutch can start slipping—especially during hard launches or spirited driving. Upgrading to a performance clutch is crucial for holding power reliably. The XClutch Sprung Organic Kit is great for street builds, while the Ceramic Race Disc Kit handles more aggressive setups. For a balance of daily drivability and performance, consider the Clutch Masters FX100 or FX250 Single Disc Kits.

Recommended Upgrades:

• XClutch Clutch Kit - Sprung Organic (2021-2022 Toyota Yaris GR AWD 1.6L G16E-GTS)

• XClutch Clutch Kit - Ceramic Race Disc (2021-2022 Toyota Yaris GR AWD 1.6L G16E-GTS)

• Clutch Masters FX100 Single Disc Clutch Kit (2023 Toyota GR Corolla)

• Clutch Masters FX250 Single Disc Clutch Kit (2023 Toyota GR Corolla
