The GR Corolla uses Toyota's turbocharged G16E-GTS 1.6 liter three-cylinder, rated at 300 horsepower and 295 lb-ft of torque for 2025 and 2026. On a turbocharged engine, the core power parts are the downpipe, the intake and the tune, because together they change exhaust flow, airflow, boost and fueling. For that core, we offer the LIMIT+1 GR Corolla High Flow Downpipe + Midpipe w/ EPA Approved GESI Cat, intakes such as the Eventuri GR Corolla Carbon Intake System, and EcuTek custom tuning through LIMIT+1 x Boosted Performance Tuning.

We also offer LIMIT+1 GR Corolla Power Packages 1, 2 and 3, with details on each product page. Beyond power, our GR Corolla list covers intercoolers, oil coolers, catback exhausts, lowering springs, coilovers, pitch stop mounts, brake pads and rotors.

Alongside our own LIMIT+1 parts and genuine OEM Toyota parts, we carry GR Corolla parts from Eventuri, AWE, HKS, Borla, REMARK, Invidia, CSF, Mishimoto, PWR, Jackson Racing, GiroDisc, Endless, Project Mu, Pagid Racing, EBC, XClutch, Clutch Masters, ACT, H&R, Eibach, Motion Control Suspension, Fortune Auto, Whiteline, SPL, Verus Engineering, Seibon, Rally Armor, SXTH Element, Artec, DC Sports and Red Line, among others.

That covers GR Corolla catback exhausts, carbon intakes, turbo inlets, intercoolers, oil coolers, big brake kits, two piece rotors, brake pads, coilovers, lowering springs, clutch kits, camber arms, aero, wheel spacers and mud flaps. Our own line includes the LIMIT+1 GR Corolla High Flow Downpipe + Midpipe w/ EPA Approved GESI Cat, the LIMIT+1 GR Corolla Oil Cooler Kit, the LIMIT+1 x Delicious Tuning GR Corolla Flex Fuel Kit and EcuTek custom tuning through LIMIT+1 x Boosted Performance Tuning.

Whether a GR Corolla part requires a tune is listed on its product page, and the factory calibration is written for factory hardware. A custom tune is what matches boost and fueling to your parts, and we tune the GR Corolla with EcuTek through LIMIT+1 x Boosted Performance Tuning, either as a phone flash custom tune or an in-person custom dyno tune.

Toyota rates the 2025 and 2026 GR Corolla at 300 horsepower and 295 lb-ft of torque, and 2023 and 2024 Core, Premium and Circuit Edition models at 300 horsepower and 273 lb-ft. How much a tune adds depends on your fuel and supporting parts, so contact us for results on a setup like yours. On warranty, the Magnuson-Moss Warranty Act means a dealer cannot void an entire factory warranty simply because aftermarket parts are installed, but a specific claim can be denied if a modification is determined to have caused the failure, and ECU changes are detectable. Warranty decisions are made by Toyota and its dealers, not by LIMIT+1.

Everything in this collection is listed for the GR Corolla, which Toyota introduced for the 2023 model year on its GA-C platform with the G16E-GTS turbocharged three-cylinder. Grades over the years have included Core, Premium, Premium Plus, Circuit Edition and the 2023 Morizo Edition.

Some parts are specific to transmission, trim or model year. The 8-speed GAZOO Racing Direct Automatic Transmission became available for 2025, so items such as the SXTH Element GR Corolla Intercooler Kit (MT ONLY) and our manual and automatic fluids are listed by transmission, and the 2023 Morizo Edition is a two-seater with its own close ratio manual gearing. HKS front lips are also listed separately for 2023 to 2024 and 2025 and newer cars. Check the fitment notes on each product page, or contact us before ordering.
