The Motec GR86 and BRZ M142 Plug and Play ECU Kit is NOW AVAILABLE!

For track focused builds, this kit fully replaces the factory ECU on 2022 and newer GR86 and BRZ models, using the existing wiring, fuel system, and sensors. It keeps push button start, cruise control, air conditioning, and all dash functionality, while adding launch control, traction control, and programmable driver switches. The included start file is calibrated to factory fueling, ignition, and camshaft phasing, so setup starts from a working baseline.

The SXTH Element GR Corolla CPLT Intake and Turbo Inlet have been DISCONTINUED. FINAL UNITS ARE IN STOCK AND READY TO SHIP!

Both have been among the most popular GR Corolla parts we carry over the last few years, and what we have on the shelf now is the last of it. There will be no restock once these are gone. The Turbo Inlet is designed to pair with the SXTH Element intake, so if you are running the CPLT Intake or planning to, this is the last chance to complete the setup.

ACT clutch kits for the GR Corolla are NOW AVAILABLE FOR PURCHASE!

Four options covering everything from daily driven to full race use, expected to ship within the next month. The HDSD and HDSS share ACT's Heavy Duty pressure plate and 407 ft-lb capacity, 20 percent over stock, with the HDSD's rigid hub disc built for the fastest shift action and the HDSS keeping a sprung hub for smoother, quieter engagement. Stepping up, the HDG6 pairs that same pressure plate with a 6 pad ceramic race disc rated to 619 ft-lb, an 82 percent jump over OE, built for high horsepower street or race use. The XACT Streetlite flywheel rounds out the lineup at 15.5 lbs in chromoly steel, cutting rotational mass without giving up durability.

This build was about one thing: making a GR Corolla that can hold its own on track without losing what makes it good on the street.

Working alongside our sister company .automotive, we dialed in the platform with Annex FastRoad Pro coilovers and SPL rear upper camber arms, giving us the range to properly balance the chassis front to rear. Apex VS-5RS forged wheels and ARP extended studs took weight off the corners, while GiroDisc rotors, Endless MX72+ pads, Spiegler stainless lines, and Motul RBF 600 make sure the brakes feel the same on lap twenty as they did on lap one.

Our new Lexus GX 550 shop car got some special treatment with a Westcott Designs lift and Method Race Wheels 703 setup.

We recently picked up this Lexus GX 550 for both R&D and to begin developing our tuning for the platform, but before that could happen, we had to make it look the part. This setup includes the Westcott Designs Preload Collar Lift Kit in Luxury spec with a black anodized finish, paired with Method Race Wheels 703 Bead Grip. The Westcott kit uses your factory shocks and springs to deliver 2.50" of front lift and 0.75" in the rear while retaining factory ride quality and suspension geometry, requires no upper control arms, and clears up to a 35" tire. Method's patented Bead Grip technology engages the tire bead to hold air pressures that previously called for a true beadlock, letting you air down for a larger contact patch without risking a debead on the trail.
