GR Corolla AWD ITCC Cooler Motorsports Development

23/05/2026

Massive props to Chris Schuster and Lauren Judy from the team for securing a phenomenal 2nd Place finish last week in the Economy Class at the 2026 Tire Rack One Lap of America! 🏁

Their GR Corolla conquered a grueling 7-day, 3,500-mile marathon of endless highway transit, skid pads, and intense track sessions across middle America. When managing critical AWD temperatures mattered most under pressure, they relied on our 555 Transfer Case Cooler Kit. ❄️🏎️

555 Engineering Track Proven at Suzuka! 🇯🇵 🏎️

We recently had the privilege of track testing our full GRC Cooling Package at Japan’s F1 track, Suzuka Circuit. Coming to Japan has been a surreal experience for the 555 Engineering team. It’s one thing to build a kit; it’s another thing entirely to see it performing on a world-class F1 circuit like Suzuka.

We came to prove ourselves. 30-minute sessions at full tilt on one of the world’s most demanding tracks, and the Package didn’t miss a beat 🆒 👌🏼 .

But the best part? The Japanese GR Corolla Community. Hanging out with the local community and experiencing the passion and sense of family was absolutely the highlight of our trip.

We were humbled by the hospitality of our hosts and everyone else we had the privilege of meeting. We cannot thank you enough for having us 🙇.

PRODUCT ANNOUNCEMENT 📣 📣 📣 🚗

THE PITCH MOUNT PITCH MOUNT: REDEFINING THE LAWS OF RIGIDITY (AND SENSE)

After exhaustive data collection on an old chalkboard, we are proud to announce a product so revolutionary the aftermarket will never be the same again: The Pitch Mount Pitch Mount (PMPM).

We started by asking a simple question: “If a pitch mount is rigid, what if we mounted it to another pitch mount?” The answer, as you can see, is a product so redundant, so specific to the G16E-GTS, and intended for a segment so saturated we are not sure if it even makes sense.

✅ Nested Rigidity Matrix: Multiple layers of unobtanium and high-durometer unicorn tears to ensure that your engine does not move. Ever.

✅ Tri-Level Redundancy: A failure in one mount will be seamlessly ignored by the next nested mount.

✅ GR-Specific (and GR-Confused) Design: Tuned for the G16E-GTS to provide absolute drivetrain locking for performance that can only be measured in social media clout.

Grab yours while supplies last! We might have to take them down once we remember this is all just a joke. Or is it?
