GT-R Festival sponsored by Maatouks Racing, done and dusted just like that. What an awesome event!
Despite the rain putting a damper on things, it was all smiles and good vibes. Great to see many familiar faces, and catch up with life long customers, friends, even some from high school.

We had our JEM stand, sold some merch, and got to shake hands with leaders of our industry, Andrew Hawkins, Anthony Maatouk, Herman from PRP, Michael and Roumanos and the KOTS crew, Scott from Haltech, Anthony WARGTR CRD, Kyle Hi Octane, Greg Autosport, Rod Markland and Terry Ashwood, Billz STRAPT and the B2R boys, Mack Racing, Frosty, Leigh-Anne, Grace and the Motiv DVD crew, MPW crew, CEO of Nismo, Maatouks crew, All Red Everything crew, IHRA crew, Connor SIK100, to name a few, plus more, you guys all rock, thank you for your help and hospitality.

A huge thanks to the JEM crew, Jimmy, Jordan, my family and friends, without you this weekend couldn't have happened.

Thank you to our friends and customers for your support, and joining us on our stand, displaying your cool cars, and hanging out.

Congratulations to everyone who pb'd, and made it to the event, see you all at the next one!

Congratulations to Jimmy for another pb in the Hilux running and 8.5@158mph and keeping the front wheels down this time!

Last but not least, JEM034 took home the trophy once again for highest HP RB30 3rd year in a row making 1580HP. Also took the trophy for top 10 Ultimate GTR so we're over the moon.

Thank you again.
❤️Adam and the JEM team.
