Carefully Engineered. Built to Last.
Kartboy first gained recognition among Subaru enthusiasts in 1999 for its innovative product design and precision manufacturing. Quality endures.
“Yes, it’s true, Kartboy rocks. I just installed my STi short shifter and it feels great. There is a huge reduction in throw. The parts were top‑notch quality… Quick and easy install with the right tools… way to go Kartboy!”
— Ari Allen on NASIOC
“It’s a great upgrade, and probably the most bang for your buck performance wise for a hundred bucks… The throw is SIGNIFICANTLY shorter… much better over stock… Overall, best $138 mod you can do for your car.”
— evohuntinwrx on NASIOC
“I’ve had Kartboys on all 3 of the Subarus that I have owned, wouldn’t trade them for anything…”“…it turns your car into something completely different!”

WHAT'S NEW:
Subaru Saturday: Chris Loney's Right-Hand Drive Forester SF
Chris Loney's right-hand drive SF Forester started as a Winnipeg winter beater and turned into one of the most uniquely built examples in the community — blown engines, a Frankenstein drivetrain, and a runner-up finish in Battle of the Boxers along the way.
Feature Friday: The Forester That Won
What started as a need for a family hauler became one of the most methodically built Subaru Forester XTs in the community. Scott Wilson, Battle of the Boxers champion, sat down with us to talk 12 years of mods, a JDM drivetrain swap, a custom half-cage, and the philosophy that ties it all together: build for yourself.
