The drive shaft on the modern GTO is a known weak link, and when any modifications are made to the power output, it is a good idea to upgrade it. The last time we checked in with this particular GTO, you'll remember we released some extra power from the 6 liter V8 by opening up the exhaust system. The suspension was already tweaked with some better bushings all around, so we tackled the driveline here.
In 1964 Pontiac engineers stuffed a 389 cid engine in a Tempest, called it the GTO option, and created arguably the first mid-sized muscle car. Almost fifty years later, GM tapped their Holden enterprise in Australia-- where muscle cars still thrive-- and created the modern GTO. Equipped with GM's venerable small block V8 engine, the current GTO is based on the Holden Monaro. A disappointment to many GTO loyalists, thanks mostly to its bland styling, the modern GTO is nonetheless a good enough performer. But good enough is the enemy of better at VRPerformance, where we feel that almost every car can be improved with the right equipment and service.
