According to a Jalopnik Q and A with Mark Stielow, the 2014 Chevrolet Camaro Z/28’s chief engineer of chassis dynamics, the team at one point gave the 2014 Camaro ZL1 some of the cornering hardware that makes the Z/28 the fastest track attack production Camaro that’s ever graced the earth. This means that there was a ZL1 rumbling around Road Atlanta with Pirelli Trofeo R tires that were 305-wide in all four corners. And thanks to the 75 hp advantage the ZL1’s LSA has over the Z/28’s LS7 V8, the unique Camaro mule seemed ready to dominate the Z/28.
But it still wasn’t faster.
Stielow explained why the super ZL1 was still slower than the less-powerful Z/28, stating that “you need to rebalance the chassis to take advantage of the tires.”
So for all you ZL1 owners out there getting ideas… you might want to look beyond a tire swap.
