The 1LE uses the same 650-hp, 650-lb-ft supercharged 6.2-liter LT4 V-8 as the standard ZL1, so all of the upgrades happen outside of the engine bay. The 1LE replaces the stock 285-width tires with 305s in the front and 325s in the rear. The tires are Goodyear’s new Eagle F1 Supercar 3R, the company’s first cup tire design. | The tires were developed specifically for the ZL1 1LE and are the widest ever to appear on a factory Camaro. |
