2014 Chevrolet Camaro Z/28 By the Numbers
More specs and data released to make Camaro lovers drool

Following the stunning announcement of the 2014 Chevrolet Camaro Z/28’s impressive Nürburgring times, despite the weather conditions, GM also launched a full array of fascinated facts about its ultimate track performer. Quite simply, the Z/28 was built specifically to be faster than anything Ford can deliver. Not only was the Z/28 faster on the Nürburgring than the ZL1, but during development the Z (1:53.71) also surpassed it (1:56.58) on the Milford course as it did the 1LE (1:58.85), the 2012 Mustang Boss 302 Laguna Seca (1:59.05), and the 2013 GT500 (1:59.97). And just how did they build such a fast car?
• 190 unique parts from the 2014 Camaro SS to the Z/28
• 3,837-pound curbweight
• 7.59 pounds per horsepower
• 1.5g in deceleration
• 305/30ZR19 Pirelli Trofeo R tires, largest front tire on any production car
• 1.08g lateral acceleration
• 33mm lower center of gravity than the Camaro SS
• 63.7-lbs lighter by choosing the LS7 over the LSA
• 505hp at 6100rpm
• 481 lb-ft of torque at 4800rpm
• 2.66/1.78/1.30/1.00/.74/.50-ratio TR6060 manual transmission
• 3.91:1 final drive ratio
• .7-seconds per lap faster with the Torsen helical limited slip differential
• 394x36mm front, 390x32mm rear brake rotors
• 20x lifespan in the rotors as the pads
• 6-piston asymmetric front, 4-piston rear monobloc, fixed calipers
• 19x11 front, 19x11.5 rear wheels (weight, center of gravity, rear tire handling at the limit)
• 440 pounds more downforce at 150mph than the SS
• 85% stiffer front springs, 65% rear springs match DSSV dampers
• 25% stiffer lower trailing link bushings (lateral stiffness and deflection)
• 50% stiffer front lower arm link bushings (steering feel)
• 400% stiffer rear upper control arm bushings (lateral stiffness)
• 25mm front, 26mm rear stabilizer bars (smaller than SS)
• 40mm piston, 45mm OD tube in front struts
• 45mm piston, 2.6lbs weight savings with aluminum body on rear damper
However, the whole is definitely greater than the sum of its parts when it comes to the Z/28. In addition to the first dry sump lubrication system in a Camaro, the Z also uses engine oil, transmission, and differential coolers to make it track capable. These parts are unique to the Z/28, but bear striking resemblance to the Corvette ZR1 (engine oil cooler) and ZL (diff cooler). The trans is another leap forward from the base Camaro, boasting closer ratios and beefier components– double- and triple-cone synchronizers on all gears with a matching number of friction surfaces. The Torsen helical geared diff is another leap forward, which improves corner entry, exit, and mid-corner traction by allowing the ABS to function independently on each wheel, rapid torque coupling, and zero preload means no resistance for better steering and speed. Though the carbon rotors are a big focal point, the asymmetrical piston design on the brake calipers distributes the clamping force more evenly and increases the pad surface area for longer pad life. And last, but definitely not least, a great deal of time was spent selecting and tuning the DSSV Multimatic struts and dampers, which have its roots in Champ Car, Formula One, and many other highfalutin professional race series. To put it mildly, the Z/28 has the best parts money can buy and is one impressive machine.
