The 2014 Chevy Camaro Z/28 is looking like the most extreme track-oriented vehicle GM has ever 
announced, thanks to a bare-bones approach inside and out, coupled with 
some really incredible hardware, with no one feature being the main 
highlight, but rather complimentary to the rest. Sure, everyone 
recognizes the all-motor 7.0L LS7 V8 engine, which is arguably the best 
performance engine Chevrolet has ever offered. But there’s also the 
60-tread count Pirelli P Zero Trofeo R tires.
These marvels of rubber are street-legal slicks, essentially. And as a
 fun fact, they’re built in the same facility where Pirelli manufactures
 its Formula 1 racing tires. More impressively, the Trofeo R tires 
designated for the Camaro Z/28 measure 305/30ZR-19 in all four corners. 
Enormous. So big, in fact, that Chevy claims the size to be the largest 
front-mounted tire of any production car on the market.
For reference, the Bugatti Veyron sports 265-size tires in the 
front.The enhanced size of the contact patch, along with a 20-percent 
stiffer spring rate over the Camaro 1LE and purpose-built DSSV shocks 
unique to the Z/28, are said to give the LS7-powered road-course killer 
the cornering abilities of 1.05 G forces. That’s better than most 
supercars, and completely unheard of for what many relate to as a muscle
 car.
