Magazine Excerpt:"Both of these Corvettes [ZR-1 and Callaway] are outstanding performers. They're also about the same price. So buyers are left with a decision of which powerplant philosophy they prefer. In my opinion, you can't go wrong either way. The ZR-1 has the new Euro-think aluminum engine, while the Callaway is perhaps the ultimate expression of the American hot-rod ethic. The factory gets the job done with revs, the skunk-works machine does it with sheer torque.
While I'd love to own either of these supercars, my personal preferece is for the Callaway. Now I like a high revving exotic as much as the next guy, but let's face it, torque makes most of the magic things happen. And the Callaway is the torque-master in this contest. The Twin Turbo solution is neat, high tech, unusual, and well executed. While the factory will crank out two to three thousand ZR-1s this year, Callaway will build but 250 Twin Turbos. that exclusivity means something, too. My choice: support your local hot rodder -- buy a Callaway! - P.A."

C'est pas pour la planche de bord quand même ?

et là aussi c'est de 375 : http://www.supercars.net/cars/374.html

mais effectivement, sur corvette action center c'est 4 * Goodyear Eagle, P275/40ZR17 et c'est sûrement bien plus fiable sur ce site
