Claim to Fame: A C6.R for your daily driver
If what you want is a racing Corvette for the road, then it’s probably best to ring up Pratt & Miller -- the same folks who helped build and craft both the C5.R and C6.R race cars.
OK, Pratt & Miller’s C6RS isn’t quite a road-going C6.R, but it does manage to share a number of parts with its track-tuned sibling. Like the racer, the entire body -- which is 1.6 inches wider than a regular Z06 -- is crafted from carbon fiber. Pratt & Miller also performs a number of chassis modifications, including slamming the ride height by 1.5 inches, adding adaptive dampers, and upgrading the brake system.
When it first launched in 2008, the C6RS was available with a monstrous 8.2-liter V-8 custom-built by Katech Performance, but buyers looking for a power boost these days can spring for a package Pratt & Miller has dubbed the LS9-RS. This engine is a supercharged 7.0-liter LS7 V-8, fitted with LS9 heads, forged pistons, and a number of valvetrain upgrades designed to handle the power increase. The entire package, according to P&M, produces 760 horsepower and 820 pound-feet of torque.
One advantage this engine has over the old 8.2-liter V-8 is pricing -- ticking this option box adds only $32,000, as opposed to $39,000. Even so, the C6RS is a pricey proposition. The basic conversion itself, which adds the bodywork, suspension upgrades, and larger wheels, runs $98,695 on top of the cost of a donor C6 or Z06. Add the so-called Performance Package, which throws in the LS9-RS, sound deadening, full leather interior, performance seating, custom exhaust, center-lock wheels, Brembo brakes, and an upgraded radiator, and the conversion jumps to $178,500. Of course, combo deals aren’t for everyone, and Pratt & Miller does allow buyers to pick and choose what options they’d like added to the mix.
