Last February Lexus took the wraps off its IS350C F-Sport package (pictured), dressing up the hardtop convertible with a dose of sporty attitude. Today, the Lexus announced a new Special Edition version of the car that offers more performance and style.

Only 100 2010 Lexus IS350C F-Sport Special Editions will be produced, starting from $58,375, a premium of about $13,000 over the standard IS350C, and right around the same price as the standard IS350C F-Sport. The Special Edition gets the standard F-Sport treatment and kicks it up with upgraded brakes at all four corners for "firmer pedal feel and enhanced fade resistance," plus Bilstein shocks, lower springs, a stiffer anti-roll bar set, new 19-inch alloy wheels, a unique grille, embroidered floor mats, leather shift knob, a serial-numbered console plate, and unique exterior badging.

Other unique elements for the Special Edition include black-trimmed leather seats with blue contrast stitching, a choice of two exterior colors (Tungsten Pearl or Obsidian black), plus heated front seats, standard bi-xenon HID headlights, and Lexus Navigation with Enform, XM traffic and weather.

The 2010 Lexus IS350C is powered by a  306-horsepower 3.5-liter V-6, with 5.8-second 0-60 mph and 14.1-second quarter-mile times.

The Special Edition will be available at the end of the month.
