The buzz is still wearing off the Detroit Auto Show but Japanese automakers are already at it again, this time at the 2010 Tokyo Auto Salon taking place in Japan this week. Similar to Las Vegas' annual SEMA event, the Tokyo Auto Salon is a hotbed for aftermarket and performance tuners showing off their wares, and more often than not the major automakers like to get in on the action as well.

Just days ago we showed you the FT-86 G-Sports Concept from Toyota and now we have the IS F Circuit Club Sports (CSS) concept vehicle from the upmarket Lexus brand.

The Circuit Club Sports is essentially a stripped out version of the regular V-8 powered IS F sports sedan, with lighter carbon-fiber replacing many of the steel panels from the production model. Things like the hood, trunk, front winglets, side skirts and rear diffuser are all made from carbon-fiber and more of the lightweight material is splashed around the interior as well.
Lexus hasn't messed around too much with the powertrain, choosing only to add a new exhaust system to raise the IS F's 5.0-liter V-8 engine output to 428 horsepower.
