With the SEMA Show officially starting tomorrow, we were in town early and thought we drop by to see what we might stumble upon. It was hard to miss the tasty Skittles rainbow of convertible Challengers parked out front. Dodge tuner Mr. Norm’s Garage was displaying five of the drop-top Challengers in different colors and with plenty of different custom work.

Mr. Norm’s has already released several Challenger performance packages including a Super Cuda, Super Challenger and the Legend’s Edition cars that come with rebuilt HEMI engines with forged internals and a Kenne Bell twin screw supercharger that pumps out 900-hp!

It doesn’t get much more extreme than this in the tire business. Known for building ridiculous one-off tires for the SEMA Show, in the past Italian tire manufacturer Pirelli has shown such monstrosities as a 30-inch tire – on a Hummer no less. For the 2009 SEMA Show, the company has decided to go in the opposite direction.

No… we’re not talking about smaller tires, but wider ones. Debuting on a brand new 2010 Camaro are a set of Pirelli tires in a 405/25/24 fitment. The wheels were supplied by bling wheel maker Forgiato and with some custom flared fenders that will have Bumblebee doing a double-take. An AirRunner air bag suspension lets the Camaro drop low for the show, or raise up for more functional use. Still, we doubt this Camaro will even see Main Street, let alone the drag strip.

Dodge has officially unveiled its 2010 Challenger NASCAR racer (at least from one angle) with an announcement that it will field a two car team in next year’s Nationwide Series, run by Penske Racing.

“As the performance brand of our new company, we are excited to expand our relationship with Penske Racing and introduce the iconic Dodge Challenger as our entry into the NASCAR Nationwide Series,” said Dodge Car Brand CEO Ralph Gilles. “Motorsports are a significant part of the Dodge brand’s legacy. Penske Racing has such a rich tradition in motorsports, and our partnership in the Nationwide Series will provide an excellent opportunity to showcase the Challenger and offer our loyal Dodge enthusiasts plenty of excitement in this very competitive series next year.”

Along with the two car effort, Dodge has also committed to supporting Penske’s three teams in the NASCAR Sprint Cup Series.

Initially the two Nationwide Series cars will be Chargers, with the Challenger stepping in for four races, starting with Daytona in July. Justin Allgaier will drive the No. 12 Verizon Wireless car, with Brad Keselowski in the No. 22 Discount Tire car.

Dodge expects to make the move the the Challenger for the full season by 2011.
