SEMA '09: Mopar Jeep Wrangler Lower Forty "BigFoot" with Massive 40-inch Tires and HEMI V8

Taking the latest generation Jeep Wrangler to a new extreme, Mopar has designed the uber-impressive "Lower Forty" concept for this year's SEMA Show in Las Vegas. The crazy Wrangler Lower Forty rides on massive 40 x 13.5-inch tires mounted on Mopar's 20-inch forged-aluminum wheels while power comes from a 5.7-liter HEMI V8 engine coupled to a Getrag 238 six-speed manual gearbox. The Mopar-supplied Dana 44 front axle and a Dana 60 rear axle, fitted with 5.38 gears and ARB air lockers complete the mechanical upgrades.

In order to fit the massive wheels on the Wrangler Rubicon without using a suspension air lift, Mopar's team created custom front and rear fender flares that are 1-inch wider and are located 4 inches higher than on the stock model.

Other exterior modifications include the chopped windshield frame that gets a 10-degree rake, a one-piece carbon-fiber hood with a Jeep CJ-like power dome and an all-new drop-down tailgate stamped with the "Jeep" logo.

The Lower Forty also gets a roll cage that is tied directly into the frame rails, a color-matched center console and instrument panel and two-tone Katzkin leather seats while the carpet has been replaced with spray-in truck-bed liner.

Viper Competition Coupe
As of 2003, a special, non-street legal Viper SRT-10 Competition Coupe is available from Dodge for race car drivers, picking up where the GTS-R racing variant left off. The power and torque ratings have been improved, but the vehicle has been stripped of anything not essential for racing, such as the interior body panels, instrumentation, air conditioning, and stereo system which lightened the car by 380 lb (170 kg). The "CompCoupe" comes equipped with a full roll cage, a racing fuel cell, and other racing-related equipment. It is not sold through dealers and is purchased from Dodge directly as, essentially, a very expensive race car component. Pricing is approximately US$139,000. The Viper Competition Coupe sees action in the highly competitive SCCA Speed GT World Challenge.

In 2004 Samuel Hubinette used a Competition Coupe with a modified rear axle for the Formula D, in which he won the title before the car was barred by the end of the season (due to the fact FD would adopt D1 Grand Prix regulations from the following year which had already prohibited the car from competing) and was replaced by an SRT-10 the following season.

After a few one-off entries in the Spa 24 Hours, from 2006, the Viper Competition Coupe will race in Europe fulltime for the first time, joining the new FIA GT3 Cup with the Italian team Racing Box.
