Dodge Challenger R/T

Built by MRX for the Ross Brothers of Cambridge, NZ.

Spanning almost 24months of construction and nearly 2000-man hours to turn this stock Challenger shell into the weapon before you.

This piece of racing art is truly the biggest feather in the MRX cap.

    The brief

    Take a stock Dodge Challenger shell and build something, not only fast enough to compete with the big boys of muscle car racing in NZ, but to sit pride of place in the Ross Bros Museum. The plan was in place, the car was dubbed... 'Kowalski'.

    The chassis

    The very first reproduction shell from Dynacorn USA, this was the perfect base for a race car build, no rust, no damaged metal. A beautiful blank canvas.

    With a build of this scale, the end product needs to be the vison from day one. Not only thinking one or two steps ahead, but ten or twenty.

    The shell was modified to take the custom 3 link rear suspension set up with adjustable watts link. The new shock mounts were fabricated and fitted to house the Penske 8750 shocks. The multi point chromoly roll cage was tig welded in for maximum chassis rigidity and protection.

    Once the chassis was detailed, the complete shell was then powder coated in Arctic White.

    The engine and running gear

    Powered by a 850+hp Gillet Evanham 358cu Nascar v8 engine, breathing through a custom set of MRX steeped 4 into 1 headers, 3.5" oval y pipe and custom MRX muffler.

    Engine is backed by a Holinger 5 speed dog box, using a 7.25" triple plate clutch. Drive is transferred through the 2 piece chromoly drive shaft to the Strange alloy diff head and steel spool which is housed in the MRX fabricated 9" diff housing. Full floating drive hubs and cambered spindles are using along with Winters solid axles.

    In charge of pulling the car up are Endless 330mm brake rotors being clamped by AP Racing 6 piston calipers and Endless 25mm pads up front, with 300mm rotors and 4 piston calipers out back.

    The exterior / interior

    With the car being themed around the hero car from the movie 'Vanishing Point', the car was always going to done in the fresh gloss white colour. Along with the Dodge RT accents, built with the 1970's TransAm in mind, the alloy front chin spoiler and rear boot spoiler were hand fabricated in house. The bonnet also needed some attention for clearance to the engine air intake. With didn't was to run the same old cowl scoop you see a lot, so we decided to keep with the Dodge RT bonnet bulge but sectioned the OE bulge and raised it 50mm.

    To complement the white body, a set of white lipped Forgeline GA3R 17x11" rims have been fitted.

    Carrying on the white and polish theme, custom white Racetech setas were produced for the car. Hand fabricated dash inserts and consoles were also constructed in house. And what Dodge is complete without a pistol grip shifter, again hand formed in house.
