Usually, when an automotive conversion is taking place, it’s a road car getting tuned up for the track. But every once in a while, there’s a racer that’s so badass, tuning firms have to make it street legal. This is the case with the Dodge Zakspeed-Viper GTS-R by Heurich Classics. Dodge may be working on their new generation Viper , but for many, the second generation is the true calling for the sports car and the 1998 Viper GTS-R was just too good to be left alone.
The 1998 Viper originally belonged to Zakspeed Racing, but was purchased in 2010 by someone who wanted to recreate the Viper in the original design present during the vehicle’s win at the 1999 legendary 24 h at the Nürburgring, and make it street legal. For this, they turned to Heurich Classics, a Germany tuning firm that specializes in maintaining and repairing vintage classics.
Many changes had to take place in order for this classic racer to be turned into a street legal mad machine. The Viper had to get its spoiler cut, its rear diffuser removed, and its side channels rebuilt, as well as its brake system changed. New tires and wheels were special ordered and a new hand brake system with CNC-machined caliper carriers was installed. For the interior, the seats, harness, and glazing were renewed, and new passenger seats were installed. All of the electrical work was also redone. The finishing touch was provided with the traditional colors and livery of the original Hasseroder Viper GTS-R.
After completing the work on the exterior and interior, the tuner turned its focus on the engine. The steering angle had to be increased, the cooling system changed, additional fans installed, engine peripherals modified, and the exhaust system adapted to get the Viper up to code. As a result, the 6.2-liter V8 engine now delivers a total of 600 HP, combined with a Tremec six-speed manual gearbox.
