The American Club Racing (ACR) model was introduced in 1999, starting with the Viper GTS (Phase SR II). This model had suspension and engine enhancements focused on maximizing performance in road racing and autocross environments. Horsepower was bumped to 460 hp (370 kW) in these models, while torque increased to 500 lb·ft (678 N·m). Weight was reduced by over 50 pounds (23 kg) by stripping the interior and removing other non-essential items such as the fog lamps (replacing them with brake ducts). The new stiffer, adjustable suspension removed another 14 pounds (6.4 kg) These models, which also have engine and handling modifications, has an "ACR" badge and 20-spoke BBS wheels.
In an attempt to stay true to its heritage, I've left this beast without bells and whistles in the name of speed. It sport a front clam shell hood, opening rear trunk, and spring back doors. The cool thing is the speed and motor options.
Never done before in a 1:8 supercar, this Viper packs 2x Buwizz 2.0 (with Ludicrous mode) that power this monster with 2x Buggy motors. The gearing is accessible and can be swapped for a higher or lower gear in minutes. Ratios avail: 1:1 and 1:1.6. This model also has many build options:
1. 1 or 2 buwizz / 1 or 2 Lipo / 1 or 2 Sbrick 2. 2 Buggy motor or 2 XL motor for drive 3. Fully manual car (just remove the electronics)
