Viper Scale Racing V-3 Medium "B" Chassis w/ Level 10 High Downforce Magnets

One medium "B" chassis with V-3 guide pin, timing bracket, and magnet clip.  Chassis will accept parts from Viper Scale Racing and Harden Creek Slot Cars. Certain other parts such as axles, gears, hubs and tires from other manufactures can be used.  Molded in lexan body posts. 

Includes a set of Level 10 "Stepped" traction and High Downforce motor magnts. 

The “V-3” is the next evolution of our proven V1 platform—designed for racers who demand innovation, versatility, and raw performance. Still based on the race proven V1 geometry, the V-3 pushes performance further while retaining full compatibility with most V1 parts. Whether you're upgrading an old favorite or building a club-level rocket, the V-3 is your new go-to. Lighter. Stronger. Smarter. Faster.

Specs & Features:

• Ultra Lightweight design- Lower CG then the V1, Faster acceleration, cornering and more 
• Multiple Guide pin positions- 3 Positions including 1 behind the axle for those tight and twisty turns   
• Full Block type Traction mags- Ambidextrous design for High Downforce, Low downforce and Split Orientation
• Enhanced Rear Axle Support — Updated rear axle pin hole locators for ultra-precise pinning and bulletproof strength
• Revised Magnet Clip — Holds the middle of the magnets instead of the bottoms, Provides additional side clearance
• Ultralight Timing Bracket-  Windowed design is lightweight and stronger then V1 design

Rear axle pin hole locators- Allows easy pinning of rear axle.

Medium chassis great for any magnets intended for Ceramic Super Stock, Spec Racer, and CMPM.  

Chassis and traction magnets are HOPRA  approved. Motor magnets are waiting further HOPRA evaluations.

Complete car in photo example is not included.
