Big Wang Splitter
The Big Wang + Splitter, as tested by Dr. Volks, is an innovative aerodynamic system that combines a large roof-mounted wing and an integrated splitter to maximize downforce and improve vehicle stability at high speeds.The unique set up helps to achieve the optimal flow around the car for maximum performance.This configuration creates a balanced aerodynamic profile, adding downforce and increasing grip, especially in high-speed corners. The system also features adjustable components, such as end plates and gurney flaps, allowing for precise tuning to suit different tracks and conditions. Designed for super-modified race cars, this setup is ideal for drivers looking to push the boundaries of performance while maintaining control and stability on the track.
The aero development work was carried out by DXM Engineering You can find more information about the HERE!

Findings Big Wang + Splitter VS Rear wing + Splitter
Big Wang Splitter (Roof-Mounted Aerodynamic System)
At 70 MPH, the Big Wang Splitter package generates 558.7 lbs of total downforce in the high downforce mode, with its roof-mounted wing contributing 761 lbs and the integrated splitter adding 195.93 lbs, while the car’s body creates 398.14lbs of lift. This system achieves a 63-60% front-downforce bias, creating a balanced aerodynamic profile that enhances high-speed cornering stability. The wing’s angle of attack can be adjusted on-the-fly on the straights, thus reducing the overall drag by 33%.The splitter’s placement interacts with cleaner airflow, reducing turbulence and preventing stall conditions common in traditional front splitters.

Rear Wing + Splitter Configuration
The simpler rear wing and splitter setup produces 223 lbs of total downforce at 70 MPH, with the wing contributing only 100.4 lbs and the splitter matching the Big Wang’s 195.9 lbs. With a 60-57% front-downforce bias, this package struggles to balance aerodynamic load, leading to understeer in high-speed corners as rear grip dominates. While drag is significantly lower (23.74 HP for total vehicle), the reduced downforce limits cornering speeds and stability. The car’s inherent lift is minimal (73.3 lbs), but this comes at the cost of compromised high-speed control. This configuration favors straight-line efficiency, making it suitable for tracks with long straights but less effective in twisty sections where mechanical grip and aero balance are critical.
