⦿ PRE-ORDER (BATCH 2 - EST. SHIPPING 1/31/25)

Looking to add additional front grip, corner faster, and brake shorter? The Racebred Components Universal Splitter Diffuser Tunnels were designed to help increase front downforce on a standard flat splitter.

Using 3D modeling and CFD analysis, we adopted a proven methodology of a dimpled surface; reminiscent of a golf ball, to help glide air across the diffuser tunnel surface, increasing the low-pressure zone further forward, resulting in improved downforce and decreased drag.

Our Dimpled Splitter Diffuser Tunnels are built to last – just like our splitters. Manufactured from injection molded polyurethane, these tunnels are designed for long term abuse and will not crack or shatter like ABS plastic or fiberglass and will continue to perform in the harshest race environments. 

WHY THE DIMPLES?

Simply put, adding dimples moves the low-pressure zone forward and encourages the air to have an increased attachment versus a smooth surface, which results in increased downforce. Placing dimples on a surface will increase the friction drag but will reduce the pressure drag by having the turbulent boundary layer attached further before separation.

DISCLAIMER: Splitter Diffuser Tunnels will exponentially increase downforce. Additional chassis mounting and splitter reinforcement is required. *CFD analysis was simulated using a ready-state scenario. Numerical figures shown are results from in-house parameters and may differ from other models due to a number of variances involved. These simulations were used to gather and optimize overall vehicle performance, which were then track tested and validated with driver data and results.
