RENNtech’s rear diffuser specifically designed for the CLS 63 Biturbo is the companion component and perfect addition to our 3-piece carbon front splitter.
It visually enhances the rear of the CLS, acts as a functional component of the vehicles exterior in order to decrease drag and increases rear down force. This is accomplished by improving the underbody airflow and allowing for a smooth transition to ambient air when the vehicle is at speed.
As with the front splitter, their proprietary rear diffuser was designed and engineered in-house; is manufactured using the same high quality prepreg carbon fibre and is a quick and easy install that requires no modifications to the CLS’s rear bumper.
The centre section of the diffuser also accepts the EU third brake light or may also be removed and a mesh grill insert installed for an even more customized look. The rear diffuser also fits with the OEM exhaust tips
What exactly is prepreg carbon fibre
- Prepreg is widely known as the finest process in carbon fibre manufacturing and has been used for aerospace and military applications because of its superior consistency in weight, thickness, fitment, resin, carbon layout, and overall quality.
- Lower cost carbon fibre uses a wet-layup method which results in components of inferior, strength, appearance and overall quality. To create prepreg fibre is pre-impregnated (hence the name) with resin at a production facility, rolled on spools, and frozen to prevent the resin from curing prematurely. This material is then cut and hand laid into a mould to the proper thickness and cured at strictly controlled temperatures. This process creates a laminate with a precisely controlled resin volume and in turn is 20-30% stiffer and stronger than an equivalent thickness wet laminate process.
- The pre-impregnated (prepreg) fibre method creates stiffer, stronger laminates with controllable, predictable results and the result is a consistent, tight fibre weave which not only looks amazing, but adds strength. This ensures our customers receive components which not only look good on the vehicle standing still, but won’t crack, warp, fall off or fade when mounted to the exterior of their vehicle after six months or while driving at high speed.
