A BMW F80 M3 or F82/F83 M4 CS-style carbon-fiber front lip and the black ECPR lower splitter are two separate parts. The carbon-fiber lip creates the CS-inspired shape; the lower splitter mounts beneath it to add visual depth and help protect the lip's most exposed edge.
The most important fitment rule is simple: the ECPR lower splitter requires an OEM BMW CS lip or a compatible aftermarket CS-style carbon-fiber lip. It does not mount directly to the factory bumper.
What parts do you need?
The complete front-lip stack is:
- The factory BMW F8x front bumper
- An OEM BMW CS lip or compatible aftermarket CS-style carbon-fiber lip
- The ECPR lower splitter mounted beneath the carbon-fiber lip
If your car does not already have a compatible lip, start with the BMW F8X M3/M4 CS-style carbon-fiber front lip. Then add the ECPR lower splitter for the CS-style lip.
OEM lip: choose the pre-drilled splitter
For an OEM BMW CS carbon-fiber lip, choose the lower-splitter option with pre-drilled holes. The hole locations are prepared for the OEM lip, and installation hardware is included with this version.
Aftermarket lip: choose the non-drilled splitter
Aftermarket CS-style lips can vary slightly in shape and hole placement. Choose the non-drilled lower splitter so it can be test-fitted and the final mounting points can be confirmed against your specific lip before drilling.
What the lower splitter adds
- Strong, durable black textured plastic made in the USA
- Laser-guided cutting for consistent fit and finish
- Extra visual depth beneath the carbon-fiber lip
- Protection against scratches and damage along the lip's lowest edge
The lower splitter is designed for street-driven cars and OEM+ builds where protecting an expensive carbon-fiber component matters as much as the added styling.
Installation expectations
The pre-drilled version mounts with supplied self-tapping stainless-steel screws and double-sided tape. The lower splitter can be installed by an experienced DIY owner or a professional shop, but the carbon-fiber lip should be test-fitted and aligned before final fastener placement.
For an aftermarket lip, use the non-drilled version and confirm every mounting point during test fitting. Professional installation is available by appointment at the EuroCustomsPR shop in Rockledge, Florida.
