The GT4 Splitter is Ridgeline Motorsport's front aero answer for the E46 M3. It sharpens the front end without fighting the shape of the car, which is the hard part on a chassis this well proportioned. The profile sits lower and further forward than stock, and the extended surface pushes air toward the radiator and brake ducts instead of letting it spill under the car. You get better cooling and real front downforce out of the same piece.
Construction is 2x2 carbon fiber, light and strong enough for a car that sees track time. The splitter ships undrilled, which is deliberate. Every E46 sits a little differently by the time it has aftermarket suspension, a replaced bumper, or a set of tow hooks, so you set your own mounting points and mount it exactly where your car needs it. Hardware is not included. Made in Taiwan.

Installation
The splitter arrives undrilled and without hardware, so plan on sourcing your own mounting hardware and support rods if you are running it hard. Professional installation is recommended.
Test fit and mark your mounting points before drilling anything. Placement depends on your bumper, ride height, and whether the car is running an aftermarket front end.
Motorsport Product Disclaimer
Aerodynamic results vary with ride height, speed, suspension setup, and the bodywork around the splitter. Track use puts significant load on a front splitter and its mounting points. Confirming the mounting is adequate for the intended use is the installer's responsibility.
