Build featured: Alex's BMW F80 M3
Written by: Ridgeline Motorsport Team
Quick Answer: Alex's BMW F80 M3 is a track-focused Time Attack build equipped with the complete Ridgeline Motorsport F8X GT4+ aero system, including the GT4+ Splitter Kit , GT4+ Canards and 1600 mm GT4+ Rear Wing . The build also features gold BBS E88 wheels, AP Racing Pro 5000R front brakes, an OEM BMW M4 GTS hood, an OMP Halo seat, a full roll cage and a JQ Werks GEN2 steering wheel system.
This BMW F80 M3 was developed around the demands of Time Attack driving. Its aerodynamic, braking and cockpit components were selected as parts of one integrated track setup rather than as isolated visual modifications.
BMW F80 M3 GT4+ Time Attack Setup
The objective of Alex's F80 M3 build is high-speed performance, predictable handling and a driver-focused track environment. The car combines a complete front-to-rear aero package with braking, wheel and safety upgrades selected for repeated track sessions.
The Ridgeline Motorsport GT4+ system establishes the aerodynamic foundation. A tunneled front splitter and four-piece canard set work at the front of the car, while a 1600 mm chassis-mounted rear wing completes the setup at the rear.
Gold BBS E88 motorsport wheels, AP Racing brakes and an OEM BMW M4 GTS hood support the chassis and thermal demands of the build. Inside, an OMP Halo seat, full roll cage and motorsport steering system create a more focused driver environment.
F8X GT4+ Front Splitter and Canards
The front aero configuration combines the Ridgeline Motorsport GT4+ Splitter Kit with the GT4+ Canards .
The splitter kit uses a two-piece design consisting of a carbon front lip/airdam and a separate tunneled lower splitter. Chassis-mounted brackets and center support rods provide the supporting structure for the assembly.
An integrated airflow channel gives air discharged from the factory lower oil cooler a defined exit path. Molded tunnels in the lower splitter manage airflow beneath the front of the car, while aluminum skid blocks protect exposed areas of the splitter during track use.
The four-piece canard set adds aerodynamic surfaces around the front bumper corners. Its vehicle-specific geometry complements the pressure field created by the GT4+ front lip and tunneled splitter.
Each component is available separately. Owners can install the splitter kit or canards individually, or combine both with the rear wing to create the complete GT4+ aero configuration shown on Alex's F80 M3.
1600 mm Chassis-Mounted F80 GT4 Wing
The rear aero component is the Rid1600 mm Ridgeline Motorsport GT4+ Rear Wing . Its wide mainplane gives the F80 M3 a substantial Time Attack profile and provides the rear aerodynamic element needed to complement the front splitter and canards.
The wing uses a chassis-mounted supporting structure. Aerodynamic load is transferred through reinforced uprights and mounting hardware instead of depending only on the outer trunk skin.
This is a Ridgeline Motorsport GT4-derived aero system for the F8X platform. It is not an OEM BMW M4 GT4 wing or factory BMW Motorsport body kit. The larger 1600 mm profile was developed for F80 M3 and F82 M4 track and Time Attack applications.
BBS E88 Wheels and AP Racing Brakes
The aerodynamic package is supported by chassis and braking hardware selected for repeated high-speed sessions.
Alex's F80 M3 uses gold BBS E88 motorsport wheels. The multi-piece E88 design is widely associated with BMW track and race builds, and its motorsport appearance works naturally with the proportions of the F80 chassis.
Behind the wheels is an AP Racing Pro 5000R front brake kit with CP9660 calipers and 372 mm discs. This setup is intended to provide the braking consistency and thermal capacity required during repeated track use.
An OEM BMW M4 GTS hood adds engine-bay ventilation while retaining a factory BMW M appearance. Together, the wheels, brakes and hood support the functional requirements of the complete F80 M3 track build.
Driver-Focused F80 M3 Interior
The interior follows the same track-focused direction. An OMP Halo racing seat provides additional lateral and upper body support for high-load driving.
A full roll cage forms part of the competition-focused driver environment and provides additional structural reinforcement. The cage, racing seat and controls create a cockpit suited to the car's primary track-use purpose.
Behind the MOMO MOD.88 steering wheel is the JQ Werks GEN2 Podium Line Steering Wheel System . It combines a quick-release steering interface with integrated controls for a more direct motorsport-style driver setup.

How the F80 M3 Track Components Work Together
The effectiveness of this build comes from the relationship between its major systems. The GT4+ splitter and canards establish the front aero configuration, while the 1600 mm chassis-mounted wing provides the corresponding rear aero element.
The BBS E88 wheels and AP Racing brake package support the chassis under repeated high-speed use. The GTS hood contributes to ventilation, while the OMP seat, roll cage and steering system create a more controlled driver environment.
The result is a purpose-built BMW F80 M3 where the aero, braking, chassis and cockpit components support the same track-focused objective.

BMW F80 M3 GT4+ Time Attack Build FAQ
Which GT4+ aero components are installed on Alex's F80 M3?
Alex's F80 M3 uses the Ridgeline Motorsport GT4+ Splitter Kit, four-piece GT4+ Canards and 1600 mm GT4+ Rear Wing. The three products form the complete front-to-rear aero configuration shown on the car but are also available separately.
Is this an OEM BMW M4 GT4 body kit?
No. The GT4+ system is a Ridgeline Motorsport aero package developed for the F8X platform. Its design takes inspiration from GT4 motorsport applications, but it is not an OEM BMW Motorsport M4 GT4 body kit or factory GT4 component set.
How does the GT4+ tunneled front splitter work?
The splitter kit combines a carbon front lip/airdam with a separate tunneled lower splitter. The tunnels manage underbody airflow, while an integrated channel provides an exit path for air discharged from the factory lower oil cooler.
Why does this F80 M3 use a 1600 mm chassis-mounted rear wing?
The 1600 mm wing provides a substantial rear aerodynamic surface to complement the front splitter and canards. Its supporting structure transfers aerodynamic load through reinforced mounts rather than depending only on the outer trunk skin.
What wheels and brakes are used on this F80 M3?
The car uses gold BBS E88 motorsport wheels and an AP Racing Pro 5000R front brake kit with CP9660 calipers and 372 mm discs. These components support the repeated braking and chassis demands of Time Attack driving.
Is Alex's F80 M3 intended for street or track use?
The car is primarily configured for Time Attack and track use. Its complete aero package, racing seat, full roll cage and motorsport braking system prioritize track performance over everyday street comfort.
