Built to Attack the Clock — Alex's F80 M3 GT4+ Time Attack Build
Every serious time attack car begins with a clear objective.
For Alex's F80 M3, that objective was simple: build a machine capable of delivering maximum aerodynamic efficiency, predictable handling, and confidence at speed—without compromising the design language that defines Ridgeline Motorsport.
The result is one of the most complete F80 M3 GT4+ builds to date.
Ridgeline Motorsport GT4+ Aero System
At the heart of the build is the complete Ridgeline Motorsport GT4+ Aero Kit, developed from extensive track testing and engineered as a fully integrated aerodynamic package rather than a collection of individual parts.
The car features the complete GT4+ setup, including the front splitter, dive planes, and rear wing. Every component is designed to work together to increase front-end grip, improve aerodynamic balance, and generate meaningful downforce at high speed.

Inspired by modern GT racing while developed beyond traditional homologation limitations, the GT4+ package reflects our philosophy of building functional aero without sacrificing visual cohesion.
A Purpose-Built Time Attack Machine
Supporting the aero package is an equally capable chassis.
A set of iconic gold BBS E88 motorsport wheels provides lightweight strength and timeless racing heritage, while the massive AP Racing Pro 5000R 9660 brake system delivers the braking consistency required for repeated high-speed sessions.

The factory BMW M4 GTS hood improves engine bay ventilation while preserving an unmistakable OEM motorsport appearance—proof that some of BMW's best engineering still deserves a place on a modern track build.
Every component has been selected with one goal in mind: performance without compromise.
Designed Around the Driver
Inside the cockpit, the car continues its motorsport-focused philosophy.
An OMP Halo racing seat and full roll cage provide the safety and rigidity expected from a dedicated competition vehicle, creating an environment where the driver becomes part of the chassis.
Mounted behind the MOMO MOD.88 steering wheel is the JQ Werks GEN2 Podium System, delivering motorsport-inspired controls while retaining the premium machining and engineering that define the JQ Werks platform.

The combination creates a cockpit that feels purposeful, intuitive, and ready for competition.
Function Defines the Form
There are countless modified F80 M3s.
Very few are developed from the ground up with a complete aerodynamic philosophy, motorsport-grade hardware, and a singular focus on lap time.
From the Ridgeline Motorsport GT4+ aero package and gold BBS E88 wheels to the AP Racing braking system, factory M4 GTS hood, OMP Halo seat, full roll cage, and JQ Werks GEN2 Podium System, every component exists for a reason.
Nothing is decorative.
Everything is engineered to make the car faster, more predictable, and more rewarding to drive at the limit.
This is what a true GT4+ Time Attack build looks like.
