Hey everyone,I wanted to share my G82 M4 track build, which Ive named Project Carbon Arrow. The goal for this car is to compete in time attack series and amateur endurance races. The build is focused on maximizing mechanical grip, reliability, and driver safety, while still keeping it raw and engaging. Theres still a lot of work ahead (especially in aero), but heres where we are right now.
