Build history
The car is a 2003 Mini Cooper S R53 in British Racing Green. It is a manual, no-sunroof car. I bought it as a fun street/autocross/track project and documented the build over time on https://www.alsoranracing.com/
I built this Mini to be a competitive autocross / track day car that is capable of being driven to and from the event. It competed in One Lap of America twice (2023, 2025), survived the transits, ran the track sessions, handled the abuse of our terrible interstates and roads, and won the Retro class in the 2025 Tire Rack One Lap of America.
