BaT Auction Success Story: bamiot’s Sunburst Gold M3 Boomerang — Explained
This Success Story comes to us from bamiot, who won this Sunburst Gold F80 M3 from casciomotors in a December 2025 BaT auction:
I had the fortune of winning this 2016 Sunburst Gold Metallic BMW M3, one of just two F80 M3s originally collected via Euro Tourist Delivery. My younger brother originally built it for a client, who turned and sold it—it’s the second of his BMW builds that I’ve won. In this case, my brother and his shop Parts Score in Scottsdale, Arizona, had previously installed Pure Turbos Stage 2 turbochargers and KW4 coilovers, among other tweaks. The car had been further modified after a subsequent purchase in 2016 by other shops in California, I believe.

After I won the car, the seller’s agent delivered it to my brother at Parts Score. Given our intention to boost the already modified engine with an E85 flex tune, we installed a Euroklasse 4-pin crank hub kit and performed a few more mods.



The list of mods included:
- Replacing the dark blue HREs with BBS LM-Rs
- Threw on the correct PS4-S tires out back and established the car’s aggressive yet driveable stance
- Added BMW M Performance carbon fiber front splitters, side skirts, and front lip
- Installed a CSF top-mount intercooler
- Replaced the diff bushings and converted it to an upgraded double mount
- Performed a flex fuel/big turbo tune through Paul Johnson Tunes on the dyno

I am waiting on a new carbon trunk spoiler and rear diffuser to match the other carbon pieces.
