I needed to have my MCS dampers rebuilt relatively quickly as I had an event at COTA coming up. My usual go-to shops were busy with race season and couldn't spare the space to have my car sitting in their shop for 7-10 days while my dampers were being rebuilt so I tried MPorium BMW.
I had heard of Coulter from his thread here re: the aluminum undertray replacements that he fabricates to replace the crappy OEM ones. Link here -

Coulter at MPorium BMW got me in and did incredible work. In addition to sorting out a few other issues I had, he fabricated an aluminum under tray that would accommodate my brake ducts. Check out the pics. Amazing work!
His undertrays and mechanic work are of the highest quality so consider both!
