MM Coronavirus Update

We’re changing our phone hours to 9:00 AM to 3:00 PM Pacific Time (Monday-Friday, excluding holidays) so we have more time to process orders and get them out to you.

Please be aware
Our supply chain is suffering major pandemic-related disruptions. Many of our suppliers shut down for a time, and like us are operating with reduced manpower. Meanwhile, demand for MM products has skyrocketed. Thank you! We’re a small company and we regret our website isn’t fancy enough to inform you of back orders when you buy something. Please understand that we’re working as fast as we can to fill your orders.

UPS Shipping Times As of March 24, UPS no longer guarantees the shipping time for any shipment. i.e., expect shipping time to lengthen.


Although our operations are slowed due to the Covid-caused collapse of our supply chain, please place your order, as we are shipping by first-come, first-served. Our Tech and Sales staff are available by phone and email. Thank you for your patience.

MM’s S197 Test Mule, v1.0

This extremely-yellow Mustang was our first S197 R&D car. Acquired by MM in December of 2004, we tested it at Buttonwillow Raceway before its first oil change. While we used it primarily to develop our S197 parts, we installed a unique suspension as a design study for display at the 2005 SEMA show. We replaced the 2005 in early 2014 with Test Mule v2.0, a 2014 model. This 2005 still visits us occasionally. Its new owner is local, and uses it as his track-day car. He comes by when he needs new Hawk brake pads for the track. Photo by John Thawley III.
