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.

Guide to Choosing Spring Rates and Dampers

1979-2004 Mustang

How do I choose which springs to use?
Choose springs that provide the handling characteristics and ride quality you want from your Mustang. To determine that:

  • Decide on the performance goal for your Mustang.
  • Consider how you'll use your Mustang most of the time; you want to optimize it for that type of driving.
  • Consider what level of ride quality you want, and then decide what (if any) compromises you'll make to achieve your performance goal.
  • Decide between stock-location springs, a conversion to coil-overs, or a combination of the two.

Which MM dampers go with which springs?
Choose your spring rates first. That choice dictates the damper series selection.
