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.

1987-93 V8 Mustang Spindle Tech

1987-93 V8 Mustang spindle has both similarities and many differences with the first generation Mustang spindle.


  • Brake calipers, pads and brake hoses were changed from the earlier spindle, although superficially similar in appearance.
  • Tapered roller bearings.
  • 1-piece hub and rotor assembly.
  • 11" rotor diameter.
  • Calipers are most similar to those found on the SVO Mustang, but have a smaller piston diameter of 60mm.
  • 1987-93 V8 Mustang calipers and the SVO calipers are interchangeable as far as mounting on the spindle goes. While they share the same pad shape, the inboard retaining clips differ because of the different pistons.
  • Unique ears for mounting the stock caliper; aftermarket calipers cannot be installed without significant modifications to the spindle.
  • Mounting ear for the strut is 0.230" (5.9mm) thinner than the first generation spindle.
  • Boltholes for the strut mounting are 0.130" (3.3mm) further apart than the first generation spindle.
