Due to continued supply chain issues for the approved Bender ISOMETER® IR155-3203 or IR155-3204, the Formula SAE Rules committee is allowing the use of two alternate IMDs noted below.

Approved equivalents for the 2023 competition year are the Bender IR425 or Sendyne SIM101MLQ.

The Sendyne SIM100MOD is NOT approved.

Any other proposals must be approved by submitting a rules inquiry.

The Formula SAE Rules committee is open to receiving recommendations on any IMD that meets rules EV8.6. Teams can submit recommendations via rules inquiry. Any interested companies please email Formula SAE Program Manager, Kaley Zundel at [email protected].
