RACER video: Robin Miller with Bill Simpson & Kenny Koldsbaek

Kenny Koldsbaek lost his good friend Jason Leffler in a 2014 sprint-car crash before he could get a full-containment seat finished to protect a driver's left side. Following Dave Steele's fatal crash earlier this year, Carbon Kenny called safety pioneer Bill Simpson and they went to work developing the safest seat possible for a sprint or midget driver.

Koldsbaek and Simpson show Robin Miller their new seat design for sprints and midgets.
