NHRA Releases SFI 25.x Chassis Specification Updates

NHRA Championship Drag RacingAs posted on nhraracer.com –

SFI has recently revised their 25.x chassis specifications.  These new specifications will be enforced immediately on all newly constructed chassis.  For chassis requiring re-certification, these revised specifications will not go into effect until January 1, 2019.

This will give the racers and chassis builders time to purchase the revised specs and bring their cars into compliance.
