NASCAR has rolled out a new front‑bump‑bump rule that will strip foam from both front and rear bumpers for Cup Series cars at four upcoming short‑track events.
Rationale Behind the Foam Removal
The modification aims to deter drivers from violently slamming into the back of a leading car. By eliminating the cushioning foam, any hard contact will now compromise a car’s aerodynamic packaging, making aggressive bumping more consequential.
Track Schedule
- North Wilkesboro – July 19
- Richmond – August 15
- Bristol – September 19
- Martinsville – November 1
Eliminating Foam and Re‑engineering the Front Bumper Struts
Teams must first remove the foam inserts from the front and rear bumpers. Following the removal, the four front bumper struts must be readjusted to accommodate the altered bumper geometry. The bulletin supplies a step‑by‑step procedure for the strut modification and presents an illustration of the final bumper assembly once the changes are complete.
