Overview

  • Jack Aitken, Earl Bamber and Frederik Vesti led the No. 31 Action Express Cadillac to victory, pacing 210 of 243 laps to snap a 23-race drought, with Wayne Taylor Racing’s No. 10 taking second for a Cadillac sweep.

  • The No. 60 Meyer Shank Acura lost pole in post‑qualifying inspection for a bodywork infraction, started last in GTP and recovered to third with Tom Blomqvist and Colin Braun.
  • Class winners: TDS Racing in LMP2 for a third straight Indy triumph, Ford Multimatic in GTD Pro with the No. 64 Mustang, and Inception Racing taking its first IMSA GTD victory with the No. 70 Ferrari.
  • In the GTP standings, Porsche Penske’s No. 6 finished seventh and carries a 131‑point lead over the No. 7 into the Road Atlanta finale.
