IMSA’s Battle On The Bricks Set for Six-Hour Showdown
About IMSA’s Battle On The Bricks Set for Six-Hour Showdown
INDIANAPOLIS — The IMSA WeatherTech SportsCar Championship returns to the Racing Capital of the World this weekend for the TireRack.com Battle On The Bricks, a three-day festival of sports-car racing at Indianapolis Motor Speedway featuring prototype and GT machinery on the 2.439-mile road course. The headlining six-hour race runs Sunday, capping a slate that also includes the Michelin Pilot Challenge, Porsche Carrera Cup, and Lamborghini Super Trofeo.
The 2025 edition arrives with healthy car counts across all four WeatherTech classes: 12 Grand Touring Prototypes (GTP), 12 LMP2s, 11GTD PRO entries, and 18 GTD cars are listed for the weekend—underscoring the series’ deep manufacturer and team participation. IMSA’s event page also details the track length and supporting series entries.
For fans, IMS and IMSA have leaned into the festival feel.Speedway officials are steering attendees to a “Plan Ahead” hub for parking, gate rules, ticketing, and accessibility, while MainStreet in Speedway hosts a free Thursday evening IMSA Street Festival to kick off the weekend.
On track, Friday and Saturday are loaded with practice,qualifying, and support-series races; Sunday’s WeatherTech race is scheduled for 11:40 a.m.–5:40 p.m. ET, with broadcast coverage on Peacock Premium and a national TV window on NBC. IMSA and NBC Sports list full hour-by-hour rundowns, including Saturday qualifying and the IMSA Michelin Pilot Challenge 120.
The strategic picture is classic IMSA Indy: traffic management through the infield’s technical complexes, tire life on long green-flag stretches, and late-race pit calls that can swing class podiums. IMSA’s “What to Watch For” highlights several storylines, from championship implications to potential weather variables that could jumble strategies over six hours.
Recent history suggests surprises are likely. Last year, BMW M Team RLL thrilled the home crowd with a 1-2 sweep, as Jesse Krohn and Philipp Eng led the way in the No. 24 BMW M Hybrid V8—BMW’s first WeatherTech win since Watkins Glen 2023—with the No. 25 sister car close behind at the line. A post-race technical infraction reshuffled the remaining podium spot, underscoring how fine the margins can beat Indy.
Operationally, IMSA’s supplemental regulations and event schedule—released in the official weekend document—map the paddock load-in through race day, reflecting the series’ sizable footprint at IMS and the coordination among suppliers, TV, and timing& scoring.
Between stout entry lists, a national TV window, and one of motorsport’s most storied backdrops, the TireRack.com Battle On The Bricks again positions IMS as a pivotal late-season stage for IMSA’s title fights. Expect a deep manufacturer tussle in GTP, Pro-Am precision in LMP2, and door-to-door GT racing down the front stretch to the Yard of Bricks—endurance tempo with a Brickyard twist.
