The 2025 Toyota GR Cup season fires to life at Sonoma Raceway.

From March 28–30, Karl Forman makes his series debut at the wheel of the #03 Precision Racing LA Toyota GR86, taking on Rounds 1 & 2 at one of the most technical road courses in the country. Sonoma’s 12-turn, multi-elevation layout carves through Northern California wine country, blending blind crests, heavy braking zones, and fast, flowing corners that reward precision and patience—right in Karl’s wheelhouse.

Adding to the drama, rain is in the forecast for the opener, promising a classic wet-weather twist. With Karl’s reputation for being strong in the rain and incredibly consistent over a race distance, the changing conditions could turn this into a showcase of pure racecraft. Across the weekend, expect tight GR Cup battles, strategic tire calls, and intense qualifying sessions where every lap on a damp track counts.

Whether you’re trackside in Sonoma, watching from home, or following along on social, this is the beginning of Karl’s Toyota GR Cup journey. Check back here for his full weekend schedule, qualifying results, race recaps, and behind-the-scenes content from the season-opening Sonoma Raceway round.
