Class B (501–600 PI) is the all-rounder bracket for many Horizon players. Cars here are quick enough for festival races without jumping straight into supercar territory, which is why so many weekly events land in this window.

Expect setups that trade a little peak speed for predictable weight transfer. B-class road and street tunes often focus on mid-corner grip and clean exits rather than maximum horsepower — the cars already have enough power to punish a loose rear end.

Dirt and cross-country B-class builds need different spring rates and differentials than tarmac cars. Prefer share codes that state the discipline so you are not loading a drift tune into a gravel race or a drag conversion into a circuit event.

Browse the grid for community upvotes, open a tune page for the share code plus context paragraphs, or submit a tune if your B-class car is missing from the list. An empty grid means the community has not published a matching build yet — that empty state is intentional, not a broken page.
