Class A covers 601–700 PI — competitive street and road pace without the extreme aero and power of S1 and above. These cars reward precise brake bias and differential tuning because small mistakes show up immediately in lap times.

A-class events often mix flowing highways with tighter town sections. Setups that keep the nose planted on entry and still put power down on exit tend to win community votes and feel trustworthy when you paste the share code.

If a tune feels nervous under trail braking, check whether the author aimed it at road racing or aggressive street. Touge-oriented A-class builds may rotate more than a stable circuit setup, and that difference matters for festival playlist events.

Filter by discipline, open a detail page for context paragraphs and the share code, and use Submit when you have an A-class build worth sharing. Guides on PI classes and tune types explain the bracket if you are still choosing a car.
