What Can AutoClass Do?

Answer Any SCCA Solo Rules Question

AutoClass covers the entire 2026 SCCA Solo rulebook — all 30 sections. Ask about event operations, timing and scoring, protests, penalties, vehicle requirements, driver eligibility, course design, or anything else in the rules. Every answer includes section and page citations so you can verify against the official rulebook.

Car Classification

Ask what class your car belongs in. AutoClass searches through over 2,300 car entries from Appendix A of the Solo rulebook to find your car's class. For example: "What class is a 2020 Mazda MX-5 Miata?" returns CS (C Street) with a link to the rulebook page.

Modification Rules

Find out what modifications are allowed in your class or category. Ask questions like "Can I run coilovers in Street Touring?" or "What tire sizes are allowed in Street class?" AutoClass checks the category rules and gives you a sourced answer.

SCCA Solo Categories

The SCCA Solo (autocross) competition program organizes cars into categories based on the level of modification allowed. AutoClass covers all of them:

Street Near-stock vehicles. Minimal modifications allowed.
Street Touring Moderate mods: coilovers, intake, exhaust, limited aero.
Street Prepared More freedom: engine work, wider tires, rollbars.
Street Modified Significant mods: forced induction swaps, aero, cages.
Prepared Heavily modified: engine swaps, gutted interiors, slicks.
Modified Purpose-built: formula cars, sports racers, specials.
CAM Classic American Muscle: domestic V8s, traditional and contemporary.
Xtreme Xtreme Street and Xtreme Prepared: maximum performance builds.

How It Works

AutoClass combines a full-text search index of the 2026 SCCA Solo rulebook with AI to understand your questions and find relevant answers. When you ask a question:

  1. Your question is analyzed to determine what you're looking for (car classification, modification rules, general rules question).
  2. The appropriate tools search the rulebook data — car listings, category rules, or full-text section search.
  3. Results are compiled into a natural-language answer with citations to specific sections and page numbers.
  4. Citations link directly to the relevant page in the official SCCA Solo rulebook PDF.

Use AutoClass with AI Assistants

AutoClass also works as an MCP (Model Context Protocol) server, so you can connect its classification and rules tools to Claude Desktop, Claude Code, Cursor, or any MCP-compatible AI assistant. See setup instructions.
