Hey Product Hunt! 👋 I'm excited to share BoltPatternHQ with you today. 🚗 The Problem: Every time I tried looking up wheel specs or bolt patterns for project cars, I ended up on legacy websites that are painfully slow, flooded with obtrusive banner ads, or buried behind complex paid paywalls. Worse, almost none of them provide clean, standardized datasets or APIs for developers building modern automotive apps. ⚡ What we built: BoltPatternHQ is designed to be the fastest, cleanest, and most accurate wheel fitment database on the web: - Instant OEM Specs: PCD (both metric and imperial matching), center bores, offsets, and torque specs for 10,000+ vehicles (1992–2026). - Cross-Compatibility: Quickly find which wheels can safely swap between different car models. - Developer-Friendly: We don’t just serve web pages — we provide a native MCP (Model Context Protocol) server so AI agents can query wheel data directly, plus downloadable master CSV datasets for developers and shops. We'd love your feedback! Try searching for your daily driver or project car, and let me know what other specs or features you'd like to see next! 🚀
