About FitMyBuild

FitMyBuild started in a garage, not a boardroom. It's a community-driven database that answers one deceptively hard question every builder runs into: will this part actually fit my car? Engine swaps, suspension, brakes, drivetrain — the knowledge is scattered across forums, group chats and half-remembered threads. We're pulling it into one place that's searchable, verified, and free.

1

Builders submit

Enthusiasts document swaps that worked — the parts, the fitment notes, the gotchas.

2

The community verifies

Others who've done the same swap confirm it, so entries earn trust over time instead of taking one person's word.

3

You build with confidence

Search, compare, and follow step-by-step DIY guides before you spend a dollar on parts.

Why we're doing this

We're enthusiasts first. The site is built and maintained by people who spend their weekends under the hood — currently focused on Honda, with more platforms coming as the community grows. Every entry is here because someone actually did the work and wanted to save the next person the headache.

Want to help — or partner with us?
