Suggest a Calculator
Have an idea for a calculator, converter, or finder we don't have yet? Tell us about it.
What makes a useful suggestion
The best suggestions describe a real job. Instead of "a tire calculator", tell us what you were trying to work out, which numbers you had in hand and which you were missing. A request such as "I know my lift height and my wheel width and I want to know how much clearance I have at full lock" is easy to turn into a working tool. It also helps to say whether you work with US or metric units, and whether you build engines, restore bodywork, set up a home shop or tow with a truck.
What we look for
- A clear formula or lookup. We build tools where the answer can be calculated or taken from a reliable table, not where the honest answer is "it depends on your car".
- Something people search for. We check what garage and shop questions come up again and again so that new tools help many people.
- A fit with the site. Engine, drivetrain, fuel, wheels, shop and body, finders and converters are the main areas, and new ideas that fit them move faster.
What we can't build
We don't build tools that diagnose a vehicle, give legal or insurance advice, or claim to predict exact dyno numbers or lap times. Those depend on too many things that no form can see. If your idea is closer to a guide than a calculator, tell us that too, because the guides section grows from the same questions.
What happens next
Every suggestion is read. Ideas that come up more than once, or that fill a clear gap, go on the build list. We can't promise a reply to each one or a date, but if you leave your email we will let you know when a tool you asked for goes live. In the meantime, browse the full list of tools, the finders and the converters and lookups, since the thing you want may already be there under a different name.
