Instant-G is a full service shop that also designs and manufactures parts. We can change your oil, your engine, or your life!

What's  a product without a service?  Not much.

We provide consulting and tech support on everything we sell, and we don't sell anything we haven't installed.

We have done quite a few whole car builds... and can engineer a comprehensive solution where all components work in harmony.

In addition to what we do, it's just as important we know what we don't do.  Paint, bodywork and interiors are really not our thing.  We can make recommendations, and fit bolt-on bodywork necessary for optimal performance, like wings, splitters, etc.  We can also make solid recommendations for shops we work in concert with for complete solution that works for you.

Part of what we do is make sure you are getting not only something that works, but that works for your application, and is financially appropriate.
