Page 3 - FAQ

There is an old saying that I like that goes “the only stupid question is the one that isn’t asked”.

When it comes to improving your car’s performance, more than likely you have more questions than answers. I know that I do. So with this in mind, I decided to create a “Frequently Asked Questions” blog.

Part of the reason for this is that when you decide to start modifying your car, you have a lot of the same questions that we all did when we started out, and no matter what you have done to your car, more than likely you are looking for the next thing you can do to make your car go, stop, or turn faster, and you might have a question or two…

Our goal is to make this “FAQ” blog into a resource for anyone from someone that is just starting to modify their car to someone that has put in a fully built engine or two, and is still looking for an answer a question.

To begin with, we are going to put up commonly asked questions, and our answers to them. However, if you don’t see the question that you have, feel free to post it as a reply to this first post, and we will do our best to answer it. Also, if you read an answer, and it sparks another question, feel free to ask it as a reply to this first post as well, and we’ll do our best to answer it too.

The only requirement that we have is that your questions stay on topic.

Thanks for looking and please check back often as hopefully this will continue to grow into a large resource as more people become aware of it.
