Welcome. You'll learn a lot if you take a more in depth look at some of the posts by older more mature members who have been through 2 or 3 GP's most likely. As a general rule of thumb, as with anything else, when you want to do anything, research, research then research some more. There are no ill effects to being "over-informed" as opposed to not enough when it comes to your car. Other than that, enjoy, I invite you to make a member ride thread!
