I just wanted to post a quick thank you to the above members in particular and many others here. You have answered my questions directly and provided information in other threads that I read while searching. When I found this site at the end of last year, I knew nothing about the modifications you can make to the Grand Prix's. Now I have one that accelerates faster, corners better and stops quicker than it did when I bought it. It may not be as cool as a Civic , but I like driving it and there is plenty of room for the family. It would never have happened without your help. Thanks.
