JoelSee many queries and answers on proper offsets for running aftermarket wheels on cars like my '04 GT3. I'm preparing to buy a set of wheels with 9" fronts. The two manufacturers with whom I'm talking, recommend a 45 mm offset compared to the 40 mm offset with the stock 8.5" wheels.Can you explain why the difference in offsets? I guess my question is a more general one in that I'd like to better understand the relationship between the different suspension components, wheel size, and offsets. E.g., in many of your replies, you note that a wheel of a certain size with a certain offset fits because more neg camber can be run.Or can you direct me to a book on suspensions that explains all this?Thanks
