Just wondering if any special parts or spacers are needed or if the 18x10" deep dish Bullitts are a direct bolt on? Do the stock center caps fit the larger wheel or do I need new ones? Was thinking of getting these for my car.. http://www.latemodelrestoration.com...g-Anthracite-Deep-Dish-Bullitt-Wheel-Tire-Kit Also, anyone who has switched to this size rim.. Have you noticed any performance difference in your car? Does it ride a lot rougher due to more un-sprung weight? Just wondering, thanks.
