Well I have been looking to get bullits for my ride, either the gray color ones or te blacks and I noticed they have 17x8 on some websites and 17x9 on others. What size came on the 99+ stangs. Im thinking to go with the 17x9 but want to be sure. Also they say the 17x9 has a shipping weight of 33 vs 23 for the 17x8 thats 40 lbs extra weight i dont want!!
