Not exactly, but spending money on 18" wheels & tires when you want to go fast should be the last thing on your list. Put the money into your new turbo, afc, front mount, etc. Everyone in this thread has been pretty welcoming so far, but the local DSM boards and folks will probably stereotype you and not give you any help if you show up with 18" wheels and a big wing, even if you do have good intentions of going fast. History has shown around here that people who focus on those types of cosmetic things don't have fast cars.
