2005 JCW Mini Cooper S
 

Hello! I'm new to this forum but trying to learn more about my car and get ideas. I want to start modifying my car but not sure where to start, the JCW already has part that are upgraded from the regular S. I just put a new head gasket, a new supercharger, new hoses, water pump, etc (basically the whole cooling system)

Open to all suggestions and ideas, cosmetic and performance.
