I have just purchased a 05 Mustang V6 Convertable ( White with Red leather). Picking the car up from the dealer on April 25th. I would welcome some advice on modifications I am interested in. I have already ordered a set of 20" Falken Koblenz rims (polished) with some Nitto 555 245 tires. My dealer assures me they will fit no problem, but the local mod store ( not really a wheel dealer) suggested they would rub a little.????? I also want to add a cold air kit. What is the best kit available and where can I order it from?
