it does run abit hotter but prefer it to look standard i'm going to run 2 fan's on the rad. and some heat wrap on the exhaust manifold and downpipe. the black wheels were rs2000 wheels. what's wrong with people black wheels just dont suite my car. silver make the paintwork stand out., if you had paid alot out for 2 full resprays and the wheels made the paintwork look dull, then i'm sure that you would change the wheel's. thanks for the comments
