Those are the main things that I can think of really,
Everyone goes for new alloys, and with new alloys always means some lowering.
Milltek or Blueflame exhaust? If you are going for a new exhaust then maybe a new intake as well to give it the maximum benefit.
Maybe get a bit of carbon fibre in there too, inside or out, its all good.
Oh, and that remap does sound good too, thats something I need to sort, 170bhp does sound pretty good, is yours the 1.6?
Colour coding is always a surefire thing too, but on a black car not really essential IMO.
