if you have the 180 KPH standard dials you will just need the g/box convertor, and cover up the kph sticker with thre mph sticker supplied.
if you have the 110mph dials you either need to replace them with standard dials and use the g/box convertor OR dont touch anything and stick to not going over 110mph
yup just put the old 180kph dials back on then fit the g/box convertor (there is a guide in the technical section)will take you literally 5 mins. then will be limited to 180mph lol as if it will ever go that fast... not sure how much the convertors are from the traders but if i can remeber from sva they are the cheapest!
