Just in case you forget which parts you have fitted to your car you can put a shopping list down the front door. These can look cool but there is one very important condition that I just wish people would follow.
All modified car part maker logo stickers are available but please, please please only put them on your car if you have used their parts! I’ve seen too many non Japanese cars (usually the mothers hatchback) with stickers from makers that only supply Japanese cars parts.
Stick to the same colour and choose grey, silver or white on dark paint and black for lighter colours.
