In appearance because the subject is the looks of a performance thing; lighter fasteners.
Looking to buy a new box of alumium fasteners. Those come anodised so there is a choise of colours. Now I am not into gold, red nor blue but.... the gold accents on the head brace/damper do give a neat contrast as do the blue Enkei valves.
The crux is that I can use alu and black ánywhere, the others not.
Please vent your opinions ;D about colour that is. I knów that lightweight fasteners are not even márginal weight loss so call it OCD, a fetish, whatever, I agree; it´s nuts but... it´s lightweight nuts 8)

Does it look right in its surroundings. Whatever wherever that may be.
Yes, and vanilla of cark chocolate both combine with just about all. Still, a bit vanilla. Or chocolate.
