Hi JD I have been watching your progress with pleasure, your a talented man with cars.
As for the fuel cover badge, hard one it does look good on black or with carbon fibre, but im not sure on the red.
As a thought an alternative idea what about getting your daughter to do a shadowed or faded look logo for it, ie a darker red than car colour?
Or a clear one showing off shinny fuel cap hehe.
On side note reference to OEM 360 seats. Pug seat runner is 520mm outer edge to outer edge, OEM 360 is 460mm outer to outer so custom runner plate needed.
Keep up the excellent work.
