Just literally had my MOT and had the same thing, was only advisory. Going to upgrade them in January probably to dba t3 discs, but not going to stress about it until then.
Had mine since February, love it! Good service, check wheel alignment, very good tyres, check paint work. Other minor glitches as shown in the videos, but these motors will make you happy as long as you look after them, happy hunting.

Found this?! Not a clue in shipping? Have emailed them. Thoughts?
I do like the looks of the fuji, tips are massive though? Someone told me today, that the Nismo S tune is the holy grail but not many around? Definitely alot more research to be done. Cheers for all your advice though guys.
