Unlike europe which got them listed in the 'week 45 engine and specification' update sent to VW dealers' the Uk did not. Theres no word at present in official channels when or if they will be fitted to uk GTIs. The R model will get the darker version as standard so that version will become available as spare partsfrom that i understand that they are available on the GTI in germany as an option for around 300euro! When is it likely they will b available in the UK? any suggestions?
