Cheers Chris, Not fixed down to a date but would be nice to register in March for the new 17s. Paperwork goes off today special delivery so hopefully they're speeding through after Christmas...! Caterham have no experience with my local station so i'm just going to chance it. Worst case is that it fails and I have to pay £90 and wait. Hoping that a boot full of tools, trim and a nice attitude to the tester should be enough. Found a chat full of Locosts/Westfields that had passed there no issue and people commenting that they were allowed to make adjustments so we shall see! Jason
