Hi All, just thought I'd share this as it may help others. Just had the 2nd year service with bolt tightening and chassis inspection at TH Whites in Swindon (UK). Car has 7400 miles - mostly non daily. I spoke to the engineer who worked on the 4c and he said that none of the bolts were out of spec. They had a 4c in the previous month for the same and he said that there were a few bolts that needed a small amount of torquing up on that one.
