Well ARP have my vote of confidence for aftersales service. Having just rebuilt my head for the 2.1 16v I was putting all the bits together only to find I have lost 1 bloody 12 point nut from my ARP headstud set. I emailed ARP in the states on the weekend asking if there was someone who'd have one in stock in the UK. Fairplay. Nigel Atkinson ARP European Operations got in touch today saying that there was 1 already in the post and I'll recieve it on Wednesday free of charge Well, what can I say. Well done ARP Saved my bacon and gets me back on the road
