Thanks for the replies. I popped into my local Slow Fit centre today. They guy said "it was against company policy to fit anything they had not sold!" I then went to another local ETB fitter who was well up to doing the job. They sprayed the bolts ready for me to pop in tomorrow morning. They said bung them about 15 quid Also said they had done one of these before and it sounded awesome. Possibly somebody on here?

I'll post one final entry in this thread to give my opinion tomorrow
