The APR set up looks fantastic and I can vouch for their performance having fitted them to my Westfield a couple of years back - truly awesome when you're workin em

Just back to the copaslip on the bolts issue - I was reading through the handbook last night (sad I know) and here's what the manufacturer says on page 80 of booklet 3.2, I quote
"The wheel bolts and threads in the wheel hubs must never be greased or oiled. They could otherwise loosen whilst the vehicle is in motion, even if the required torque setting is used. Risk of accident!". BTW the required torque setting is 120nm - and dont use a cheap torque wrench they're not accurate, borrow a mates expensive one or take it to a good quality garage that you know you can trust or lash out for a good wrench
