Thing u have to remember is yes montune as well as karl do know their stuff BUT they have spent loads of money and development over the years making/testing long studs etc so of course their gonna tell u their needed!!! They need to make money out of them lol, if they said their only needed on 700bhp engines for example they'd loose alot of money/customers whereas Karl saying not to use them isnt making him anymore money out of it..................

No slagging long studs off thou as the block in my car was already machined for them so have 6 long studs and a wrc gasket in mine
