Ah right so its still quite common today then, was talking about it the other day with someone so thought i'd get some opinions on how much its actually used today etc!!
Funny u should say that about cometic as the 2 main builders i spoke too a while back said not too use it, 1 prefers raceline whereas the other said WRC all the way!!
