website does seem a bit moody with the gigures TBH but i'm sure others on here could have advised regarding expected gains from this package before you shelled out.
In answer to the question about what figs are seen with 172s, what is the lowest etc, i saw 151 on an 02 plate once, was a girl on here called Lacey... she was pissed off enough anyway, but on the way home in convoy the clio in front lobbed off a bolt or engine part, and it hit her roof and dented it LOL. Then a few weeks later she hit a land rover head on and wrote it off! Some Clios are just unlucky.
