Thanks Terry,
The A arms are stockies but mounting points have been slotted. the guys
that did the rear alignment reacon they couldn't get the toe any closer to
zero. Rear height I think is about 270mm...I actually have closer to 2 neg
camber, once again, they couldn't get it any closer to zero.
I do have a front / rear proportioning valve fitted, will this help??
Re: youthful exuberance - yes well and truly aware of the possibility of
going off backwards into a sand trap and will modify my behaviour
accordingly :)
