Certainly can't complain about the quality of Wossner, if they good enough for German touring cars and the likes, friend of ours had some custom sets through J-tech Motorsport, I picked them up for him and Frost in Ipswich uses them for a lot of his builds.

Can't comment on PEC rods as never seen them or personally know anyone who's used them, but defo recommend Wossner, not many cars they don't do, full list is on their website AFAIK
