No worries, yes, i'd say 2, maybe 3 out of the whole lot are a bit odd. By odd i mean the resistance they put up when pushing the rod by hand felt moreso soft/hard compared to the others. I know for sure that one of the fronts out of the four was knocking. i got fed up with pissing about. I also have a set of springs that were sold to me as u.k spec but i didn't feeel any difference between them and my stock TT ones. Although the fronts do make the car sit a bit lower than the tt ones. I would assume that they are stock NA springs.
Actually, just remembered my stock tt front ones are tokico and the others are kyb.
Anyhow, if nobody wants them after ive got some bilsteins, they will be binned. So your welcome to them.
