It seems to be who by and how they are fitted, I have fitted arms from almost al the suppliers and NEVER had a complaint about a faulty arm, they are all fitted the same way with expert care and attention.
I can go along with that, about to do ALL the front end this week once my parts arrive, all from CLICKAPART,...top/bottom wishbones, drop links, disc's and green stuff pads as they work well with no dust!
Cheap parts maybe, ( except pads) but I also believe in doing the whole thing and it can be done on a budget, marrying new to old just doesn't work.
We all like a bit of DIY, but a lot of budding mechanics out there tend to fit most parts with a 2lb micrometer
, only to have unknowingly damaged the new bits going in
If you know what you're doing, you will recognize crap when you see it, so don't fit it!
Cheaps OK with me
