I'm kinda new to this suspension thing. A friend has a brand new set of x2c Upper and Lower control arms (lowers are adjustable). What are they worth? Are they any good? I've searched the net. Seems the place is out of business? Also I've read something of a bad design batch? I need control arms (adjustable if I can afford them) but I'm also on a tight budget. The engine project kinda cost me a lot. Recommendations are welcome!
