Hmm well the only advice I have, regardless of who the company is, you get what you pay for. QA1, PST, firm feel, Hotchkiss are all. Good high quality parts.
That said, I went the el cheapo route, ordered from rock auto. By the time I was done, the pst Kit was cheaper. But that was for the full front only kit. I did have a couple issues with QC including a stretched and bent Upper Ball joint.
