Bought new QA1 K-member, UCA, LCA, and strut bars from Summit. Had a fitment issue with the strut bars (LCA end is 9/16 and the LCA opening is 5/8 so the bars would not fully tighten up), so went to the QA1 website and filled out a contact request. No response after several days. Their website also said to email email@example.com for tech support. I did that with no response. I finally just returned the strut rods to Summit and got a refund then ordered PST rods. When I got the PST bars, the passenger side went in like it had eyes. The driver side went in the LCA, but the K-member side was an inch or more below the bracket and would not line up no matter what I did. I called QA1 and spoke with someone who then referred me to their "fitment" dept. Explained the issue. He spoke to some people then emailed me saying they would send a replacement LCA and I was to recycle the bad LCA. I emailed him asking for a tracking #. No response. I called and left a message, no response. I called QA1 again and spoke to another rep who said the rep I was working with was out at a show. He would check into the situation and let me know. No word. I know it is the LCA because the strut rod works perfectly when I test fit my original LCA. Car has now been down for weeks. What is up with these people?
