Ace

Ok so here's the deal. FRSport still sells these for S13s with open diffs. My question is are they still around because it appears the north American website no longer exists. I understand it's ATS in Japan but I just wanted to know if there is still support for the parts should something happen. Most forums speaking of it are back in 2011. Just want to make sure I don't end up making the mistake of purchasing a discontinued part
