WolfKatz is NO LONGER in business as of August 2015. We are thus no longer making direct sales (online shopping cart is shutdown). TwosRus has agreed to pick up production of all parts from this point forward and will contiue to support and distrubute them as required. Please see TwosRus (www.twosrus.com) or our other distributors (www.wolfkatz.com/distributors.php) for all your WolfKatz Product needs. If you need replacement parts or tech support with an existing WolfKatz product, please contact TwosRus or email tech@wolfkatz.com. It may take up to 1-2 weeks for me to respond. I will leave the site up as long as possible as a reference for the MR2 community. Thanks for the great 10 years!
