The long answer is that the only reason that Koni ever made them is because I was friends with a couple of guys at their Northern Kentucky production facility and because SPS took it upon ourselves to send them several sets of stock cores to be modified.
But within the first year, Koni was unable to get product out of their production facility. All POs took forever to get and inevitably had something wrong when they arrived in Dayton. So we gave up.
If someone else is willing to invest in a batch of cores and place a large enough order, perhaps they would be willing to try again.
If you just need one set and are willing to pay a retail price, contact TrueChoice Motorsports in Columbus Ohio. If you send them one set of cores, they will make you a custom set using Koni parts.
