KW is the only company currently developing anything. Can new items be brought to the market? Yes, but the only way for an aftermarket to grow is for the community to support it. Fact of the matter is 20-30 people may say they want X product, but when it comes time to collecting deposits and waiting 2-3 months for R&D and manufacturing, suddenly it's only 2-3 people who are still interested. I'm always happy to assist in and talking to my HUGE list of contacts in the aftermarket business and finding quality companies to develop parts for us, but again the support needs to be there. I hate wasting my time, their time, and your time with people who are simply not serious about what they want to do with their car.
This is why the Maserati and Ferrari aftermarket continues to stay at ridiculous prices, low demand + lack of competitors = high priced items that are not readily available.
Think Eurotek ECU, I reduced the price of that item almost 35%, whenever I have the type of buying power of quanity of customers standing behind me, I can contact these manufacturers and bring them down from la-la land into a realistic world. If I had 20-30 non sky-hook owners that were actually serious about springs, I could contact a major spring manufacturer and have them develop a spring for $400-500. But when I have 2-3 customers they have no interest in doing it, and the companies that do will gouge the prices.
