If the R&D took longer than a few days for the plates, I would be very surprised. The plates not coming out a month after the lowering springs were introduced has nothing to do with the R&D time spent. This my friend is not some new manifold that would take a huge amount of R&D to design. We are talking about rectangular metal plates and bolts. Almost all of the data required to produce these was already gathered for them. Camber shims have been available for many cars for a long time. So this wasnt some new idea. Give me a break is right. I fully understand the R&D process. Some things take my company years to develop, some things take days. Lets try and keep things in perspective here.
