I've applied for a spanish patent because it was cheap, so first step is started, I've also produced some items and tested in my buggy, the results are great, now I'm working in some samples for a 1/5 touring car manufacturer, test will be done during next month, but I'm also sure it will work, those guys told me that they have never seen something similar on the tracks, and allthough is something simple they really like the idea and want to make the performance test to install it as a standar part of their cars.
The only problem to release the product without patent is that I'll be the first but as I don't have sales structure I'll sell just some items as aftermarket parts before all the big fishes start producing at lower prices than me. I think that there are some governament helps for spanish research and development, I'll call them tomorrow, the patent for usa only is about 6000$ that means a patent for europe,USA and Japan can reach the 20000$ easily, register a name cost about 1400$.
I have a strange feeling, I'm excited that something done by me can work and be sold worlwide, but at the same time I'm worried about other people will steal the idea and make money with it. I don't pretend to become rich but it whould be fair getting some money for the time and efforts invest on it.
I'll post some drawings and test results here once I decide what to do.
