There are a fair number of components and facilities that are improved versions of the normal kind and require a racial tech trait. All of them have an abbreviation for the racial trait in parentheses after the component/facility name. One thing I really like is how Adamant does Propulsion Experts - it uses a Quasi-Newtonian Propulsion system, and the PE version of each engine has one more standard movement point; this translates into a 100% (very early game) to 16% (extreme late game) overall speed boost rather than a constant +1 movement point, though you can get the stock Propulsion Experts effect too, with Transdimensional.
