This will be be a "frugal" build. Not cheap because spending money where it makes sense and saving where it makes sense is not being cheap. So yeah, Alex's springs are on the very short list. I can do their regular drop in kit or a beehive drop in kit. the beehive kit is like $50 more.
Most of the time the engine won't see much above 4000-4500 rpm. Once in a while it will get run out to 6000. Beehives seem to be more useful at higher rpms.
