update on the ultimate coilover project:
based on feedback of the prototypes and experience with the initial production, i did many tweaks to reduce weigth, make production simpler and faster. some sacrifies had to be done though, native support for the rx7 caliper was dropped in favor of free brake setup changes, better material for the stub axle and weigth saving. instead you will get additional rx7 caliper bracket made of 7075-T6 alloy, which will be a tweaked version of the classic design, backwards compatible with standard struts. all in all, installed, the total weight will be less than with the native bracket made of steel.
at the end, the whole unit will look much more refined, much nicer.
