I to will also be waiting until end of april before Z is on the road.
This brought some new things but nothing as crazy as you or jason.
Just a new shift knob, stance coil overs, whiteline front sway, tinted part of tails and a '13 Nismo front bumper but that will most likely be next winters project - the body change!
However the builds you guys have on the go I am dying to see! This year should bring some awesome shows!
