IMO no need for custom shocks. Koni Yellows will get you there. Crash bolts with autox alignment, sway bar (TRD or ST, kind of a driver preference I suppose) 710's or S04's, and maybe a muffler swap. That's about it. Now it's all about seat time.
(who loves living in warm weather now, even though I have committed a sin by driving a CS Miata!)
I am not sure about the front sway because it made my Miata drove like crap on the street. Yes the car definitely drove faster, but it felt like crap because of the soft soft springs. I hope MR2 will be better
There are two bolts that attach the knuckle to the strut. Normally, those bolts fit exactly and allow no play. "Crash" bolts are smaller and allow play in the knuckle to strut fit so that the mechanic could add or remove camber back to factory spec (typically done after a crash). Autocrossers use them to get more camber because they are allowed by the factory for repairs.
