blast you aki!!!! we were all supposed to stay stock together, and just theorize and dream about what to do suspension-wise! you've ruined us.... :)
but on another note, you know good and well not to refer to your cars handling as being, or approaching, "neutral". you can reduce understeer; yes. but then realizing that with an increased possible limit, the car will still lean to either understeer or oversteer when approaching or passing that limit.
neutral, to me, is still having grip when you haven't reached running at 10/10th's to see what the car does once it breaks that line....
anyway, kudos on the neg. camber, kudos on the gear (how much was that mugen setup for ya?), and have as much as mature fun as possible!
