I'm still very much a Rookie with the Altezza, but I've always monkeyed about with springs, dampers, bushes etc. (let's call it 'suspension, eh?) on my old Opel Mantas and Asconas, and found that having the front a tad higher, perhaps 15 to 25mm tended to lead to a more obedient front end which would turn-in easier, and lots of lovely traction to the driven-wheels at the back end. It may LOOK really killer to have a car with it's nose down in the dirt and its' tail high, but it likely won't do it any favours in the bends or off the line.
My Alfa-Romeo 75 TwinSpark is blessed with virtually 50:50 weight distribution (being a transaxle car, with that engine slammed right back against the bulkhead) and they are known for being one of the better-handling cars of their generation, capable in particular of jogging-away from bigger-engined cars - which are a lot quicker on paper - in the twisties of the Nurburgring. I guess that having gone to the expense of fitting coil-overs, a session of 'corner-weighting' wouldn't go amiss, to try to equalise loadings for each wheel. The ever-practical Colin Chapman used to use four sets of bathroom-scales when optimising his delicate little Lotus Sevens, but I'm sure our cars would need something more substantial under them.
