front end setup for the Spider...

[Godfrey DiGiorgi <ramarren@domain.elided>]

When I examined the old tires taken off FrankenSpider, they were a 
bit worn on the inside edge. Fitting the new Yokohama 
AVS-Intermediates has improved grip enormously, it's much more fun 
now, but the steering feel has taken a bit of a jump backwards. It 
seems much lighter than it ought to be and there's a bit of a 
tendency to wander on grooved freeway pavement. Also, when I hit the 
brakes hard, particularly in the rain, there is a tendency to pull a 
little bit to one side or the other.

This all sounds to me like I have too little toe-in. The spec it was 
set up to is supposed to be
   Caster: 2.2 degrees positive
   Camber: 1 degree negative
   Toe in: 0.80-1.60mm

I noticed last evening while reading through the appendices of the 
Alfa Ricambi catalog that the nominal front suspension setup for the 
Spider should be between 3-4mm.

My question to suspension gurus:
Do you think that the additional 2mm toe-in greater than what my 
current set up is supposed to be would improve the steering feel and 
stability? Or is there something else I should be looking at?

many thanks,
Godfrey
