There is considerable difference in road "feel" between different toe settings. Even with good shocks and suspension bushings, zero toe feels different to (say) - 2 deg.
When I installed my PSS9's, I had a quick alignment done by a non Porsche shop and initially it was OK on the road, except the car got nervous and twitchy over 140kmh. I knew it wasn't caused by worn suspension parts, tyres or shocks - all new.
So I took it to a Porsche specific shop and they gave me the following setup:
FRONT: Toe = 1,5mm, Camber = -0.6 deg, Caster = +7deg.
REAR: Toe = +2.0mm, Camber = -2deg.
Wih the front toe increased from 0 to 1,5mm the nervousness dissapeared and the car now feels really good at all speeds.
And don't forget that the rear alignment has a marked affect on the cars feel too.
