I know that the official whitline settings for this kit are 1-1.5 degrees negative camber with zero toe at the front and 1-2mm of toe out at the rear for fast driving.

What I want to know is a couple of things what is the implication for stability under braking of changing from 1 mm toe in to zero toe? Do the stiffer bushes negate the need to run toe in?

What effect does the toe out have at the rear? The concern I have is that the settings have been created for a UK/Australian WRX which doesnt have as much of a rearward torque bias. Are these settings likely to make the car very tail happy? Or does the amount of movement of suspension parts under power negate this?

I have experimented with toe out on the rear and I would not recommend it because it makes the car very unstable at speed however it does make the car more neutral on wet roundabouts and tight curves. Toe in on the rear increases stability at motorway speeds but does increase understeer.I have found about 0.5-1.5 mm of toe in to be the best compromise.
When under power at higher speeds,there is not enough torque at the wheels to distort the suspension parts so I would imagine your car would be unstable if the rear had even a small amount of toe out (probably more fun on roundabouts though)

I had the ALK, 22mm sways F+R, steel endlink F+R + rear camber pins fitted last friday. Wnet for -1.1 and no toe at the rear and -.4 (for a start) and no toe at the front. Car still feels very responsive and stable. Didn't opt for toe out at the rear as it might make the car unsettled under braking. It helps turn in of course, but it also make the rear more twitchy.

Nico,

how stiff does the car feel at the rear. The STi has very stiff suspension but 20mm roll bar and plastic links in the rear.

Also did you fit uprated bushes on the anti-roll bars?

Cheers,

David

Yes,

Poly urithane bushes come with the sway bars.

Ride doesn't feel hard at all. Just firm, very stable, more solid. When cornering hard you really feel the reduced amount of body roll. Where as with the normal suspension you would waggle (relatively) it's now firm.

I haven't tested it to the max though on roundabouts (I love roundabouts). But as far as I've gone no indication of oversteer.
