Default Widetrack Geometry

Hello everyone,

Thinking of taking my car down to Abbey Motorsport for a proper alignment/geometry set up but can't seem to find a set of geometry settings online. There's a lot of advice knocking around for STI Blobs but no mention of the supposedly revised set up the Widetrack got from factory?

***EDIT***

Found the info, please see below:


For a DCCD car:

Front Camber (make sure it's equal side to side)

Minimum -1 10’ Preferred -1 15’ "Track" -1 20’ / -1 30’

Front Toe-in (Total) Minimum 0 02’ Preferred 0 06’ Maximum 0 10’

Front Caster Standard Subaru (more is good)

Rear Camber Standard Subaru (make equal side to side if at all possible)

Rear Toe-in (Total) Minimum 0 06’ Preferred 0 10’ Maximum 0 14’

Thrust angle Minimum -0 01’ Preferred 0 00’ Maximum 0 01’

Non DCCD car is the same except:

Front Toe-in (Total) Minimum 0 00’ Preferred 0 01’ Maximum 0 03’

Rear Toe-in (Total) Minimum 0 02’ Preferred 0 6’ Maximum 0 10’

I would run a bunch more camber than that, the above look like prodrive settings.



Try to keep slight amount of toe on front (really little) and even less on rear like 0.06 front and 0.03 or 2 on rear (which goes hand in hand with the above)

Camber around 1.6 or more on front and around half a degree less on the back.

before going to alignment I would try and extract as much castor as possible.



I currently use 2 deg of camber on the front and 1.6 on the rear, but that's fairly aggressive, (I still get even tyre wear with this but don't do a lot of long journeys)

Thanks for the advice all, I do circa 20k miles a year with the odd track day so fast road setup would be preferable.
