I'm currently on -3.1F/-2.5R/0Toe which provides a very neutral feel - 255/40/17 RS3. Aligned by Eric@

Don't have experience with aero setups, but for non-aero, -3.0F/-2.0R/0Toe is a good starting point.
Note: You will not be able to achieve -3.0F with stock strut and camber bolts alone. If you have slotted coils + camber bolts you'll max out around -3.0F.
(This is not recommended; however, there are people who run this to stay in certain class for 86cup)
Contact @
Elite Performance or @
The Racers Line and i'm sure they can help with further details.
