Alignment help needed with modified suspension!

[zmon1300]

Hi all,

I have revamped the suspension on my 04 boxster for track duty and light summer backroad driving.


Here is what I installed on the car.

ECS Tuning Coilovers (camber plates on the top, adjustable dampening from top)
New front control arms with Powerflex purple bushings with maximum caster sleeves
SPL Adjustable Sway bar end links Front and Rear
Eibach Front sway bar (non adjustable) 26mm
Eibach Rear sway bar (3-way adjustable, tubular) 22mm

Attached are some screenshots of the parts.


Looking for the best alignment specs for this car to make it handle like a gt3 or rs.
Hoping to do more track driving this year but also driving this in the summer as well.
Not looking for jaw wrenching stiffness if that helps!



I have not found many posts with good alignment specs thats agreed upon. All I know is to max out the negative camber on the front, subtract one degree from front camber for the rear camber, and zero out the toe.

Is that truly the best setup? Looking for feedback. What about Caster?

caster only has any effect on the front - it impacts turn-in (think shopping cart wheels) so playing with caster on the back doesn't do anything. note that playing with caster on the front will move the wheel in the wheel well such that it might look a bit funny and could cause clearance issues (esp when turning) if you are running max rubber.

i don't have a value for you as i kept mine stock, but check on rennlist as the 996 guys (esp gt3 folks) do play with it. here's a thread w some info ...
