Actual alignment specs from BRZ

[taosracer]

I saw the alignment instructions from the manual, posted on STIS in case you're interested :

Would http://www.subarupartsforyou.com/cp_...p?partid=15252 help as well? Part # 20540AA100

I'm also wondering about how to adjust the alignment to make the car easier to drive in a straight line on the highway. Although I'm getting more used to it, I feel like I still have to constantly make corrections to the steering (only on the highway!).

Thanks, but it looks like this is still not available to the public.

I do have the Scion version downloaded to a pdf, which is what I quoted from and we had at the shop.

If you find significant rear camber adjustability, please post up!

No that is the same bolt that's already in the lower position. Camber is adjusted at the top concentric bolt. The bottom is just a regular one.

To answer your second question, no an alignment will not make it easier. Sounds like you just need to get used to a car that actually gives you steering feedback.

This is best I can do with copy/paste. You have to buy a subscription to gain access.

CAUTION:
To ensure proper functioning of the brake system, be sure to perform the neutral position setting of the VSC (VDC) sensor as initialization after alignment adjustment or removal/replacement of suspension or underbody parts. (Refer to )
1. Tire inspection (Refer to )
2. Vehicle height inspection (Refer to )
3. Side slip inspection
(1) Check the side slip using a side slip tester.
Standard value : 0±5 mm {0±0.20 in} (per 1 m {3.3 ft})
CAUTION:
·Enter onto the side slip tester in the straight ahead position at a speed equal to or less than the walking speed (4 km/h {2.5 MPH}), and perform the inspection while in neutral.
·Do not depress the brake pedal on the tester.
·Do not turn the steering wheel on the tester.
(2) If it is out of standard value, check the wheel alignment.
4. Toe-in inspection
(1) Bounce the vehicle to stabilize it.
(2) Move the vehicle straight 5 m {16.4 ft} forward by manually pushing it.
CAUTION:
If the vehicle has been moved backward, be sure to move it forward by the same distance.

(3) Adjust the height of the toe-in gauge pointer so that it is at the same height as the center of the rear wheel axis, and set it behind the tire.

*b

Dimension B

Front side of vehicle
(4) Place a tread center mark on the back of both rear tires, and measure the distance between the marks (dimension B).
(5) Move the vehicle forward by pushing it slowly to rotate the rear wheels 180°.
CAUTION:
Be sure not to rotate the tires more than 180°. If the wheels have been over-rotated, repeat from the setting up of the toe-in gauge.

(6) Measure the distance between the marks at the front of the tires (dimension A).

(7) Calculate the toe-in.
Standard value : 2±3mm {0.08±0.12in}
NOTE:
Toe-in = Dimension B - Dimension A

5. Toe-in adjustment
(1) Loosen the toe adjust cam nut.
(2) When adjusting the toe-in of the left and right wheels at the same time, adjust the toe-in by turning the toe adjust plate No. 2.
Standard value : 2±3mm {0.08±0.12in}
NOTE:
When the left and right toe adjust plate No.2 are turned by one graduation, the toe will change approx. 4.0 mm {0.16 in}.
(3) Tighten the toe adjust cam nut.

Standard value:
Tightening torque=100N·m { 1020kgf·cm}
{73.8ft·lbf}
6. Camber inspection
(1) Lift up the vehicle on a level surface.
(2) Set the wheel alignment gauge. (Refer to )
(3) Calibrate the wheel alignment gauge. (Refer to )
(4) Check the camber.
Standard value

Camber

0°00’±45’
CAUTION:
·Perform the inspection while the vehicle is at curb weight (with the spare tire, jack, and service tools loaded and with a full fuel tank).
·The limit of difference between the left and right camber values is 45’.
·Remove foreign matter from the axle hub end surface before performing the inspection.
(5) Remove the wheel alignment gauge.

7. Rear suspension inspection
(1) Inspection of rear suspension member
(a) Check the distance between the center of rear suspension arm ASSY No. 2 LH and RH mounting bolts.
Standard value : 445.8±3mm {17.55±0.12in}
NOTE:
If it is out of standard value, replace with a new rear suspension member.

(2) Inspection of rear suspension arm ASSY No. 2
(a) Check the distance between the center of rear suspension arm ASSY No. 2 mounting bolts.
Standard value : 449.9±2mm {17.71±0.08in}
NOTE:
If it is out of standard value, replace with a new rear suspension arm ASSY No. 2.
(3) Inspection and adjustment of toe-in and camber
(a) Check the toe-in and camber, and if they are out of standard value, adjust them with the play in the mounting portion of the rear suspension member or that of the upper control arm and rear suspension arm.
8. Confirmation of front tires in the straight-ahead position
9. Mid point setting of the VSC (VDC) sensor (Refer to )
10. Settings during part removal/installation (Refer to )

Hers is the key part for adustment:

Check the toe-in and camber, and if they are out of standard value, adjust them with the play in the mounting portion of the rear suspension member or that of the upper control arm and rear suspension arm.

All of those measurements are very peculiar, especially the front caster. They should not be drastically different like that. The rear tow is completely screwy too, as it would make the car want to crab down the road.

How confident are you of the technician, the rack used and the specs you got from it.

Yes, they will work with both stock struts and coilovers.

Hope to have them available very soon. If you like, send me a PM and I'll send you a note when they're in.

I agree, these numbers are a little screwy. Caster and SAI especially.

that exactly what we thought...Tech...friend...been doing performance stuff for a while now... that and he was my co-driver this past weekend...

Anyway you clipped the front right wheel somehow?

[Racecomp Engineering]

Just got mine aligned with WL com-c hats and oem camber bolts.

-2.3 front camber and in the rear -2.25 rear left and a awful -2.75 rear right. Cant wait for the WL kit to reel that back in some.

This car is lowered with our proto springs.

Caster is SICK. The WL com-c hats ON THIS chassis gives upwards of .80 caster gain which is amazing. camber gain is about .75 for the whitelines too.

So yes we will offer a BRZ intro kit. Springs, bolts and hats.

[EMguy]

Can anyone clarify the proper location and part number for the OEM camber bolt?

This page tells me to use 901000394 in the upper attachment point. Is this right?

[uspspro]

I know generally more caster is better, but that's more caster than I've had on any other car. Is there a point where it is too much?

Is caster otherwise adjustable?

Is all that negative camber in the rear coming from just the lowering springs?
