MS3 alignment spec help

[MTBjunkie00]

Took the car in for new rims/tires and an alignment before winter. The tires/steering wheel shimmy very hard now above 65 (doesn't go away at higher speeds and isn't present at lower speeds).

The car used to have a slight left pull and pulls hard to the right now. Alignment sheet from the shop here. I've searched around the forum, but couldn't find a definitive alignment spec for an '09 speed 3.

Any help on my situation or official spec sheets would be greatly appreciated. Thanks all.

BTW, I switched from a 215/45/18 to a 235/40/18 if that helps at all. Stock suspension.

The shimmy is normally caused by a wheel or wheels that are out of balance. So take your car back and have the tire shop that put the new rubber on your car balance them again.

Here are the factory MS3 alignment settings:

Front Suspension Wheel Alignment (unloaded)

Total Toe-in
Tire .08" [tolerance +/- .15"]
Rim Inner .04" +/- .12"
Degree 0 degree 11 arcminutes +/- 11 arc minutes

Caster angle
3 degrees 8 arcminutes [tolerance +/- 1 degree]

Camber Angle
57 arcminutes [tolerance +/- 1 degree]

Steering Access Inclination
14 degrees 21 arcminutes (reference)

Maximum Steering Angle
Inner 36 degrees
Outer 30 degrees 12 arcminutes

Rear Suspension Wheel Alignment (unloaded)

Total Toe In
Tire .08" [tolerance +/- .15"]
Rim Inner .04" +/- .12"
degree 11 arcminutes +/- 11 arcminutes

Camber angle
-1 degree 42 arcminutes [tolerance +/- 1 degree]

Thrust Angle
0 degrees [tolerance +/- 48 arcminutes]

fyi 1 degree = 60 arcminutes

For what it is worth, the MS3 is known to have a slight pull towards whichever side the transmission sits on (I can't remember right now, too early in the morning on my day off, LOL). It needs to be taken into account... But yeah, I understand your feeling. I have to have my steering wheel turned to 10 o'clock in order to go straight down the road!
