2009 Mazda 5 Sport.
I just paid a mechanic to install the KYB suspension parts from this list: https://www.mazdas247.com/forum/attachment.php?attachmentid=214666&d=1470238937
Went with gas-a-just for rear shocks. Added the SPS-67420 rear upper control arms and new front sway bar.
Had an alignment, asked that the rear camber be put at 0 to -0.5, that was done, but the car now shakes between 55 and 65 mph. I'd call it a moderate to heavy shake in the steering wheel.
My thought is that by taking the wheels on and off at least twice a weight was knocked loose and one of the wheels are no longer in balance. Then again, my current wheels are pretty worn on the inside, I've had them for 20,000 miles and the inside of my tires are normally bald by 27,000 miles (which is why I wanted the adjustable rear upper control arms). I'll get the tire balance checked tomorrow but in the meantime, how do these alignment specs look:
All are current measurements. Format = low range [actual] high range, all in degrees
Left front
Camber: 0.3 [-1.0] -1.7
Caster: 4.0 [2.5] 2.0
Toe: -0.09 [0.12] 0.28
Right front
Camber: -1.7 [-1.1] 0.3
Caster: 2.0 [2.7] 4.0
Toe: 0.28 [0.13] 0.28
Left rear
Camber: -0.3 [0.0] -2.3
Toe: 0.00 [0.11] 0.23
Right rear
Camber: -2.3 [-0.1] -0.3
Toe: 0.23 [0.05] 0.00
Front (for both)
Total toe: -0.18 [0.26] 0.55
Steer ahead: -0.05 [-0.01] 0.05
Rear (for both)
Total toe: 0.00 [0.16] 0.45
Thrust angle: -0.80 [0.03] 0.80
If you're wondering, total parts including rear adjustable upper control arms and sway bar for front was ~ $750. Suspension labor was $550. Alignment was ~ $100. So about $1,400 total, but the suspension feels great again and my tires should last at least twice as long.
