Rear camber problems

Get your camber set, then worry about toe. Makes life much easier.

You should be able to get way more negative camber. Verify that the camber arm bolt to the subframe is completely inboard in the slot and doesn't move out when torqued.

The alignment tech showed me the bolt and it looked all the way inboard. This is frustrating. I looked at the list of mods that I did in the rear to see if something could have impacted the camber. The BMR control arm bearings, i dont think so. Neither the ford performance toe bearing.

I'm thinking about the the BMR CB005, the level 2 cradle lockout, is that possible to mess up? Like put the front bushing cup on the rear and the rear to the front? https://www.bmrsuspension.com/siteart/install/CB005.pdf

I am tempted to order the SPC camber arms or the AAD performance camber arms. Any experience with the 2?

SPC:
up to -2 rear camber
bonded bushings
a little more expensive
indestructible

AAD:
up to -3 rear camber
inboard poly bushing (maybe need to grease after sometime, a lot of rain/dirt here)
outboard bearing
cheaper
not sure if anyone has had failures? Seems like other brands with threaded rod can snap, but I don't see much talk about these

I've had AAD rear camber arms since 2022 and have autocrossed with them, daily driven, and four track days. I think they are by far the best option for S550's. I think you see less of them because 1) they are a late comer to the S550 game like myself and 2) they were originally focused on the Mopar market. They do not place a threaded adjuster or rod end in bending and they have super quick and easy repeatable adjustments (each tab measured about 0.15* camber change for me).

Thank you for the reply. I had spoke with AAD and ordered them like 1 minute ago lol I ran it through ChatGPT deep research and it didn't find any failures with their design like I've seen on others.

I just arrived in NYC after a canceled flight gave me an unexpected stay in south florida. and then delays getting to NYC lol the camber plates and AAD camber arms I had ordered are here, but I bought a second hand camber plates on ebay that appear 100% new. It came with the 4 bearing spacers (2 for 14mm shaft and 2 for 16mm shaft). One of the 16mm spacers are loose in the bearing. ChatGPT says that my ford FR3 struts are 14mm shaft so I should be good. Can anyone else confirm the ChatGPT info?

Maybe AAD made a design change, but mine are all sphericals in the arm. I don't remember swapping any bushings on mine. Maybe I did, it's been 4 years since I threw mine in.

They have been awesome. I would highly recommend them to anyone. You made a good call.

I am talking about the BMR camber plates and the bearing spacers for the front struts.

My comment was directed at your choice of rear camber arms.

My AAD rear camber arms are inboard poly bushings and outboard their proprietary spheriflex or whatever they call them rebuildable ball/spherical joints. Mine were purchased in spring of 2022.

Nothing has changed with the AAD camber arms. I'm talking about the BMR camber plates. I have 2x 14mm bearing spacers and 2x 16mm bearing spacers. One of the 16mm bearing spacers have a lot of play in the strut mount. But I think the Ford FR3 track struts are 14mm so I should be good to go. Seems like the 16mm is only for coilovers

I got everything installed and aligned. The AAD arms came with the most negative chip and if I had to do it again, I would start with the mid-setting chip, set the toe, and choose the next chip.

I was helping the alignment tech, but ran out of time and had to go to work. So I'll tweak the right rear another weekend.

Front Left: -2.18 camber, 6.38 caster, 0.05 toe
Front Right: -2.28 camber, 6.68, 0.05 toe

Rear Left: -1.7 camber, 0.15 toe
Rear Right: -2 camber, 0.15 toe (I'm going to go a little bit more positive when I have time)

Probably run my TW300 tires until they are good and worn, and look for TW200 (this will be HARD in Colombia, probably need to import)

The AAD arms are nice, but take extra time to get it right.
With the lockouts to "street/drag" the most negative was -0.8, so the most positive should be more than enough to get positive camber on the most lowered cars.

With the lockouts to "track" the most negative was -3, but we didn't align the toe with this setting so it would vary. The most positive can probably get to -0.1

The BMR camber plates still have some more negative camber up front.
I am happy with the both products, but keep in mind, the AAD arms do take extra time. And be sure that your alignment tech uses glasses because he bent 2 chips and I had to straighten them out with a hammer lol that's why I jumped in and started helping him.
