Rear AAD Suspension set up question...

[Old Mopar Guy]

Alright. So I’m out of there. I was there for 5 hrs. he charged me for 3. Yes, 150.00/hr as he advised me from the start. Total 488.00. Below are my before and after rear readings in addition to the front. I haven’t played with it as I had to get right to work. I was looking for as close and flat as he could get it bearing in mind a few of the thoughts you guys suggested here and the other place. Thoughts pls. Thanks.

Here for 3 hrs and still not done with just the rear. Although they’ve never done one I had faith. I’m loosing that faith pretty quickly at this point. I’ve already told them to forget the front alignment and just get the rear done as I’ve got to get to work. Cant wait to hear what my bill is going to be. 🤮

Front is easy, have him slam the camber and caster tabs, in check it. Anywhere near the specified camber will work. Then simply do the toe, which takes ten minutes in my garage anyway!

I think you will like it.
I really like the front for the street, your tires will last forever.

That really isn't bad for a first timer and a 5hr crack. The numbers look pretty good overall. I personally would like to keep toe close to 0.10 and if you want to get closer to 0.0 camber go down 1 tab on each side...so if you have 7's go to 6's. Each tab is ~0.20 degrees adjustment or thereabouts...but all that is just being picky. On a good hard launch that should plant plenty flat for you.

what tabs did you end up using? What is put in new, was it 5?

 

[vortecd]

What is stock for rear camber or what has anyone seen? I have seen some challengers that the wheels are farther then flat then others

 

[Old Mopar Guy]

I kept a count of all the tabs I dropped off and their values. Looks like they removed 2 “0” mm and 3 “2” mm tabs and replaced them with 2 “6”mm and 3 “4” mm tabs. As supplied from AAD I asked for stock length arms and compared their length to the factory parts I removed to confirm. I’m going to get the car on the Quick Jacks this weekend just to check everything, torque values, etc.
What concerns me is that it seems these tabs would have to be used in pairs for each arm, so how is it they R&R’d 5?

Good luck finding a tire alignment shop that has ever even heard of these. Everybody in Hellcat Drag World has, but in the big wheel alignment picture nationally….. 🙄. I used a Big O Tire shop where I do all my other business. They didn’t charge me anything to pull the car onto the rack and get the numbers. There was no charge because they didn’t “do” an alignment. Then I went home and changed the tabs myself. Two more trips (3 total) to the rack and it was done. Didn’t cost nothing. I know this was definitely an exception. They just dug my car a lot 😁

IIRC the rear arms take 1 each and so do the toe rods if you did those. So 6 total for all 6 arms (trailing arms are fixed length - they don't count)

Likely this means your arms not only front to rear but side to side are all a different size. That can happen but isn't very typical. Usually the upper F/R arms are the same length per side. So your L will have matching tabs and so will your R. Typically. Each car is different.

What matters is that you verify what tab is in each armand write that down for your records so you know what to change each one to...and which ones to order if you need more.

I guess I should mention if I didn’t already no front end work was done with AAD parts. All oem.

 

[Old Mopar Guy]

I hit each tab with permanent marker so I can easily record their value while on the car. Hopefully the markings are still there. I will see over the weekend when I have the car up.

Well at least they tightened the two nuts down on the control arms. My alignment shop didn't and right around 140 things got squirrely

Exactly why I’m going to get under there this weekend.

I did my own install but the two nuts that hold the tabs in were not tightened back down.
Report back let us know how you like these things

Best bet for saving alignment money, this is what I have and cannot be more happy…

Looking at my arms it may be 2mm that come installed based on AAD chart?

Based on speedys video it looks like the 0 is the starting point on the toe arms. I would think the upper arms would have the same tabs for the 2 per side

 

[Old Mopar Guy]

Yea, I looked at that too.

 

[Old Mopar Guy]

@vortecd under the car today. +4mm on either top arm, and +.5mm on the longest bottom arm. P/s pics first:


On the d/s both upper arms took +6mm with the longest lower are taking another + .5mm

 

[fubar569]

That's less than my car took. I needed 6's and 7's.

Glad to see the toe rods needed minimal tweaking too. They must be pretty close from AAD.
