Lowering module
The often quoted reassuring “Full Front & Rear '4' Wheel Alignment” is only Toe - “Directional” adjustment (new car industry's best kept secret).
Then being told because of broad alignment parameters “is within factory specs”.
It's all to do with cost cutting and the ever increasing speed of OEM assembly lines.
No front Camber and Caster, no rear Camber to adjust tire contact angles spread load more evenly. Excess edge load can also lead to ruptured side walls and rim damage.
We saw the need therefore to fix it right the 1st. time. To resolve costly, premature, edge tire wear issues – to cater for other then showroom height conditions !
Day to day commuting encountering high cambered roads, wheel squat through load carrying or lowering, fitting wide profile tires, curb knocks etc.
FOR THE W213 AMG WE MNF. A “TOTAL SYSTEM” WHEN IT COMES TO FRONT & REAR ALIGNMENT (in fact every Mercedes Benz Model 1968 to 2021)

They're high strength forged alloy same as OEM. Not soft extruded aluminum or welded, fabricated.
Do point out that the Mercedes Benz W213 AMG rear lower arm mounts are slotted. You can purchase a inaccurate one only offset position Camber plate. Providing minuscule 3mm (1/8”) Camber change.
We saw the need and designed created the #502326-1K kit (see attached instruction sheet) to provide '4' times the adjustment range (Pos or Neg) and to be accurate precise – single wrench adjustable !
Also includes extra Toe to compensate. Bush extraction tool included so no need for arm removal.

Invented patented the single wrench “bush adjustment system”. The quickest, biggest all positional “strut adjustment” system and for “wishbone suspensions” the adjustable ball joint, which is now the industry standard!
Yes along the way mistakes are made but Elon Musk echoed Ferdinand Porsche “If a mistake not made.... you are not really trying”
It’s same with the OEM industry it’s all about “constant ongoing development”.
Anything & Everything can be improved, Kevin.

The Best of Mercedes & AMG
But where confident the current generation, no other brand comes close re Quickest, Biggest, Strongest adjustment systems.
ESPECIALLY WHEN OWNERS UNDERSTAND THE ISSUE:
Replacing the “Front Upper Wishbones” with welded, fabricated arms”
VERSUS THE 4 KMAC OPTIONS LISTED ABOVE (#29)
1. Camber Adj. Bushes $295
2. Camber and Caster Adj. Bushes $480.
3. Wishbone Camber & Caster Adj. Bushes $380
4. Wishbone complete arms (Forged alloy) Camber & Caster Adj. $795
As set out experience of 57 years solely in aftermarket suspension design - “Replacing the Safety, Security of the Mercedes factory (highly critical front upper wishbone) arms with welded, fabricated arms for us is not a option.
Do point out by far most popular kit is #1. (503416-1G) – Lower arm “Camber” adj. Bushes (fit without arm removal, single wrench adjustable, retains tire to outer fender clearance).
While #3 (503316-2J) upper inner wishbone Camber & Caster adj. Bushes RETAINS THE SAFETY, SECURITY OF THE MERCEDES FACTORY ARMS.
#4 (503316-3P) Complete upper wishbone arms Camber & Caster adj. FEATURE HI STRENGTH FORGED ALLOY SAME AS OEM.
Best Regards Kevin

There is only one way get correct camber when lowered
As above, did one's best to set out that currently there are '4' alternatives !
All with the security of not replacing a key / critical OEM suspension component - “Front upper wishbones” with welded / fabricated arms.
Most popular #1 503416-1G (also at $295 both sides the cheapest). Plus the security of retaining the OEM hi strength forged alloy arms and can install “without the need for arm removal”
