Camber & Toe on 43 and 63
I purchased a 2023 GLC43 V6 and 2021 GLC 63 recently. I've read a lot about how the negative camber (like 2 degrees) and aggressive toe result in poor tire life in return for better handling. I'm thinking of getting some suspension work done that will moderate the negative camber and aggressive toe for better tire life and I'm willing to sacrifice some cornering. As it is, I'm sure I'm not utilizing the car's maximum corning ability, so it isn't really much of a sacrifice. What might be a more balanced camber....like negative .75 degrees? I don't know what the stock toe angle is, so I haven't a clue on what to change it to. Also looking for the parts to change-up both issues. What exactly should I be looking for in terms of hardware?
Thanks!
Thanks!

Yes today's models cost cutting and ever increasing speed of new car assembly lines front Camber (and Caster) along with rear Camber has been deleted.
Now the often quoted reassuring “Full Front & Rear ‘4’ Wheel Alignment” is only basic Toe “directional” adjustment.
Camber & Caster are fixed at one (showroom height) setting. Onus now back on owners to fund costly, premature tire replacement !
Yet essential - daily commuting and encountering high cambered roads with excess passenger side edge wear. Or inner edge wear both sides through extra passenger loads or lowering. Excess “outer edge” wear through spirited driving. No longer the ability to compensate for curb knock damage.
We saw the need therefore and manufacture “BOLT-ON” front and rear kits. Specially designed with bush extraction tools so no special tools required or the need for time consuming control arm removal.
Unique K-MAC patented design also allows precise single wrench - easily accessible adjustment. Ultimate direct on alignment rack UNDER LOAD.

Did you ever reduce the negative camber? I'm on the fence about installing some of the k-mac bushing to reduce the negative camber but can't seem to find much about the results and what they set the camber to.

I have had MB do both our GLC43 and ML63 for a 4 wheel alignment and it’s been perfect. 15,000km on the PZero’s on the GLC and it has even wear. They get all the heights perfectly correct on all 4 corners. It’s not expensive either under $200.

I'm strongly leaning towards the k-mac caster/camber kit to reduce the caster as much as possible and increase camber to just barely negative, and go from there.

What year is your GLC43, and lhd or rhd? My 2017 GLC43 was aligned twice at the dealer, it's not an alignment issue, some model/year/tire size/l vs rhd combinations are worse than others it seems from the threads on here. Mine is a 2017 RHD w/ 21's and it's terrible. I have to dismount and swap the front tires inside to out to wear the other edge at about 10k km and I can get about 20km or 3 years, but even the center of the tire wears prematurely from the crabbing/horrible caster & camber. The stock camber is at -2 and change and caster is +7 and change. That combined with RHD and 21s is causing terrible premature tire wear, mainly on edges. Also, if I turn all the way left or right, the wheel won't return to center, from the positive caster, and the car crabs terribly when wet or on snow or dirt. MB released a updated steering knuckle to address the crabbing (not sure how that worked) on non-ABC GLCs, but all our 43s and 63s are ABC

I have Pirelli PZero’s on it , they would have about 12,000km on them now.
It will only crab a little on a hard turns in the driveway. I don’t have any specs on what they did sorry.
255/40/21 on the front and 285/35/21 on the rear. 12mm wheel spacer on the rear and 10mm on the front to push them out a bit.

It’s a 2018 GLC43 RHD. With 21” wheels. I actually just check the wear on them last week when I washed it. They are wearing really well and even.
