After getting the winter setup installed and KW adjusted down I got an alignment done (lifetime at Firestone) and the results weren't great regarding camber. The E70 lacks useful adjustment in the rear and has no camber adjustment up front, not ideal when you are lowering a vehicle.

Previously I installed Meyle HD upper wishbones with a camber adjustment but never adjusted them. I also snagged some SPC upper trailing control arms for the rear and a magnetic camber gauge so I could crudely DIY this and see the improvement.

Here are my "before" at-home measurements:

FL -2
FR -1.6
RL - 4.2
RR -4.1

"After" at home measurements:
FL -.6
FR -.5
RL -1.75
RR -2.2

"After" according to Firestone:


I asked for them to set total F/R toe to .02 instead of .2 and they weren't able to oblige. "We got as close as we could." But I've seen many posts of E70s getting the toe down to .02 so I know it's possible. I might go to another, more competent Firestone ....if such thing exists.

Precise science! Garage floor level?


...kinda


SPC control arms



Here is a look down at the top of the Meyle HD upper wishbones on the front. This is there "normal" position before.


...and after with + camber maxed out. I couldn't find info online with their adjustment range but I think it is +/- 1 degree.


I also installed a new K&N filter, hydro sock, and cleaned the MAF. Performance greatly improved after this. I think I over-oiled my K&N previously and Colorado grime was clogging it up. I now have a significant performance gain, like >30% power. Whoops! Once I get ISTA properly installed I will reset the MAF and injector mean as well. I've never done this even with my various intake setups.



Local LKQ had a couple E70s so I grabbed a couple trim pieces I needed to replace broken ones and I also stumbled upon this tray/insert for the center console.


Living a life of true luxury ...with my Carmex in a secure spot. Colorado shit.



With temps dropping my battery was showing weakness. A bit annoying as I was trying to adjust my rear ride height via air suspension and sensors and the battery died, adding insult to injury my fancy-pants Schumacher INC-700a charger isn't powering up so I was forced to use my mobile power station / car jumper but it wasn't allowing the jump and stating the battery was in a protection mode. I was able to recover the battery over night with my trickle charger but the real solution was a new battery.

Current battery was installed shortly before I bought the vehicle ~5 years and 55k miles ago. It was an AC Delco 49AGM. 95AH 900CCA. It aside from the drop in performance with ambient temps around or below freezing it has served me well.

Replacement is Super Start AGM. 105AH, 950 CCA


Turns out when the last battery was installed it was never registered to the vehicle so the X5 thought it has a 105AH and it really had a 95AH. That has been corrected.
