KW spring install - ABS, DCS lights are now all ON - Help


I've done some searching but haven't found anyone having my identical issue.
I'll lay out the timeline and changes below.

First off my car is a 2011 E90 with ZCP and DCT.

Fri - 2/10 - KW sleeve over kit installed, low but not the lowest setting. Car rides well but needs an alignment BAD.
NO LIGHTS or errors.

Sat - 2/11 - Alignment done at local shop. Specs are not all within BMW spec on the Hunter machine but I was ok with that because i was going to get GC camber plates.

Front L = -1.4 camber
Front R = -2.0 camber
Both heights the same but i couldn't get anymore out of the left.
Rear L = -2.5
Rear R = -2.7
Camber seemed fine but could get no additional toe to bring within spec.

2/14 - driving to work the following lights come on. All are in AMBER, not Red.
ABS, DSC and Brake light are all on. Car also shifts from 1st to 2nd in manual mode at 3k rpm like it was in D mode. Very odd.

2/17 - Today. Take it back to the shop that installed the springs. They ran the codes and find the Right rear speed sensor is erroring. We clean the gunk off and the lights are all still ON.
They think that the alignment is so out of spec that the computer is malfunctioning.

Does this make sense to anyone?

Do i need to get the full alignment spec outta the car to really troubleshoot this? Seems to me that people who track all the time, and have crazy alignment specs would see this...if it was due to that.

Hope this all makes sense. Thanks
