Is there a lot of wiring that will need to take place? Or is it mostly plug and play?

Not down that rabbit hole yet but some repinning and running some wires should do it.

Immense progress! in exchange for a sore body im sure

YoungCR

hot damn you guys had a serious wrenching party today.

DrLeadFoot

8 hours in so far! A couple snags but nothing major yet.

Trans crossmember bolts up to holes that weren't used before. Needed to run a tap through to clean them up.

Installed:

M5 steering box, swaybar, motor & trans.

Just bolted up the subframe, trans, pos. & neg. cables and starter power wire then called it for the day.

I'm feeling it a bit! Lol

Awesome!

Side note, thoughts on the MaxJax lift system? I've been looking into either that, or this: https://www.gregsmithequipment.com/Atlas-BP8000

I would have to notch my ceiling (104") to fit the Atlas lift (108"), but feel like it'd be a better long-term option. The MaxJax could be installed as-is and are portable.

It's my buddy's lift and he likes it a lot. It hasn't been able to hold us back on what we're throwing at it. 4 stars! Lol

Progress!

Front M5 brakes all buttoned up.

Rear: 540i diff and axles out. Passenger side M5 brake all buttoned up. Needed to notch out the m5 backing plate to make way for the caliper. Might be the air suspension that was different to the M5.

Diff out, m5 diff cleaned up and new pinion and output shaft seals installed.

Had a little window this AM to chip away. Relocated the ABS Precharge pump (I think that is what it's called) with an M5 bracket behind the front bumper and popped in the M5 plastic piece for the brake lines to run through and driver's side air intake hole.

Need to run the M5 brake lines to the pump. One line looks like I'll need to splice in a connector on the thicker line.

Only pic I took. 540i abs mount

Thanks!!! I hope it will work!!

A little here, a little there continues.

I had a little window this AM and got to working on the driver's side airbox area. The M5 cold air intake is now mounted behind the bumper.

ABS precharge pump lines are ran and tightened down.

Need to figure out exactly where the oil filter/PS reservoir bracket mounts. I'll get the air filter box in there and find the sweet spot.

Mike is going to finish the rear end tonight. M5: Diff, driver's side rear brake, axles, swaybar and driveshaft are on the list.

DrLeadFoot

M5 Diff, axles swaybar and brakes are in. Need to order new shifter bushings (one got lost in shipping) before we get the driveshaft installed. 540i auto shifter and pedal assembly are out.

Engine bay to-do:

- mount oil filter housing bracket to the strut tower and line up airbox mounting hole prior to drilling holes to use as a guide to where it goes.

- radiator & reservoir, hook up hoses, fan.

- install clutch line.

- bleed brakes/clutch.

- run M5 fuel lines

- install "new" servtronic solenoid & run wires to ECU.

- hook up power steering lines

- install passenger side exhaust manifolds

GOODNIGHT!
