The One to End It All

I am fairly certain the stock ABS system does not do any biasing so you could definitely just keep the stock valve to simplify things.

Pretty sure you’re correct. There is a stock “proportioning valve” on the main run to the rear line IIRC

All good input
In reality I have no idea if this system works or not. I have no reason to believe it doesn't work considering the AC was still functional.

Finished pulling the driveshaft. The CSB seemed to be new which is neat!

Wait...

Found some performance parts hiding in it! Offset CAB's!

Firewall sound deadening / heat shielding removed carefully. Not a single piece of messed up hardware. I keep waiting to find rust... Still no signs

That Bluetooth CSB

Engine bay cleaned up pretty nicely with some simple green and a pressure washer. I really wish the white cars didn't have yellow cosmoline. I would be tempted to not paint it but the yellow kills it so badly.

Yellow Cosmoline? What is that. Sorry, newb question.

Borrowed from the same factory they made mosin nagants at

Cosmoline is a sealant / rust proofing that was applied to engine bays of E30's during transport. For the short duration it was on for transport no discoloration is usually observed, and dealers were supposed to wipe it out of the engine bays and apparently there was even a bottle of mineral spirits shipped in the engine bay to do so. Most dealers did not, and after the vehicles start seeing heat and use the sealant yellows and hardens, becoming very difficult to remove.

Circa ~2005 BMW was still shipping cars covered in a heavy wax coating that was pressured washed off with high heat water.

I forgot how much fun stripping seam sealer was!

Not sure about e30s, but the “proportioning valve” on an e21 applies the same pressure to the front and rear up to a certain pressure, and then biases after that. The intent is that during light braking, the rears get activated to even out brake wear and keep rust off the rotor... er, drums.

It's uncomfortable how easily everything comes apart on this thing... Parking brake lines running into the chassis came out without even pulling

Tossing in riser bushings and new trailing arm bushings, rebuilding and painting the brake calipers, repainting everything, installing new brake lines, and putting it back in without a diff or axles (current ones lack grease, and diff is wrong for my application)

Progress, not engine bay though, which I'm waiting for some warmth from the elements before painting.

Refinishing the rear subframe is something I would like to do in the future. RTAB's, subframe bushings, powder coat the frame and the arms, and change the seals on the diff. I just need a place that the car can be up on stands for awhile.
