Yeh i would make sure to have the yellow chromate up to the right temp first. Then after lightly drawing off the excess water with the edge of a shop towel i actually let mine dry for two days before i touch it at all.

Massive Update
Yes, updates. Many many updates and long overdue. There’s so much here I’ll probably let the pictures do the talking, but where I have helpful pointers I’ll mention them.
FRONT SUSPENSION
New ball joints in front control arm
M3 ABS ring gear (left, vs standard E30 on Right) zinc’d and installed on new front hubs
New shocks, freshly powder coated strut housings, some oil for lightly lubricating the inside (Korman said a light coating inside helps with anti-rust, but it isnt required like with factory ones)
New dust cover for the back of the bearing. Tapped on easily with a runner mallet and one of the press fittings from the bearing kit.
Time to reconnect the lower knuckle.I had them powder coated separately, left the facing sides bare but they got blasted clean.
Front brake backing plate
Time for these guys
They went on really easily. No need for a special tool. Literally pressed them on with my hand, then took a block of wood and rubber mallet to tap them the rest of the way down. Only had to get them to where the nut will thread, then you can tighen down the nut to get it all the way on. I’m waiting to torque the nuts down until the car is on its wheels.
Helloo
REAR SUSPENSION
Rear subframe mounts
Pressed in by hand. No tools needed. Just Teflon grease.
Layout
Shiny exhaust brackets
Professional help
Lots of Loctite
Rear Shocks
Spring Pads
Freshly powder coated brake shields
Parking Brake passthrough
OOOOoooo
ABS sensors - this got much more complicated than it should have. My avatar says “DO NOT OVERTIGHTEN” for a reason….
So i was putting them on, easy enough, put on the replated bolts, looking good, tighten, tighten, tighten, SNAP.. Bolt brakes off in the rear trailing arm. Great. So, out comes the drill. Drill Drill Drill Drilll. Then….
I had been meaning to buy a tap and die kit anyways…
Cleaned out and tapped
Victory.
Cleaned out the hubs. Cleaned up nicely.
Pressing on with the bearing tool.
Brake lines on
Re-whitening some white plastic bits - go on the front strut tubes, rear subframe, in the engine bay, etc, so i’ll just leave this here
Halfshaft to diff hardware
Diff bolt. Had to scrub off all the modern anti-corrosive with acid. Worth it though
Now last time i put the halfshafts back in, it involved a wooden block and a mallet. Not so this time. I did some research and found a resource that said the BMW tool for halfshaft installation is $500. Aaaaand there’s a Ford installer that does the same thing for the M3 (same pitch threads) for $10 on ebay: https://www.ebay.com/itm/Ford-Front-...72.m2749.l2649
Worth it. Much cleaner way to put these things back in. Super easy.
The other side was so clean it slid right in with minimal force. No tool needed.
Dont have all the diff to halfshaft bolts on yet because i replaced 8 of them that were partly stripped. Still, it was time...
More fresh PC
Lots of fiddling with the jack, later, and...
Brake lines connected
ABS sensor lines
Time for these guys
And the upper spring pads
Rear springs
The H&Rs were short enough that i didnt need to use a spring compressor to get them in.
Underbody line routing
FRONT BUMPER
Old brackets vs new brackets & replated hardware
New front bumper bolts. I’ve heard some people say these are NLA. They arent. They’re just on the wrong place in the OEM parts diagram.
SEATS
Seat Shocks
Replaced the uppers and lowers.
Keep the little caps that go over the retaining rings. Couldnt find them anywhere so I re-sprayed mine
Back together and the recline actually works now! It used to just free fall. New shocks are a huge improvement.
ENGINE BAY
Cleaned up the charcoal canister
All new hosing, re-used the pressure control valve (is NLA)
Installed
More fasteners from Belmetric
HVAC line mount
HALF SHAFTS
Inner
Cleaned up
OUTER
Soaked overnight in mineral spirits to remove the grease
Next Day
Lots of brake cleaner, brushing, dumping out grease, etc. until it came out clean.
New Grease - used about a tub and half between all four u-joints
Back together
New Boot on - the small inner clips on these guys were a pain. Getting the boots to go on while wearing a crimp clamp was impossible, and putting the crimp clamp on first then pulling it up over the lower end of the boot was just as impossible. I figured it out using some screw clamps (the same ones that GKN sent with their rebuild kit) with green loctite. The clamps can be found easily at BelMetric. Anyways….
Use included bolts to align
C-clamp back on
Back together - missed some steps in the pic (outer boots for instance) because this is seriously messy work and taking pics does not go well with it. There are a lot of tutorials around though. Still missing the inner clamps i mentioned in the pic below
Here was the solution. I used these for both inner and outer,
OTHER
Joined the filler neck to the gas tank
New gasket in the fuel tank cap, cleaned up the outside with mineral spirits and boiled linseed oil
Crossover pipe fittings had some surface rust left from the cleaning/paining. Some mineral spirits before the new pipe went on took care of it. Plated the crossover pipe as well.
Re-Plated the bolts for the hood catch
Minor, but this was a big win. The original speed nut that held on the coolant overflow tank was split. I looked everywhere for a new replacement, but the ones BMW makes in this size dont have nearly enough room between the two sides. The two inner sides basically touch in the new ones, and the application requires 2-3mm of a gap.
Broken original in middle, new replacement on left (not thick enough), one on the right is thick enough but is the wrong size
I was able to rig up the thick one that was the wrong size (took a smaller bolt) as a temporary fix, but I still needed a real fix. Sooo i went around the junk yard one Saturday morning pulling speed nuts off of various 80s-90s cars. I acid stripped them, polished them, plated them, and came up with - the replacement….
Now here’s on that i bet a lot of guys will like. The rear window latches started out black, but they whiten over time, and are very expensive to replace (if you can find them). I started out trying back to black, degreaser, and about 10 other cleaners and only succeeded in getting this far...
Then i went for, you guessed it. Mineral spirits - boiled linseed oil (I let the oil sit on the rubber overnight. It soaks into the pores), and….
Underside shield
Some plastic attachments routing the lines on the engine that go to the oil filter housing
BRAKES
Mineral Spirits, followed by Boiled Linseed Oil did wonders for this ABS cover….
ABS Pump back in.
New rubber feet.
Brake lines
Cleaned up one at a time and reinstalled
ENGINE AND TRANSMISSION
Cleaned up the camshaft and crankshaft position sensors
New wire gathering loom
Ready. Not yet fully installed with the backing plate. Need to get trans on the motor first
And speaking of the motor. It has been on the motor stand for way too long. Since June 2015. About time we take it off before it hits 3 years...
Flywheel and clutch going on this weekend. Might fit the trans as well.
Before that though, i need to get a few things on so that i can put the back of the car on ramps, use the engine hoist to pick up the nose of the car, slide the motor and trans assembly under, and lower the car back down. This means, parking brakes.
All new stuff, except the lower mechanisms which were replated and are indistinguishable from the new stuff.
I used new shoe adjusters. The old ones replated fine except for the big conical piece. It was pitted from years of brake dust, so I got new ones from BMW.
Knock around a bit and….
Then brake rotors (no calipers yet, just need the parking brakes to hold the wheels still on the ramp to act as a pivot point)
That has not been seen in my garage for a while.
Bit of wheel gap?

4 Years in... Rebuilding an E30 M3. I finished college faster...

Thanks and good question. The underside of the car was in great shape aside from a little dirt here and there. I was going to have it sprayed black, but my body shop pointed out that they see a lot of restorations where black undercarriage spray is used to hide issues like rust, damage, etc. So I left it original to show that there aren’t any issues with the structure of the car, and pressure washed it as much as I could without cutting into the underbody material. Parts of this restoration have been a trade off between originality and perfection - on the underbody I went with originality. I may go after the underside with a steam cleaner before it’s done
I see there are a couple broken links and pics out of order. I’ll fix it later. Tried to edit from Tapatalk, but the update is so big that trying to edit it crashes the app.

Outstanding. Total bling part porn overload. Speechless
Then you ruined it by fat fingering one of the picture links. You deprived us of ONE halfshaft photo! The shame must be unbearable
kidding of course. Made my day this postI BUY/SELL REFURBISHED CM5907s & CM5908s
HOWTOs:
DB vert plastic bumpers
OEM Keys
MTech1 docs
88 ix Lach/Card
91 ic Calypso 3.1
86 Cosmo 2.7
OEM+ or bust!
reelizmpro: I will always be an e30 guy.. I still do all of my own labor
TrentW: There's just something so right about a well-built M20 in an E30
e30m3s54turbo: I save my money for tuner parts.

Yeah steam cleaning sounds good but I recommend a clear rust proofing coat. This way you’ll be able to show the originality of the car.

I'm actually thinking about fabbing up a full underbody shield a-la the M1 to keep everything clean. I'd have to have a way for the exhaust and transmission to vent since its a front-engined car, but i could keep things from getting dirty and improve the aerodynamics. Maybe i could use some roles of pre-preg carbon fiber...ok lets get the car done first before we start down that rabbit hole.

Good thought. Not that this car will ever see salt, or rain, or anything that could cause rust. The camera flash also makes the underside look way dirtier than it is.

I don’t think you need a full underbody shield but that’s up to you. It looks great the way that it is. It looks amazing. Keep up the good work.

Not on r3v much these days... but what a satisfying update. I remember when this thread started and I would of never imagined it would become what it has. You are doing what I wish I had the time and money to do on mine, and I'm glad to be apart of the ride. I feel blue-balled that you teased the engine on the hoist without putting it in, though. (hehe)
This thing will be a piece of art when finished.Current:
1989 325i
1988 M3
1987 325ic
Past:
2001 330ci
2001 M3

Thanks. Waiting on some spacers for the pressure plate bolts before I can mate up the transmission and the engine. Then i'll be installing the whole thing from underneath (lifting up the nose and lowering it onto the engine)
Here's the Evolution Lightweight Flywheel
Clutch
Pressure plate needs spacers though. It didnt have spacers when i took it off because PO used incorrect pressure plate bolts. The smaller ones work, but apparently the spacers and larger bolts (called for by OEM specs) can maintain bolt load more consistently over time. I ordered the correct bolts, but without the spacers (and it didnt work, as you can see below). Spacers are on order. hope to get them this week.
OEM spec diagram, with the sleeves in the wrong spot. Should be between bolt head and outside of pressure plate
In the meantime, rear brake lines went on...
And i got a new sensor holdy thingy
