Is POR-15 available in a spray can? What is the best method for doing suspension components at home?

Thanks,

Eric

Unfortunately - it's not available in a spray. It's damn durable though. I like Rustoleum satin black as a top coat for just about everything in the driveline/suspension.

Update...front seats are done. As athayer said, POR doesn't come in a spray can. Single use brush is the best way that I've found. I then top the POR 15 with POR chassis black paint. Although Chassis Black also doesn't come in a spray can, I've had good luck using a Preval sprayer (google Preval..can be picked up at the local home improvement big box).

Chuck,

Glad you gave those seats a fitting home. They look awesome!

Nice work, so far. Are you going with, euro bumpers?

Very nice! good job.

Devinder · Post by **Devinder** » Jan 28, 2011 9:41 PM

small detail -- those are not mtech springs. The fronts are 5.5 turns in your picture. Mtech springs are 6 turns. The rears have the same problem. Those are small OD non-SLS springs. In that size, the mtech have 9 turns. Yours have more than 9 turns.

great job on painting everything!

The rears look to be progressive springs. Could they be Eibachs?

Chuckne · Post by **Chuckne** » Jan 28, 2011 10:16 PM

That is interesting. I wonder if the springs got swapped at some point. They were rusty/cruddy when I pulled them out so I assumed they were the originals. I have the original Canadian dealers paperwork (including the lease) from 1987 with the specs on the car which has the mtech body kit and suspension options listed as being on the car. From about 1994 until I bought the car last year there is a void of what was done to it other than the importation/federalization of the car in 2002. I have the original KPH speedo in a box that was swapped out for the MPH when it crossed the border. If the springs turn out to be too soft, I can always swap to something different in the future but thank you for the adding to my knowledge.

Chuck,

I don't think the fronts will be "too soft". Springs with 5.5 turns should be pretty stiff unless the wire is really small. If you can measure the wire size (within 0.1mm) and the total number of turns (coils), I should be able to give you approximate spring rates.

Thanks....I'll see if I can get the diameter measured.

Not so. All DC93 North American specification E28 M5 examples were built with twin-tube gas pressure Boge front shock absorber inserts (31 31 1 133 517) and the same front coil springs used on all North American Spec 535i and 533i models (31 33 1 126 024). In the rear, all North American E28 M5 examples were equipped with hydraulic self-leveling suspension. Bilstein shock absorber inserts were only used in European specification E28 M5 examples produced up to 10/1986 (front: 32 2 225 016 and rear: 33 52 1 129 241).

Can you verify if your stabilizers are adjustable and confirm what color the coil springs and stabilizers were prior to refinishing them?

Best,
RCBMW

I'll have to post my paperwork from the dealership. I tried taking a picture to post but that didn't work. Ill bring it to work and scan next week.

Watching with interest. Great work so far

I noticed that you perviously referenced these Bilstein Part Numbers in another post:

Chuckne wrote: Front F4-P36-0243-H203
Rear F4-B46-0607-H002

The Bilstein part numbers you listed are in the old Bilstein part number format and correspond to the (B8) Sport version. BMW used the (B4) OE twin-tube series only in European specification M5 models up to 10/1986 production and the part numbers you provided confirm that the Bilstein absorbers were installed by a previous owner. I have a suspicion that your car was modified with an early Dinan suspension system.

I would love to see more photos of your amazing work on the M5. Great job!

Best,
RCBMW

Chuckne · Post by **Chuckne** » Mar 03, 2011 11:36 PM

Updated in the first post. RCBMW, I'll check my paperwork. I know the ECU has a Dinan chip so maybe you are on the right track with the springs. Thanks.

That engine will make the car crazy good! Can't wait to see it finished. Great job on the build so far, looks clean.

Love this project.

You had me right up until the S54. Great attention to detail, though.

what i great build

Nice to see that the car is beeing buildt like this

Great inspiration

dunnojack · Post by **dunnojack** » Mar 04, 2011 6:05 PM

this project is completely nuts. i love it! How do you plan to run the S54? euro harness with oem ecu chipped or stand alone? that's what i would love to do... the s38b36 is just a fix for my power desire for now lol

Chuckne · Post by **Chuckne** » Mar 06, 2011 8:35 PM

Running stock ECU that has been burned to eliminate EWS and any inputs from the body side. Had to go with a DBW throttle pedal. From a functionality standpoint, I will have full dual vanos and the only thing I loose is cruise control. Engine will probably have to come out one more time to clearance the tunnel for the 6 speed as I'm not happy with where things are. Otherwise all is sorted.

BMWJustin · Post by **BMWJustin** » Mar 07, 2011 8:01 AM

When I did the 6 speed swap in my Hartge H5s and my fathers 666csi, I simply cut a section of the tunnel approximately 8 by 10 inches out up near the bell housing. I made all of the necessary adjustments using a hammer and dolley, then fabricated a 20mm oversize replacement panel. I welded (now) captive metric nuts to the underside of the tunnel drilled holes in the replacement panel, lined the replacement with closed cell foam and bolted the new cover right on. BTW it makes getting to those top transmission fasteners a bit easier. Just a thought though.

It looks like you started with a nice chassis, and motor. Keep up the good work and keep us updated!
Best Regards,
Justin

oh man, that's sweet. I wasnt sure if the burn was more refined. when i first looked at the swap, i guess there were a lot of questions about how well the ecu would function, but this is good news!

Keep us posted on progress!

You got the jump on me with the Dynaliner on the firewall. Doing that now.

Could you please elaborate regarding the teaser pics of the brake/fuel hard lines? Interested in the larger diameter lines: OE from another model or custom?

Thanks

Chuckne · Post by **Chuckne** » Mar 13, 2011 8:57 PM

Brake and fuel lines are all stock. Stripped them down to bare metal, primed and painted. Must be the camera angle that makes them look larger.
