Hey guys...I'm (finally) getting caught up on editing this holiday week. The latest episode of the Bumblebee series is on the rear suspension and brakes. Hope you find it helpful.

Thanks agaiin to the gang at 914rubber @Mikey914 and PMB performance @Eric_Shea for making great stuff to keep these cars going. Links to parts in the description on YT.

This video shows new 100lb springs from 914Rubber and finishes the installation of the trailing arms with their new pivot shafts

Happy holidays!

Fantastic - break time from a MasterClass to the 914 Master Class!

Nice!

Another terrific, informative video that gives all of us amateurs the confidence to work on our own cars. Thanks and Happy New Year Ian.

No shock bumper? That stepped washer looked to be actually the remains of a bumper where the rubber portion had perished & disappeared

I thought on these bilsteins the stop is integrated, no?

No shock bumper needed with gas rear. There was no large washer on shock hat, #9 in diagram

Thank you for the nice video!

Can't wait to watch it again, when I get to this step!

#6 in Mark's diagram

Thanks, Rich. i'm aware of the part...just thought that it was integrated into the design of the Bilsteins. There's no mentionn of a stop needed in the installation instructions.

Anyone have info to add about the bump stop? Curious..

While it may be true that you probably shouldnt ever have an issue switching from oil to gas damped shocks, I still install the Koni replacement bumpers (pictured).
I was just pointing out that the stepped washer you reinstalled in the Vid was actually part of, or the remnant from the OE bumper.

Thanks, Rich. Those bumpers are probably a good idea...cheap insurance. I'm not sure about the origin of that washer. But the entire setup seemed to be original. I don't know why there wasn't a washer under the threaded collar, either. I just maintained the same arrangement. If the brain trust here feels that wasn't a good move, I canl def make adjustments.

Factory bump stop similar to this one only orange color. Washer was molded into the base. Rubber disintegrated over time, leaving only washer.

So...I guess the washer should still be included (even without the stop) since it affects how the hat sits and the length of the rod protruding from the mount.

Correct on the washer, you need it even with rubber missing.

Hello all. I am about to start this same job with, coincidentally, the same Biltsteins and springs. What is the recommendation - is the “supplementary spring” (I think that’s what it is called in the Haynes) needed or not? Thanks!

Confusing.. I read only the front Bilstein's have integrated stops.

Rear Bump Stop Option – Use existing bump stops or replace them with our progressive bump stops.
Curious has anyone used the stoddard rear bump stops? Does the pointed part point down towards the shock?

The picture makes it look like the dome part faces up. The manual shows the dome part pointed down.
The stoddard part also looks like a washer goes on the flat fat side. Where can you find the washer?
