Poly based strut mounts on exchange

I worked out a replaceable polyurethane strut mount bushing design for the early strut mounts. I will rebuild yours on an exchange basis for $195 shipped U.S. These are hand lathed solid 60A red polyurethane and should last a lifetime....No sagging even with an ironblock installed.... PM for details.....

POST from my thread "Nailed It"....

These inner strut mount donut absorbers feel like stiff foam and less like rubber (may be corroded) Anyways they collapsed under the weight of the V8/old bushing/ 120mph stoppies LOL. The strut top rebound washer is sticking past the stop-rings by 3/8" and I am hearing the rebound clunk.

I found that the 924 stop-rings will fit. Porsche/Audi part# 477-412-411. I have to get a set somewhere,
And Audi part# 0403-214-20 is stamped on the strut thrust bearing. Did some research and INA 823412249, and part# 357412249 are a match. I'm not 100% sure but I think the 1J0 412 249 is an upgrade with rubber seals that fits later VW's. Anyways I have my new thrust bearings and won a 4" x 8" stick of red 60A polyurethane from Ebay. The poly is easy to lathe but also easy to efup so it took me a few hours to get them done with the mirrored dimensions of the old 944 absorbers and I added 1/8" to the height dimension so they will last forever......

Xschop,
Would you consider making a set from a more durable material like Delrin, if asked?

Thanks

I can if sent a 4" round by 6" stick.
I can't imagine putting that in there, it would cause lower lumbar calamity. The 60A gives just enough to absorb the ball-joint impact in the control arms IMO. The no-give Delrin would cause quick wear of those aluminum arm joints.

Also I silicon greased the bushing interface to lower strut cup interface and the steering is amazingly smoother.

Waiting on a set for the late models, have you priced a set of those lately?
Thanks as always for the hard work Rob!

What's the geometrical difference between the two? To me it looks like Porsche just beefed the rebound rubber on the LATE mounts. I measured every spindle and there is only a 4 degree difference between early and late offset strut angles. It wouldn't phase the early PU mounts to install them on Later cars.

You can use early mounts on a late car but have to cut the centering stud off under the fender. No biggie and it's not needed anyways.

Or drill a hole in the EARLY mount where the LATE mount positioning hole is?
Thanks Dawgz for the info.

I have an extra set of early mounts. I can ship them to you if you want them.

I'll take them. This is great news. I just looked at what Pelican wants for new Late rubber based mounts.

Is that Pelican price a TYPO LOL

CRAP!!!! I threw away my late mounts, I could have sent you those too.

I will make the lower cup interface angle an extra 4 degrees for LATE strut mounting.... It's almost a waste of time as I'm doing the calcs.

"""""CRAP!!!! I threw away my late mounts, I could have sent you those too..""""

I just need the LATE mount hole diameter and X-Y dimension in relation to the fastening stud centers and I will drill the Early mounts for someone with a late car so they don't have to grind/cut the spuds from their frame....

So if you want to convert over, make sure you get the lower bushing cup and large top rebound washer with the base plate....

I took another spare mount that I had and drilled it for the LATE car frame spud and rebuilt it with some poly bushings that I gave another 4 degrees to the inner cup. Painted with high temp wheel paint and will come with larger/longer bolts and nuts for a strut brace (optional). I will ship these for $225 anywhere in the U.S. Also don't forget to get the sleeve bushing that goes between the lower cup and top rebound washer.... Just PM

I made another set of these. Just let me know if you have an early or late car and I can drill the extra hole for late cars if needed.
Same price $225 shipped anywhere US-48. Just Pm[You must be registered and logged in to see this image.]

If anyone has any spare early (86 and below) strut
mounts let me know.
