HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Poly based strut mounts on exchange

Post  xschop on Tue Feb 22, 2011 4:12 pm

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.

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 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....

Polyurethane strut mounts for LATE cars are available.

Post  xschop on Sat Feb 26, 2011 6:18 pm

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
