I gurantee faster lap times at every track. 1-2seconds or I'll buy the kit back from you and send you replacment control arms.

Why do I suddenly feel like I'm watching late night TV? Do you have a dog named Spot? (IMG:style_emoticons/default/biggrin.gif) My car is getting a lot of work done and I'm pretty sure it just got polybronze, I'll check Monday. I don't like being clueless but I'm that busy at work.

I have Mike's bearings on the front and they are very slick. The back still has regular Weltmeister type bushings and hasn't been apart in a couple of years but I might look at the polybronze for that end.

The roller setup is the single best suspension improvement you can do to the 914.


mabe I could get rid of the 450# and 350# springs in my car if I got something that let the suspension work the way it should (IMG:style_emoticons/default/laugh.gif)

Ira from Tarett engineering has one roller bearing kit left in stock for a 914.

AFAIK Mueller wont be producing them again unless demand calls for it.

what constitutes "demand"? I want 'em (fr + rr). $900? Anyone else?

I went with the poly/bronze as they are $100 cheaper and Mueller was out of roller bearings when I wanted some.

I still need to do the rears so maybe if Mueller does another run for the BBS store????

ChrisC,

Then why does Chuck use a picture of your car for all his ads? LOL

I had no idea you didnt have poly bronze in your car!

I knew it had roller front.

Needle brgs *should* migrate around their cage thus presenting different rollers to the loaded (uppermost) areas....that coupled with the tight clearances of Mike's set-up
don't allow much "slop".

The polly bronze presents the same area to load constantly.....same as the plastic jobbies that wear oblong given a year or two...BTDT took pics.


oh.....them needles still ain't worth spit (IMG:style_emoticons/default/blink.gif)

I will agree with everyone here, JP's car has them front and rear and it really evens out the bumps on the harsh surface up here at PIR. I am trying to get a passenger seat from Craig so that we can put it in JP's car and take people from rides...you can take a ride on them rollers then.

I made a few sets awhile ago, just the rears though. It wasnt too hard.
A couple memebers here got a set and I ebayed the rest. I still have some of the end studs available/ free if you want some. You would need to source everything else out and have or know some one with a machine shop.
A few of the supplies:
25mm stainless steel rod
Nadella needle bearings 25mm ID
Thrust washers
End studs
Outer steel pipe that the bearing slips into. I dont recall the diameter and wall thickness.

Anyone used the Shine set? (scroll all the way down)

I've used some of their stuff on my VW and the build quality was ok.

dont harleys use a needle bearing in the suspension pivot?
if what i've been told is correct, that bearing can wear notches in the race from the bearing 'not' migrating. Resulting in a washboard surface on the inside of the race. Once you get a wear groove started then the bearing definitely will not migrate. The small contact area of the needles could contribute to this no?

maybe?
definitely not?

736 - thanks for the inspiration, but my skills and tools are not up to the task.

SMD - nice to see other options! Those cost more than what I've been *told* the ones from our west coast 914club guys will cost.

I've seen a recent install with grease fittings, and if the bearing was properly lubed and functional it would be free to spin inside both races without causing grooves. Winter will bring more tear-downs and rebuilds, and I'm sure there will be some more reports on the wear characteristics. Ok, back to waiting for a production update....

I was the proud winner of a front set at the WCC last year. I found the hardest part of the install to be the teardown. Putting it together was easy and Milke provided online support via the club (Thanks Mike). I made several changes at the same time (Five lug, turbo tierods, wheels and tires), so it was hard for me to guage the difference. I will say that i am very happy with the way my car handles these days. I had the car on a lift last weekend and an external inspection looked very good. I tried to move the A-arms and found no play in the bushings. Everything looks good after a flat tow x-country, a few ax's and 6 months of the streets of Jersey. I plan on pulling them for inspection in the next few months and will report the status.

Here is a like to my install Mueller bearing install and 5 lug conversion

I also would be interested in a matching set for the rear (IMG:style_emoticons/default/clap56.gif)

- anyone out there with some experience? preferably someone who did a install himself. and has driven some cars to compare.
- is the install really that hard?
- what about dirt getting into the bearings?
- change of effective springrate due to not fighting sticky rubber bushings anymore?
- got pics?


i still got my set (rears) in the box, they'll be going on the new trailing arms ...
(IMG:style_emoticons/default/smash.gif) Andy



Here are some pictures (IMG:style_emoticons/default/blink.gif) of my trailing arms after the Chris Foley (strengthening) and Mike Mueller (bearings) treatments. I really like the extra work performed by both Chris and Mike.

While the installation of the bearings is fairly straight forward, it is important to be sure the bearings don't rotate in the tubes. We did some blueprinting to be sure the crush on the bearings, relative to the tubes was correct.

We also installed different grease seals.

With all the special work these trailing arms tooksome time, but together with the new "Porsche" U joints, will be pretty nice on the little silver machine.

The rotation on the trailing arms is soooooooo smooth & tight. (IMG:style_emoticons/default/happy11.gif)
