Hi Gens,

First of all I want to thanks to Sir. Mike Ottati to let me post in the main section.


For those who are interested in Soft Ball Upper spherical bearing bushings it is worth your time to read the following:

Intro. It has been 12 years since I started messing around with E24 M6’s E34 M5's E30 M3's, E31 ‘97 840Ci.

With the factory upper control arm bushing design on our cars, we are all aware that it causes the very famous and annoying front wheel shimmy around ~47-55mph, as well as the destruction of the power steering gear box!!! I have seen many cars such as E34’s, E24’s, and E31 including my own E31 L (when I got it from the previous owner) with excessive steering gear box play. Many owners ignore the shimmy until it gets really bad, and then they replace the bushings over a very short period of time…with E32 7 series aka “Green”. The E32 7 series can hold max 15k miles (in my hands even less..)or less with your favorite wheels with low profile tires…and then again requires replacement. Every little shimmy goes directly to your steering box and slowly destroys the gear inside. Many people put the blame on the design, but that is not the case.


My personal experience: On my personal daily driver E24 M6, I have Throwing Stars 9j/ or my other set: BBS E26 17 9.5J wrapped with 255/40/17 tires on all 4 corners. I have replaced so many E32 7 aka“Green” bushings that I can’t even remember how many sets… and every set was installed when the car was on the jack sitting on all tires in order to release the suspension/tire preload, (drive in lift). Another downside on the factory poor bushings design is that when there is hard breaking, the geometry visibly changes on the front wheels.


The inventor on this Unique “SoftBall” spherical bearing Design is my friend: Sir. Frank Fahey. Back in 80’s, he invented this design and with large success and until today, the cars these bushing were installed on has NEVER had any problem with shimmy and they are still rolling!!! Quite some time since 1980’s…


The downside of the competitors is that….You will notice immediately the Harshness! I have done extensive testing on our competitor’s product by installing brand new 16inch tires with 225/50/16 with Super soft tall meaty side walls, even different tire pressure and they are STILL harsh when driving over potholes! You can feel the force going straight to the frame bracket/chassis! Second test: I installed my 17inch Throwing stars 9J all around with 255/40/17, and I felt every single imperfection on the road in my steering wheel. Worst part was that all the forces were going to the Upper Control arm bracket. Unfortunately, in time this will cause possible cracks. Not to mention, this will shorten the life span of the other suspension components, especially the Ball Joint on the Actual Upper Control Arm! You eliminate a shimmy problem but you destroy the ball joint on the other side of the arm and on the other components from the suspension. Also another point is that the factory arms are not design for such a bearing design. Another downside: you can feel the tire thread noise because it transfers through the entire chassis. In my opinion, these kind of bushings are race track tubular arm design…I can say from personal experience that heavily modified racetrack suspensions do NOT work for the street, only for racing!


What makes our “softball bushing” unique and better than our competitors: In our bushings, we use Military Aurora Bearings that are made in the USA. The most important factor in our bushings is the Poly Urethine layer. This layer is used specifically as a cushioning to prevent suspension impact. It also prevents cracks on the bracket, protects the ball joint from wear and also preserves other suspension components.

Aurora Bearing. Stock bearing has a radial load capacity of almost 32,000 lbf, which is WAY overkill for our application (we need at most 2000 lbf for 1 g braking and 4000 lb weight). The COM-12KHT alloy steel race raises load to about 48,000 lbf (overkill).

Is our Bearing Serviceable? Yes, on our product you can replace parts.

Our product does not have rubber seal to prevent dirt and dust going in: Correct. We don’t have the rubber cover on our bushings. Our bushings are so tight that dirt is unable to get inside. Frank installed it on his clients M635CSi/M6 and when the car came back for service years later, the bushings were still in EXCELLENT shape and NO dirt was inside. I personally have had these on my daily driver for years and they are in as good as shape as the day I installed them.

Fitment Our Bushing will fit all E34, E24, E28, E31 Models. Please specify so we can sent you the correct bushing

We manufacture these bushings also have them on our cars M635CSi and my 88' E24M6, E31 840Ci from 5+ years….

To get an order for our great “SoftBall” bushings please reply to the post with your forum user name and your name.

Thanks for your time reading all the above.

Price is $349.00 The price will vary depending on how many sets will be ordered.

Regards
Anri

Yes if the other mods don't mind to let this sit here for a bit, we get such little traffic on the group buy/for sale page. I am certainly interested in a set of these.

Note: under 'fitment' you don't list e34. Now i know if they fit e31, they fit e34, but maybe you should clarify that.

Mike I missed the E34 chassis.

Our bushing is the same for all E34, E28, E31 models. Note the spacers are the one will judge either E34 or E24 or E31…

So I know the exact spacers I will sent to E34 owner or E31 owner.

Will these fit a 1985 M635CSI? I am still chasing the shimmy, have custom made thrust arm bushings made just not installed yet.

Hi Anri,

this looks interesting, anything that can improove my "boaty feel steering" in my E34 is welcome. What's the difference of this kit vs the e31 850CSi (or e31) spherical bushing control arm?

I have bad roads here.

Same question as Diego. The roads here are quite bad too.

Diego,

The bushings itself is all the same for all models E24, E28, E34, E31.

The Spacers will make the bushing fit either E31, E24, E28, E34

Again, for you I will put in the box spacers that will fit your E31. If you get a second set for example for your E34 M5 I will put the correct spacers that will fit the E34 M5.

Perhaps its all clear now ? Bellow I am attaching you a picture.

Please guys take a look and inside the plastic bag are the E31 spacers.

Yes the "Boaty Steering feeling" will go away using our bushing and they are perfect for bad road because we have the poly cushion to take away the road forces.

Hi Anri,

Hugo,

Years ago when I sow Power flex company to made Black Bushing for our upper control arm I immediately purchased it and install it on my car. It felt great till later when I broke an arm on the parking lot after very heavy canyon fun with 255 R-888. I was lucky an glad that happen right on the parking lot because I can not put the scenario when you drive with sticky tires at 11pm night time on canyons. Also the other side it cracked and I will keep the arm just for example why this is not a good design.

Hugo, just think what upper control arm is doing. 1. When you make turns either left or right the arm is tend to move just a little bit in the direction of the turn again either left or right. 2. Now apply approx. ~3400 or 1500kg load on a turn with sticky tires say around .05 to 1g all these forces are going direct on the entire suspension including the upper control arm. Bottom line with 2 words is that having the Power Flex Bushing design fixed without the ability to follow the direction/move the energy of the side forces are going direct to the actual arm.

The E34 M5 when its lightened like yours is raising up to approx. balance to around +/-54F-46R% with one word nose heavy. When you have such Fixed Power Flex bushing concept design the side load Forces are going to the arm by the bushing side were it gets thiner because there is the weakest point of the arm as a total length.

The Original BMW Design bushing is mushy and can flex and can fallow the direction of the arm and can also absorb the road forces. Also the OEM Arm is not designed to get such a heavy load forces ! That is why our competitors arm using metal to metal design is not good either because the danger of broken and cracked upper control bracket it does exist and short life span on the ball joint side. Also the harshness is another concern in such a hard ball design.

Hugo, in racing suspension 90%+ all the arms are made from spherical bearing in a such a critical arm points specially when they are involved to hold the wheel as on our cars and tend to move. Sureeeee I will buy Power flex bushing for the rear subframe no proooooblem but never for arms.

This is just e concept I have and direction I follow.

Hope to clear a bit the concept of Fixed bushing installed on upper control arm that is designed to move around.

Anri

Super interested in these, seems like a fantastic concept.


I may have misread your comments, but how are your bushings 'softer' or more flexible than powerflex black? The construction of these appears to be mostly steel and spherical bearings with only a thing layer of urethane.
