    Now available for the MZ3 - lifetime warranty FCAB/LCABs



    The ultimate front control arm bushings (FCAB)



    Replacement hybrid design front control arm bushings use a true rotational bearing built into a high-durometer bushing material. The net result is racecar functionality with near-OE levels of vibration and noise damping.

    LIFETIME WARRANTY
    Even for track use!

    Complete assembly (exploded):


    Inner rotational bearing:


    Racecar durability testing:

    The OE design of the FCAB is a simple rubber bushing. The part itself is subjected to torsional forces (twisting), lateral forces (side to side), and longitudinal forces (in and out). While this basic rubber design results in a quiet and comfortable ride, it also wears out quickly and has negative effects on performance/enthusiast driving. Specifically, the indicators of worn FCABs are steering wheel shimmy, looseness in the front end, irregular tire wear, sloppy steering response, and suspension geometry changes while cornering.

    UUC's all-new design incorporates many unique features designed to permanently address these problems while giving the functionality of a race-spec component that also maintains normal street car comfort and vibration absorption. Rotational bearing accommodates all torsional forces without affecting outer bushing material. Bushing material absorbs noise and vibration.

    Results will be felt immediately as improved steering response and feel, and a more "connected" feeling with the chassis.

    Important: These can be purchased complete with the steel "lollipop" bracket, or just as the bushing itself. Original bracket can be re-used, new bushing must be pressed in.

    No downsides.

    No squeaking or any sound at all.

    No harsher ride, except that it always feels like you have brand-new bushings.

    There is a bit more crispness to the steering... if you thought the steering feel was awesome before, prepare for a pleasant surprise!

    The reason for the "best of both worlds" effect is described above. We're using a rotational bearing-like device for the arm actuation, yet it is fully rubber isolated.

    Just want to confirm those fit in the stock lollipops? I ask because SCCA IT rules would allow the bushing, but not an alternate lollipop.

    Yes, stock lollipop.



    Race legality was a concern when designing these, which is why it is a true bushing and uses the OE brackets.

    As noted on the website, you have the option of getting just the FCAB part so that you can press it into the lollipop brackets you already have, or for the added cost of the brackets, we will press them into brand-new ones for you.

    What would you say are the differences between yours and the powerflex bushings that i put in my car?

    power flex has that same slip style bushing.

    the purpleish blue insert spins inside the black portion.





    Also what are yours made out of.

    Covered this a bit in a thread on the M3 board:

    http://forums.bimmerforums.com/forum...2&postcount=11

    Yes, but the differences remain that the urethane is still being torqued in multiple planes - the black outer part is still under tension/compression and lateral loading. Urethane generally does not like extreme multi-axis forces, which is why it is common to see urethan FCABs fail.

    You're also looking at urethane spinning within urethane just about constantly. Should be interesting to see how the lubrication in that high-grit environment under the car holds up.


    Also what are yours made out of.
    From outer to inner, ours is a steel sleeve with better-than-OE grade automotive rubber (thinner = higher durometer), and the rotational bearing assembly which is a few pieces of various high-tech materials with integral lubrication properties.

    Well I was going to refrain from asking about comparisons, but since Rob seems willing, how would you compare these to the treehouseracing.com eyeball arm bushings. To say the very least, you bushings are the most expensive out there...

    The Treehouse Racing part is really very nice, in fact we've used that on some racecar builds. But for comparison, it really should be considered a race-only part. As it is solid metal with a delrin-like liner, it has no vibration absorption characteristics at all. Street use is very different from race use, and what lasts a long time on the track may take a beating on the street, and the pounding of potholes and regular road irregularities can pummel that bushing into submission and create some looseness.

    I always thought the treehouse ones would wear out quick. but other then that probably have the best effects on handling.


    the thing that i have noticed about the PF bushing is that they seem to spring back when i hit a bump (not up and down from hitting the bump) but more like (looking at the side of the car) a front to back spring action. . .that has kind of a jitter effect. now that might just be me needing to buy new struts for the front but it is a lot more pronounced with these bushings.

    thank you for your professional response to my questions rob

    I don't know if this is still the case, but I seem to recall that the Treehouse Racing bushings were an offset design rather than centered which is what I think we have with the stock MZ3 part.

    Rob, can you confirm that your bushings are the same geometry as stock MZ3 bushings?

    Thanks-

    Yes, same geometry as the MZ3 bushings.

    The offset bushings are used in the 1995 M3. 1996 and later gets the centered design and revised control arm geometry.

    All MZ3, including all S52 and all S54, use the exact same part numbers for the bushing and bracket as the 1996+ E36 M3:

    IMPORTANT!

    Based on recent inquiries, I just realized there is some confusion as to the pricing on this part.

    The pricing on the website is per PAIR. You get the complete set of two bushings for the price, you do not have to buy the item twice.

    I will be getting these bushings from you Rob. I was going to be getting the Treehouse bushings, but now I am going to get these with the brackets as well probably in a month or so.

    I am excited about this!

    P.S. So for my M Coupe with the bushings installed into your brackets, how much would I be spending?
    “If the representatives of the people betray their constituents, there is then no resource left but in the exertion of that original right of self-defense which is paramount to all positive forms of government, and which against the usurpations of the national rulers may be exerted with infinitely better prospect of success than against those of the rulers of an individual State. In a single State, if the persons intrusted with supreme power become usurpers, the different parcels, subdivisions, or districts of which it consists, having no distinct government in each, can take no regular measures for defense. The citizens must rush tumultuously to arms, without concert, without system, without resource; except in their courage and despair.” – Alexander Hamilton, Federalist No. 28

    How difficult is the install? I had something similar on my Subarus (anti-lift kit) and it was a simple matter of unbolting the bracket and prying down the control arm slightly to get the new one on.

    Is an alignment necessary after the FCAB is installed?

    Any changes to caster?

    same same.

    search my threads that i have started. i did a write up on it when i installed the powerflex bushings.
