Not sure - I chose Z4 3.0si in Turner's website, and it said "It Fits, but Z4M says "no bueno". Odd.

They won't list the M3 product as a possible fitment for a couple of reasons. First, if the monoball uses BMW's factory lollipop, the M3 lollipop and the MZ4 lollipop are not compatible. However, I've NEVER seen a monoball use factory lollipops. They're usually custom build and constructed brackets. In that particular case, check and see if there's an additional bolt hole machined/drilled to accommodate the M3's reinforcement plate. Again, it's unlikely, but the E46 M3 LCAB has an additional mounting point for the factory reinforcement plate. It appears Turner's monoball bushing does include that additional reinforcement plate mounting point. You can probably machine that part off and it'll fit the MZ4/Z4. If we're talking about the monball bushing by itself, it won't fit for sure. I don't remember off the top of my head, but one or the other is a 60mm outer diameter and the other one is a 66mm outer diameter (okay, if I have to guess, the E46 M3 uses a 60mm bushing and the MZ4 uses a 66mm bushing). There's actually a reasonable degree of likelihood the "kit" version that came with the M3 lollipop will fit without having to shave off the additional mounting point, as the reinforcement plate under the MZ4 is the same as the E46 M3. You might even be able to bolt the plate onto the lollipop to give it an extra secure location for some added stiffness.

This one should be a direct bolt-on, you lose the offset bushing and some caster but gain in the stronger, stiffer monoball bushing.
https://www.turnermotorsport.com/p-3...with-housings/ The operative word being SHOULD. I'm at 95% certainty.

Well, I own the nonM z4, there is no 'castered' FCAB. It has always been the centered version as above. I've never tried increasing caster now that you mention, but hasn't been a noticeable issue thus far on performance for me.

I ran the offset version (zhp) but went back to centered because the increased caster led to rubbing against liners pretty badly. Something to keep in mind considering your current aggressive wheel fitments.

I bought the ones without the housings and just pressed them in myself for about a $50 saving in price over the kit with included housings. Here is the LINK for the part I ordered.

Same here. Had my first track event with them. I also greased them properly. So far so good, nice and solid and one less thing I need to worry about.

I pre-press these TMS units for the e46m3 folks over here:
http://www.m3forum.net/m3forum/showt...post1067846871 The housings will fit Z4M. As pointed out, only centered units are available. |

What was your ride height difference, tire width & (tread width), wheel offset, and camber that you had with the offset lcab? I need to do some refresh on the coupe and am trying to decide if I want to stay oem staggered with slightly different offsets with apex arc with the offset bush. My goal is to reduce understeer and with the lack of room for wider with offset bush, would a 255 (on my roadster lowered 1”) square with neg camber be more beneficial than the offset lcab with 225-245 tire width up front 255-275 rear.

15 years ago, I tried using Powerflex bushings on my E30 M3 track car. Both the FCAB and the rear semi-TA bushings distended after only a couple of events. Popped them out and trashed them. Bought AKG. They lasted about 2x as long but eventually failed in a similar manner. Again, wasted money. Went back to the factory M3 solid rubber bushings. I was no slower and my problems all went away. I had similar problems with urethane motor mounts for that car. I only got away from continuously failed motor mounts with the 7-series mount which was much more substantial and had the added benefit of lowering the motor ~1/4" and shifting it back ~3/8". If you're going to bypass the rubber bushings, I'd say to go with bearings. However, this will help you locate the next weak link in the chain pretty quickly. |
