    I think that this will definitely be beneficial! Unless you have gps trackers in your car and are trying to get rid of them....

    [image: 1520204325579?e=2147483647&v=beta&t=U9hy] The idea of Circular Economy Transformation is reshaping how organizations and societies think about growth, sustainability, and resource management. Traditional economic models rely on continuous consumption and disposal, which creates waste and depletes natural resources. Circular Economy Transformation focuses on redesigning systems so materials remain in use for as long as possible, waste is minimized, and value is continuously regenerated. This approach supports environmental responsibility while also creating long term economic and operational benefits. Understanding Circular Economy Transformation Circular Economy Transformation represents a shift from linear consumption toward a regenerative system. It emphasizes designing processes where resources are reused, repaired, and repurposed instead of discarded. This transformation requires a change in mindset, viewing waste as a potential input rather than an end result. By understanding how materials flow through production and consumption cycles, organizations can redesign operations to reduce loss and increase efficiency. Circular Economy Transformation encourages smarter use of resources while maintaining productivity and innovation. Role of Design and Resource Efficiency Design plays a critical role in Circular Economy Transformation. Products and systems must be created with durability, reuse, and recovery in mind. Resource efficiency ensures that fewer raw materials are consumed while maintaining quality and functionality. Thoughtful design reduces dependency on constant extraction and supports longer product life. By prioritizing efficiency at the design stage, organizations create systems that are more resilient, cost effective, and environmentally responsible over time. Operational Shifts Required for Transformation Achieving Circular Economy Transformation requires meaningful operational change. Processes must be evaluated to identify where waste occurs and how it can be reduced or eliminated. Operational shifts include improving material tracking, enhancing reuse practices, and aligning internal systems with circular objectives. These changes demand coordination across departments and clear commitment to sustainability goals. When operations are aligned with circular principles, organizations can reduce inefficiency while strengthening overall performance. Environmental and Economic Impact The impact of Circular Economy Transformation extends to both environmental and economic dimensions. Environmentally, it reduces waste, lowers emissions, and conserves natural resources. Economically, it supports cost savings, improves supply stability, and creates opportunities for innovation. By reducing reliance on finite resources, organizations gain greater control over long term planning. The combined environmental and economic benefits make Circular Economy Transformation a practical strategy for sustainable growth rather than a purely ethical choice. Long Term Value of Circular Economy Transformation The long term value of Circular Economy Transformation lies in resilience and adaptability. Organizations that adopt circular practices are better prepared to respond to resource scarcity, regulatory change, and shifting market expectations. Circular systems encourage continuous improvement and innovation while reducing environmental risk. Over time, this transformation strengthens reputation, operational stability, and stakeholder trust. Circular Economy Transformation is not a short term initiative but a strategic approach that supports sustainable success for future generations.

    One of the wheels might be an updated version, a spare, or sourced from a different casting facility. I'm not quite sure which BMW's were all offered with style 44's, but if there were multiple models offered with the same wheel, they might have a different place that sources the same style wheels. The other reason could be casting improvements or a lack of material in a region that was producing wheels and they switched suppliers. Either way, I find it hard to believe there would be a "replica" of a style 44 as its not a highly desirable wheel.  I could also be very wrong as well, who knows.

    i think it was a good choice to return, considering the pitting is not repairable. had similar pitting on one my e34 calipers that ended up nearly locked up. now, the guide pins were pretty bad too, so its hard to say which was the #1 culprit, but they would have bad hard to trust as a rebuild.

    Thanks, I appreciate that perspective. I’ll try thinking of it that way next time and see how my brain likes it. That or  i’ll start making right turns from the thru-lane just to feel like I have the right of way.

    Ras said: How do i delete the ews? I have a 97 318is, lost the original key with the remote. Starts occasionally with the spare key however yesterday it locked by itself and doesn't wana unlock and its not starting (cluster lights comes on but no crank).  I texted Jeff to let him know, he's not on here much anymore. The OP was dealing with a OBDI car with EWS, it's simpler as you can just swap out the ecu/dme for a earlier version. I'm not sure how the delete works on OBDII cars.

    I would recommend E-coat. PPG E-Coat Powercron 6000CX is a semi-gloss black electrostatic liquid coating. Think powdercoating, but liquid instead of powder. The benefit of e-coat over powdercoat is it is very good for tight tolerance/holes/features where you dont want coating buildup/uneven thickness. Its a commonly used automotive coating. The downside is it is less UV stable than powder. Try Swiss-tek or Hartford Finishing [image: image.thumb.jpeg.eee68af3d352c361a43940bba2f8e387.jpeg]

    I'm using an 0w40 synthetic to take advantage of quick flowing oil during cold starts and adequate viscosity where temperatures get higher. Will probably switch to 5w50 in the summer since I prefer to have the windows open vs run the AC.

    HipMF said: Sounds like a CV carb. Presenting the fueling system with a step-change in manifold pressure makes it's job a lot harder. Most of the sensors that are used to measure what's going on in the engine have some sort of time-constant associated with them, so the computer only knows what happened maybe 20 or 30 milliseconds ago. Meanwhile, it's trying to guess about what the correct parameters are for the next combustion event when the current one hasn't even completed. Slowing down the rate-of-change helps it to guess better, which should result in better combustion. There are probably other issues as well; the air that's rushing in to the intake manifold to bring it up to ambient pressure has mass and therefore inertia, so there's likely to be a little bit of reverberation in manifold pressure until everything equalizes.That's the most likely explanation I can come up with for the CV carb. Air could even potentially flow backwards through the carb, which would cause it to get fueled 3 times before it got into the engine... Very interesting. I hadn't heard of that before but it makes a lot of sense

    B C said: I only just saw this thread/the video. That is awesome and I think you should leave it   can you replicate the noise anytime you want? Or is it very random It’s every time. I’ve only been able to very faintly get some audio to come through on an AUX to tape deck. Ben had suggested possibly ground issue. But my assumption is it could also possibly be the amp. My audio knowledge is very limited.
