Yes, that would be a solution, because the "fixed" secondary attachment place will always make the wheel rub the mudguard under heavy compression. Or, even if this happens rarely and is of no great concern because it won't harm the tyre, the truth is that the mudguard will be under permanent "flexing" stress as long as the car is rolling and the suspension is working. And flexing in ways it was not designed for, therefore stressing also the secondary attachment spot.

However, I think the ideal solution would be one that had the mudguard secured in two points more apart from each other. I don't have my M3W yet but I've also wondered about this a bit and if it is at all possible to get this done using the suspension arm or even better, the rear axle as support for something, than it would work well.

Since my English is poor when discussing technicalities I hope you don't mind me using your drawing to illustrate what I mean. Here goes:

I like the concept of a swingarm mounted fender as you can keep it closer to the tire without fear of it hitting the tire.

But using aluminum for the support would probably not be my choice. Aluminum stress hardens and will most likely crack and break on you.

What Mario suggested is what I was thinking about too. A three point attachment would be the best all around. With the plastic fender, it's not like you have a lot of weight to support.

I spoke at length with the guy at Alro Metals, where I acquired the strip from, and there are different aluminum alloys. The one he sold me cannot be welded but should hold up to bending and shape retention, according to him.

I have over 2000 miles with my current setup and there are no signs of wear or stress on either the mudguard or any of the brackets.

Mi3Wheeler, you're probably correct about the aluminum.

All I'm saying is that right now you have a stationary aluminum mount bolted up solid at both ends. If you have a new aluminum mount cantilevered from just one end it will be like a spring bouncing around a bit and aluminum just doesn't spring very well in general terms.

If he agreed that for your application the piece he sold you will work, he's the expert, not me.

We're a manufacturer of plastic production equipment and we use tons, literally tons of aluminum and it's great to reducing weight etc. But not used where any major flexing is taking place.

By the way, I'm a Michigander too. But I moved down the greater St. Louis MO area in '02 for work and unfortunately still here. My homestead area is the Clare Farwell area. I drive by Alro on my way up to Clare every Christmas. We used to buy lots of items from Alro when I worked in Beaverton MI at Lyle Industries, another large plastics machine manufacturer. I think we bought out of Saginaw, not the Grand Ledge area where their main MI warehouse is.

Sorry for rambling on and on...

Yeah, the drawing I have above is just my initial concept of a mount that does not require 2 points of attachment. I have not started working on this project yet as my current set-up hasn't made me feel any urgency to change it up. But the idea and some all of the materials are there, I just have to find the time.

My rear mounts articulate, so allow the mudguard to move and flex. It is mounted 2" from the tyre and has never touched it even running 2 up with luggage.
