Hello, Does anyone know where to buy the rubber extender extrusion? I need about 80mm wider than the existing arch, so probably 100mm according to the automotive engineer.

There is an option order code for Widened fenders from Mercedes, not sure if you have a dealer, it not you could try Atkinson Vos, Hellgeths, UniDan, Expedition Imports (shipping would suck, I know) etc

Thanks tkv000.

I was hoping to find a rubber extrusion. The 395 tyres need a 100mm extension to be legal. I found 75mm wide easily enough, but not 100mm wide to date. Unfortunately looks like I might have to have a metal worker slice the existing guards, and insert a 100mm strip i.e. extend the existing guards.
Does anyone have any other options. I cannot be the first to come across this issue, as dozens of vehicles sport the 395 tyres here in oz (the wheels are brought in by the container load).

The 75mm version does not even cover the tread pattern let alone the side wall.

The generic poly guards truck shops sell worked for me - they are pretty wide and I had to trim mine down. At about $60pc it is a good solution - plus, they do not rust ! I just removed the brackets from the originals and used them on the new ones.

I don't like the idea of cutting the edge off either. Its what provides the rigidity. I don't want a floppy dodgy-brothers arrangement.
I think there are only two proper choices:
  • Find a rubber strip with the correct profile (as in the sketch I provided yesterday). Apparently, Pattechniek (Netherlands) sells a 100mm wide rubber strip and a 150mm wide version to suit the 437. I'm in the process of checking if the profile is correct.
  • Fall back, is to get a local metalworker to insert a 100mm wide metal strip.

Purchased some 75mm wide rubber guard extension strip. Came badly distorted as shown. Supplier says I can turn it inside out for a few hours and should come good. But its been in the sun for two days and still no change. I also purchased some 50mm a few months back, and it came in perfect condition. I think its stuffed. I'm inclined to send the 75mm back, and try another supplier.

I'm wondering if anyone else has had some experience with this rubber strip?

I recon its been stored badly, and the distortions are permanent.
