I don't know if this was a good idea... / BMW F10 Alcantara trim cover from Aliexpress
Просмотров 3314 месяца назад
I was searching for a bit different look for the trim covers in my BMW F10 M5. I found these Alcantara trim covers/stickers on Aliexpress that are precision cut and are supposed to simply stick on the original trim. I had a carbon vinyl on the trim but it looked too fake, so I switched to piano black trim. Let me know what you think about this Alcantara option :)

    Personally i would attempt to renovate the parts and just change the gaskets and bearings. However since the problem is fixed to your satisfaction it is all good! Also, i would attemt to prime the part with zink and paint it with a 2 component epoxy paint. Just brush on paint of course, it would help with scratches since epoxy paint is crazy resistant to physical stress. good job though, if i were to suggest a tool, getting the M12 FRAIWF12-0 from milwaukee or something similar would help you in those tight places.

      @ricbarker4829 3 месяца назад

      If the grub screw isn't tight it will probably fall out unless you loctitie it in. It doesn't really matter either way. It is a cheap Chinese design with no inner bearing bushes. If the grub screw is tight, it just means the pin is stationary in relation to the two outer holes and rotates in the centre hole. All the wear will be in the centre of the pin or the centre hole. If it is loose, the pin will be allowed to rotate in all three holes, sharing the wear. These are really only designed for domestic use with low cycles compared to a shop lift. You will wear out before the pins or holes will, which is why they don't bother to install grease fittings. As the pins are a sliding fit to the holes, most of the grease was pushed out when you refitted the pins.

    loud musig: I adjust the volume, than I can't hear you. I am not interested on the music at all!

    I have been looking for a budget lift for my garage here in the US. I really don’t care if it’s made in China as long as it’s solidly built and it’s within my budget. I like the design of this one and it seems pretty well made to me. Plus it has that open middle area which I want. And I have to say you did a good job rerouting all those lines. The electrical work was done very well…..kudos my friend.
