80's BMW 635CSi Info for a Confused Stefan

A video I shot while helping a friend work on his 1985 635CSi to give another friend some information. Or something. I don't even know.

TRX Wheeels ? - uhhh - i exchange my to inch because new tyres are diffecult to get in germany for those. Btw repaint your rear spoiler to black on top of trunk :-) or better redo to original because the paint did not last on the rubber/plastic ones as you can see.
