Well, done quite a lot of work on the Polo this weekend.
Since I'm planning to 'tickle' the engine, I wanted to get some better braking power. I've got the old VWI system now (massive brake-discs) and wanted to go for the VWII system (vented brake discs), so I got myself a good pair of second-handed VWII brake callipers
Overhauled them last saturday, cleaned out the pod/cilinder:
New rubber closing ring inside the cilinder, lubricated with brakecilindrepaste:
And a new rubber dustcap between the cilinder and the piston (which I also cleaned thorouhgly and lubricated with the paste):
And now got myself a almost brandnew, perfectly working pair of braking callipers, width enough for the vented brake discs (just need to paint them red again):
Planning to get a new set of Zimmermann drilled (and of course vented) brake discs, and hopefully, if I've got enough cash) a pair of Ferodo DS2000 brake pads. Surely it will then brake like a virgin spottin' a red light district
Also got around to "improve" my doorspeakers yesterday. Since the original VW doorholders for the woofers of my componentset aren't that heavy (and therefor shake about with the woofers, which fucks up the soundquality) I made it heavier with what we Dutch call "bitumen", it's like lead which you can stick on and mold into any corner after you heated it up, superstuff!
Here's before:
And after:

Filled the speakerhole with special stuffing for speakers.
And covered it all up in the lead, making a sort of "roof" for any water coming into the door, so it can't reach the speaker and short-circuit it or something:
Haven't got pics of the front look, but that's also covered with the sticky lead ("bitumen"), made the speakerholder 6 times as heavy as it was

that bastard won't be shacking that fast any more
Tested it, and even without the doorpanels on (didn't get around to do it) it already sounded a lot better, much better sound quality, no more little rattles on the bass
