Today I.....

Today I finally summoned the courage to exchange my climate buttons with the ones from an A4 unit I got last year. In the process I thought I'll destroy the fascia a few times but....all's well that ends well!

Today I had new discs, pads, callipers, drums and shoes fitted...and, maybe controversially, have painted them...
My justifications for this are as follows:
1. I am 44 and not really bothered what people think of me anymore ?
2. This is the first car I have owned where I have done anything other than ‘factory’ changes to it (my alloys are now a non Audi colour)
And 3: I like the colour!

I like, but 'apparently' you don't care what I think ? Even so, for what it's worth, I think it looks great.
 
Today I... Examined the front wishbones for excess/ terminal rot as I have a later car with pressed steel version. I had already put a pair of lemforders in forged in my Autodoc basket anticipating an imminent replacement. However, pleasantly surprised that a good wire brush and they seem serviceable for the mid- term at least. A couple of applications of Bilt Hamer rust converter today and a couple rattle can coats of chassis paint tomorrow and I can spend the £180 elsewhere... on the A2 obvs!
 
Version.... 3? Of the 165mm speaker adapters are close to done. Need to confirm they will fit correctly before I make some more - there's lots of movement possible, I just don't have standard door cards so cannot test. Need a volunteer.... the ground zero 165s fit perfectly, even with their crossover attached to the terminals. Pencil for scale. The skin also flexes when not screwed in, so there's some slightly oversize holes for the screws. The skin is also seriously damped.

You have me salivating here, very interested to know more!

Although i've never heard of these speakers or indeed even knew about them, they use the same cone technology that was pioneered by Monitor Audio back in the early nineties. Very much looking forward to seeing this project progress.

Will these be comparable with the A2 Bose system?

I had a problem with these two items flash rusting, it’s been very humid recently. They went back in to convert the orange dusty look. Came out black, dried with a towel, into the oven to fully dry, wire brushed then etch primed.

They really do look good.

I remember trying acid dipping some panels in (I think) citric acid which has a few advantages. What was amazing though was the flash-rust speed: literally as you withdrew the panel. I can't remember how I resolved it (I know I did), but remember the frustration as they were rare panels, customer owned and the blaster had already made a poor job, hence trying to recover the situation.

I now use phosphoric acid (40/60 with tap water) and that leaves a protective coating (iron phosphate possibly??). It's fantastic stuff.

Available on eBay I buy the 95% pure I think. Works well. I'm spraying it onto panels and then wipe off excess later on, evaporate this off the cloth which ends up on the bonfire. Not sure how you'd dispose of it as a fluid though, which was the advantage of citric.

Good tip thank you, I have some phosphoric acid. I'll dilute some and use it as a dip after electrolytic.

I would expect better bass. They are also only 3 ohm, so a nice load for most amps and they were cheaper (and more available) than the Etons I was originally looking at. Titanium tweeter shouldn't be too harsh, bit will have to listen.
The fitting is important now. Depth-wise we are good, but the position of the driver vs. the hole in the door card is important.
Hope to have a first set of adapters for a reasonable price available this side of the summer. Material is 15mm ply - MDF is too susceptible to water for my liking - and I need to still glue, seal and paint before they are "done".
