This weekend I changed the rear differential fluid to Liqi-moly. Looked like the original fluid at 144,xxx miles. Will do the front and center diff next.
Removed the non-hubcentric front spacers as they definitely threw the wheels off balance. Almost lost a finger on that one...
Add a small cheap plate amp in the rear on a JL Audio ported 8" sub. Sounds MUCH better but I'm already past it and going to drop in my Image Dynamics 12" and a real amp. This all started because the front image was shifted to the right. So I cleaned the tuner/amp connectors and the factory radio came back to life.. and it's actually not bad at all... Except that 5" sub in the spare tire.. I took the speaker lead from there, ran it to the low-z input on the plate amp and dang if it didn't sound better! Audi even provided the fuse holder for the amp power!
Took it on a 16 hour drive yesterday.. Left at 0200(2am) and returned at 2000(8pm). It drove beautifully.. However I confirmed the vibration was the non-hubcentric spacers (removed, see finger picture above) and the mid shaft bearing support.. Ordered and received the JXB Performance support replacement but did not feel like installing it today... I hope to get it done during the week or next weekend and report back.
Oh and the IE flash dongle arrived... But I will hold off flashing the ECU until the mid shaft support is changed.. Last thing I need is MORE torque on it right now..
Thank you! I purchased these 18" Audi wheels from Craigslist locally. I do not know the name, what I do know It wasn't supposed to fit MeinVagen because the borehole was much smaller. I saw a video on youtube and i used a router with a bit a simply cut the hole bigger. They came off an A6
Audi used 57.1mm center bore, until the release of the B8 vehicles starting in late 2007 with a 66.5mm. Then D4 (A8) and C7 (A6/A7) changed to the new bore after that. So if those were A6 57.1mm bore wheels, they must have come from a C5 or C6.
If we save your image, cut out the wheel, drop that into google image search (lens.google.com), we get back hits showing 4F0 601 025 CD from the C6 A6. 18x8.0 et48. Compared to the B8 A4 stock 18" of 18x8.0 et47. Color code is 8Z8 which seems to translate to "brilliant silver". Apparently, that's also what my B8.0 A4 avant stock 5-spoke wheels are. Mein's are a bit shinier than mine these days. :-)
While Audi has other 5-V-spoke designs, it doesn't seem Audi carried that specific design (5-spoke antlers design :-) into the 66.5 era.
That's pretty much standard fare, downpipe requires stage 2 because the stage 1 is intended to be used with the stock hardware to retain stock emissions compliance. Stage 2 is where the cat management is disabled because it's expecting non-stock, non-compliant kit, ie a "high flow downpipe".

While I completely agree and understand the fundamentals, IE did a horrible job on their customer support.
