Ah, cool responses!
The only reason I'm interested in going with the 55 watt ballasts on the main low beams is the amazing amount of light it produces in all the other vehicles, in cluding my motorcycle that I've put them into. (And so far, no scatter, or problems with other vehicles flashing me if they are set at the right level.)
I got the light kits in, and there is no connection wire from the headlamp supply line, to the ballast for the main low beam light. (I have not looked to see if the plug is the same, but I doubt it.) I might have to get the company to send the harnes/plug, or scavange a set from another kit that my neighbor has and is not using. (We upgraded his ballasts to the 55 watt "raptor" version from the "slim line" that were not always lighting up correctly when hot.)
The adapter to fit the stock low beams on the USDM lights appears very well made, and should locate the bulb exactly like stock.
As for the fog lights, I don't get fog here in Idaho much, if ever, so I only use them for extra fill light, and it's wider, so it aids in turning corners in the dark country roads around here. (And helps to light up that deer standing on the side of the road that's about to jump out and meet you at the last moment...)
I'm looking to wire my fogs so they will remain on when switched on, regardless of high beam use, and be able to put them on when the "running lights" are on, so as Daylight running lights too.
The US version does not have the small lamp, or "park lamp" on the EU version, just the high/low and park/turn signal bulb.
Now, any tips on how to remove the lamps?
Or easy method to remove the fogs? I'd like to remove all the lamps, and clean up the lenses, refinish or polish them to like new condition. (The fogs are very pitted by sand/gravel that is common around here in the winter, and this car started it's life in Maine, so I'm sure they have had snow/gravel/sand on the road there as well as salt. (Dang, it corrodes everything.)
ON a more positive note, my new rims and tires arrived from TireRack!
I've put the 20" 5 spoke's with the 275/30 20's on the 2001 S8 that I had on my 2004 A8L before, and it's a tight fit. (And two of them have slight bends in the rim, very minor, can't tell if they are on back, but I know, and I can feel the vibration, and it bugs me, especially if they are up front as I have them now. The tires are more than 70% worn out, and new tires are over 1280.00 alone, and new rims and tires were under 1500.00 so a no brainer! (And I can sell the existing ones to someone for 650.00/550.00 easy as there is at least another summer on these tires.) These new ones are 20" as well, but only 255/35 20's with a 27" diameter, so the speedo should be very close to correct. The 275's are listed at 27.6, so better fuel economy in theory, and lower RPM at speed, but less "go" off the line.
I will miss the extra ground clearance however.
I'll have to throw up some photos when I get a chance.
