You might need some other stuff... I am doing my front end including brakes and the only place I have found the rubber guide bushing is Ellis. Not a bad price, but why didnt FCP or AutohausAZ carry them and / or remind me I might want to replace them when I shopped for and ordered the discs over the phone?
Unavailable from local places (NAPA, Advance, Autozone, O'reilly) at least by my description. Maybe now armed with the part # I can get them soon.

BTW Also need spacers to fit my extra Audi A4 17" Cabrio wheels onto my Passat, having trouble finding true hubcentric with lug bolts for a reasonable price. Need 5mm front and 10 back (wanted all four 8mm but that makes them even harder to find.
Yes bigger wheels do not automatically fit - front tires rub on UCAs and rears on the inside fenderwells.

If both center bores are the same hubcentric spacers has to be minimum 15 mm or so. If they are not PM me.

Default +1; smallest true hubcentric I know of is 12mm

in one flavor of the H&R's I use. Otherwise 15 mm as Misha says. As you get down to 12, exactly how they taper the angled area of the hub becomes critical with only ½" (12- mm) to work. At less than that, and especially at 5 and 8mm all you are really buying are essentially ginormous washers with one center hole and 5 bolt holes in them.

Thanks Misha; to avoid hijacking this thread I've started a new one...

And from what I've read all modern VW & Audi wheels are 57.1 mm hub.

Default + 1 on the rubber guide bushing at higher miles

Kind of an obscure brake part, but available. I have a set on hand for my next full rotor and pad swap. I would have to look at package again, but I think they may come in a set of two--enough for each caliper. Starting to realize a very slight chatter noise I get when brakes are cold and pulling to (only) first stop may ultimately connect to those bushings--its not the pads or rotor tarnish form what I can tell.

Also going to do front hoses (with OE/OES) on my next go around since they will be 10 years old from build/approx. manufacture date by then.

Default Actually...there was a PITA Audi hub center change to be careful about

Went form 57.1 to 66.1. Happened from D3 to D4, and in parallel from C6 to C7 and B7 to B8. All A5, Q5 and A7 based ones are the newer since they go off the B8 and C7 bodies. The Q7 is the Touareg/Cayenne one off with the larger bolt pattern, and the TT went with the VW based transverse stuff IIRC, at least the first gen. one--I always ignore those in wheel related searches/fitments.

Net, you have to be careful on whether you have the "classic" like D3's or the new style like D4's, etc. You can use a concentric hub ring to adapt a newer wheel--some have done with the D4/S7 20" wheels that are pretty easy to find in recent years--but on spacers just be sure to get the older 57 mm classic hub center style.

Great, another variable.
Good news: may make thinner hubcentric spacers possible
Bad news: Probably need to be cu$tom made. Although I do have some friends who are machinsts... hmmm (gets calipers out)

NICE!

even getting the same parts, using www.audipartsusa.com, even after the cost of shipping, was less $200+

and only $250 for labor.


thanks again Mishar.

I got Brembo from FCP Euro and TRW/Textar pads. Same p/n is OE on Gallardo, so ok with me. They were cheapest after a looooong search.

Oh I see Misha has got you squared away.

Rotors and pads look closer to 950.00 for OE at Audipartsusa.
