Evening guys.
As I'm on an upgrade session I was going to have another go at the S4 rear 300mm disc upgrade onto my old bus.
On closer web search a few sets are for sale all in similar rough condition with almost all in need of total rebuilds etc and for the stupid "S4 /RS4 " prices that sellers seem to think are acceptable.
Anyway, noticed a set on the dreaded FB market place, not cheap but not as much as some on offer, pic looked ideal , well until on closer questioning the pic the seller is showing is not his set.
The pics of the items he is selling are not even close condition wise, and as for his description " like new" , i think he should be had up for miselling twice over, what are some people like.

If some poor unsuspecting guy buys these based on the pic he has listed and they are posted aswell so no way of knowing you'll b getting something different, well i'd be issed off to put it mildly.
Why do people do this sort of thing, arghhhhh it really gets my back up.

Rant over , i wont be going to him that's for sure but i may just get some new carriers and a pair of M-tech 300mm vented discs and wack them on.

I always look for subtle (and massive obvious red flags ) clues in adverts when buying online ..I’d run a mile from that listing

Isn't the S4 rear setup, just larger discs, and carriers with a greater offset? Thought about doing it on mine when i did the 18z's to finish the job, but couldn't justify the expense fore the calipers/carriers

To be Honest Alex the S4 B7 rear conversion is a lot of money for what it is, well it's not if sellers didn't ramp up prices of the used parts.
I've said it before and it still applies, a lot of sellers see RS & S parts as a licence to print money, a lot of it is just way overly priced given most used kit is well used and pretty shabby to say the least.
I don't have an issue with cost as long as it's worth it, i still don't think the s4 rears are worth the cost given the parts required.

I may just wack on some 3.0TDI 300mm non vented discs and decent pads , a fraction of the s4 conversion and just as good overall effect .

I've just ordered some now.
300mm discs and better pads, just over £80 to get 300mm setup on the rears , maynot be vented but then I'm not racing .

yep, you'll have the same rear calipers as mine. :thumbs up:
a pair of 300mm 3.0tdi discs and pads came to £76.00 inc del with some promo discount, it's a no brainer really, it will balance up the front to rear a bias bit more now without spending £450
so i have £374 to spend on other b7 goodies now.... yea :yahoo::yes:

On our buses the OE rears are , non vented - Diameter: 288 Thickness: 12 Minimum Thickness: 10 Height: 36 Bore Diameter: 68 Studs: 5
the closest non vented 300mm setup to match these but still fit the OE caliper setup is, non vented - Diameter: 300 Thickness: 12 Minimum Thickness: 10 Height: 36 Bore Diameter: 68 Studs: 5
they are standard fitment on several platforms but i choose these from, an A4 Avant 3.0TDi Quattro 04/08 -08/12
