need disc part number

[RIX]

since we have ****ti rules in Denmark, fore upgrading i have an idea about using audi tt calipers(312*25),since you can mount our calipers(s2) on the vr6 and the like´s,i have look throu the old treads and read there is a us spec A8 disc 312*25 could some provide me the part number please.
i now it´s not as good as the porsche caliper´s but i haven´t got 2000 euro´s fore at kit that will pass danish mot(tüv approved),so i will chaet if i can(safeli that is).

Thanks in advance

RIX, don't use 25mm thick discs, they'll be about as bad as they are now. You need a thicker disc, 30 or 32mm is a minimum.

HTH,

i think the bigger disc will help a little,i don´t think the caliper from the tt will handle the 30mm,but when i get my hands on a loner i will tjek,i was looking on ebay.de last night,there was one person that said that u can use the hp2 caliper with 314*30 or 323*30 on the s2 is that correkt,cause i have always heard that you can´t use that caliper.but last year i owen an s3 2002 model for 6 month that weight´s 1588 kilo´s,my avant weight´s 1560 kilo´s,so my first idea should work,i had no problem´s with fading on the s3,and that was with oe disc and pads,i would use zimmerman/ate and ferrodo pads,
any more input will be happy resivede.
Thanks for the input so fare

i have look at nerly all treads in the brakes forum

[Mikes2]

the HP2 caliper will not fit the S2 strut without major work. The bolt holes on the HP2 caliper are much further apart

[RIX]

okey thanks,then it´s back to my tt caliper´s and a8 us disc 312*25,plan again.

a little up date,i have had look at the disc from the a6 avant the one with the 10 holes,and the hat height(ithink it´s called that) is about 9mm smaller,so it´s not a direkt bolt on(9mm spacers for the carier and it will work with tt callipers),but i can now make an extra bracket so that our 2 piston calipers can be mounted with the disc,my next move is to tjek the part number suppliede above,and if it´s the same as the disc i have messured,the ill make the bracket for both ithink,and the see what i can afford,but my idea is looking good so far,and iknow that mihnea and others say that 25mm is too thin but when i get an idea then ill have to try it out :mischeif: ,ill post my progress,i will not make alot before iget my sommer wheels on,couse a the moment i only got 15 winters on,but next year ill have referbished 16¨ passat alu (9spoke) for winter(being cleaned as we speak,and painted during the summer in titanium/gray metalic) .
fouther input is welcome,ore if you have questions.
Best Regards
