VWR brakes, very disappointed, but hoping to feel better !

Nice... shame about the silly wheels!

[Gti_Mad]

I agree with u rich the brakes are  but those rims are

Carrera, do you have TT arms and/or S3 spindles ? If yes, they can't possibly fit as they've been designed for the standard GTI arms & spindles (although I can't imagine them using these heavy iron parts on their racing cars). There would be 2 problems :

1) S3/R32 brakes do fit both GTI & S3 spindle because the caliper bracket mounts on the outside face of the spindle wich has the same distance related to the disc mounting point on the hub (wheel bearing). However, as the aftermarket caliper brackets mount on the inside face of the spindle, the S3 spindle is 16mm thicker than GTI one (33m for S3 and 17mm for GTI) wich means new brackets (16mm elongated) need to be made. Dave is doing these for my Ap Racing brakes as we speak !
2) The tt arms and ball joints will also interfere with the lower side of the brackets so they need to be modified there also

And point 2 is due to the fact that the AP's is an Radial mounted calipers right?

Guys, tks

I have TT bottom arms, stock hubs. I want something that involves no additional modifications and simply bolts on to the current arrangements. Are we saying that AP 330/28 four or six pot won't work ?

I really don't want to be shopping around for parts, worrying about fitment etc, etc. There must be something from AP/Brembo/Alcon that is a bolt on that does not move the inner face in by some 8mm and clears ?

If not I will try pads only and replace discs 

[fuscobal]

Hard to say if they work or not. With OEm hubs, point 1) will be acomplished but not 2). Only DaveB could help in this respect !

[DaveB@Vagbremtechnic]

AP do a kit for an S3, you need to be the queen to afford it.

My info is that only three sets exist one of which is on a shelf somewhere, they quote 28 days delivery.

Alternatively 996 turbo calipers, the cupra has S3 hubs and there's a few guys with this setup. The S3 also isn't endowed with the biggest of master cylinders so the big split in piston sizes of the 996tt caliper helps with the pedal.

You could spend a lot of cash and go backwards quickly

Alcon 6-pot 365mm MKII TT kit?

An 18" TT wheel goes straight over them, but then they have a more generous offset.

Bolt on, pretty much the best you can get.... but expensive. Speak to EARS in Macclesfield for the best price, but be prepared to punt £2k upwards.

what is the point of fitting the s3 arms to have nothing fit  you wont even be able to tell if they have made a change to the car  and if you say you  can its in your head  leave it alone fit good coilovers,walk,arbs and fit the brakes job done

[Hedge]

S3 Arms and Hubs are fine it's the TT ones that seem to cause the problems. 

[Carrera2RS]

Some good progress,

I have spoken to VWR, they are considering a solution and will come back to me.

It's worth pointing out they built the calipers the non usual way round to improve pad life for a road car. The 'normal' race way round will provide better 'bite' and braking, but at the expense of pad life.

If this is not a goer, then I will look at your helpful suggestions DaveB thanks for the help

Matt, I have TT arms not S3, Hubs are stock ?

[fuscobal]

Mat, I've replaced the TT arms first and felt a good cornering improvement and then the S3 hubs and the comfort improved !?!? Believe me, this was not only in my mind and I don't fully understand it even now. Because the hub is just a lighter piece of metal it can't influence comfort by itself but the only logical explanation for me is the lower weight of the hub helped the damper work better since the ride is much less crashier now !

Somebody fooked up, one way fits all Im afraid. Small piston bites first, bigger subsequent piston bites second. From leon Cupra R to Red Bull F1 Car, unless VWR know better than AP Racing who manufacture F1 brakes.

You're being blagged because of a school boy error - you'd feel better if they just laughed and coughed for it or at least tried to tell you they were off an A4 which does have lagging not leading brakes...............
