Otherwise, I suggest speaking to either Jasmine PorschaLink at http://www.jasmine-motorsport.co.uk/shop/index.htm or
Type 911 at http://www.type-911.co.uk/
Thanks I will PM Corey as he never got back to me when I asked recently. His input would be useful

scillyisles wrote: There are several reasons that a two-piece floating disc assembly is of benefit. First, by using an aluminum bell for the hub section of the disc it saves a great deal of weight. Since this is both rotating and unsprung, it benefits the acceleration, braking, and handling of the vehicle. Secondly, it is better able to handle the large temperature changes that a brake disc experiences. During severe use, temperature variances become present in a one-piece disc and generally cause warping of the disc. This not only results in vibration of the vehicle, and pulsing of the brake pedal, but also pushes the pistons farther away from the disc. In a two-piece floating disc assembly, the iron disc heats up more uniformly, and the controlled float which is present allows for the differential expansion of the very hot brake disc, and the relatively cool aluminum bell. This allows the disc to be used under severe conditions without having a detrimental effect.

The Audi upgraded brakes for the RS2 consist of a fixed caliper (produced by Brembo) that is secured rigidly to the axle assembly and has opposing pistons that force the pads against the disc. Fixed discs are designed to operate best with a sliding or floating caliper which has pistons on only one side of the disc. Therefore, when the caliper acts, it must slide or float in order to bring the pad on the opposite side in contact with the disc. Nearly all original equipment calipers are of the floating type. In the upgraded Audi brake system with fixed calipers, not only is the mounting much more rigid, but the stiffness of the caliper itself is greatly increased. This manifests itself in enhanced braking performance, pedal feel, and pad wear.
Good points. Some bad statements from me in the last post... I blame it on the unknown lanuage.. :) The real question is it worth the money..

This one-piece dics is from 1994 911 3.6 Turbo, and so is the "Big Red" caliper. I belive they also has the fixed caliper, and hopefully enough braking performance! :)

In the end I belive we agree in this manner, but I'm willing to bet you will be as happy with the one-piece disc as the other disc.. :)
At least I am.

The 2 piece Porsche disc (322x32) cross drilled disc is the 993.351.045 and 993.351.046, the 965 version is exactly the same rotor but it is a 1 piece disc and has a different offset, we use this disc with our GT3 upgrade on the RS2.

For the backing plates speak to Brian at Jasmine and say I sent you.

I have the big red upgrade on my car and need to replace the discs and pads.

From the above discussions, does this mean I could order the 2 piece Porsche disc (322x32) cross drilled discs 993-351-045 and 993-351-046 together with the front brake pads 993-351-949-00 from a Porsche specialist?

For the rear can I order pads 965-352-939-04 from the Porsche specialist, then get rear discs direct from Audi?

Or am I best just biting the expensive bullet and getting from Audi direct?

Audi 'did a number' on the RS2. No porsche parts are exact replacements. If you want my view. Order Audi. I have spent ages trying to confirm porsche bits are compatable but have failed to convince myself they are. In this age of lack of first hand experience availiable at audi dealesr/independents its easier & less hassle.

audi is too expensive for me to buy these discs directly from them.
i recently bought my one piece drilled discs from ultimot.de for 520euro delivered and i havent received them yet,but having bought the rear ones from them in the past(they were not original but drilled),the discs are very good and much cheaper.

Thanks. Oh well, looks like Audi it is then.

Anyone have the right Audi part numbers for the Big Red front discs and pads as well as the standard rear discs and pads?

Try VagParts, they have a kit of goodies for the big reds that works out cheaper than the regular ones from either themselves or Audi.

Whatever you do, don't go to VagParts.

No, I'm sorry to hear they've gone under, they were always helpful, their prices were good and delivery was quick. I'm even sorrier to hear that this list of ingredients isn't a recipe for success.

Why, oh, why didn't I put a full set of brakes aside? 20:20 hindsight and all that.

Thanks for the help guys. I'll be going down the Audi route, but before I do does anyone have the Audi part numbers for the big red front discs & pads, and the stock rear discs & pads?

Cheers,
Neal

Folks, thought I'd share these Audi part numbers for ref:

'Big Red' fronts
Pads 8A0698151G
Insulators 4x 8A0615231D
322 x 32 cross drilled front discs Left 8A0615283, Right 8A0615284
NOTE: these discs are special order 3-5 days

Cross drilled rears
Rear pads 8A0698451B
Insulators 4x 8A0615231B & 4x 8A0615231C
Rear discs 2x 8A0615601D

Do you think I could I get away without buying the insulators or is that cost cutting too much?

you need the insulators,otherwise your disc pads may touch the discs when moving and the brakes will squeel.

again i believe i would never get them from audi.Its ridiculus money for something that will wear out anyway.I got the porsche ones,and payed 530euro including shipping for the fronts drilled 322x32

There is a reason everyone wants a Porsche.
