« on: January 06, 2005, 07:40:26 PM »
Can any one help me figure out if a set of Audi S8 brakes will fit on my B5.5.

The front brakes are 13 inch rotors and the rears are 11 inch.  The calipers are Brembo 4 piston.

The kit is a direct fir on the B5 S4 and I am hoping it will fit my car.  I just need to know where to look for fitment info.  I would normally look at ClubB5 for this info, but recently the site is harder and harder to use.

TIA -

Negatory.  Not compatible.  Why do you want big brakes?
If it's to stop faster, just get some better pads and sticky rubber.  If you're concerned about fade/heat resistance you might try A8 rotors with your current calipers or Stoptechs.

Thanks for the info Pat.  Where did you find the fitment specs, not that I do not believe you, I just would like to know for future use, so I do not have to post every time.

I want brakes that will be less susceptable (sp) to fade and have better heat disapation.  I realize that stopping power is a total effect comprised of heat disapation, pad resistance, friction and tire contact - not just the size of the brakes.

I was offered a complete S8 kit - brembo calipers, Stasis rotors, pads, and lines (front & rear) - for a good price and saw this as a possible solution.

I didn't find fitment specs.  I know the W8 and S8 share brakes, and the W8 brakes are way different than ours.
That would be a great kit to have for sure, but it's just a shame it doesn't fit our cars.  If you want improved fade resistance, the first step would be pads.  Then, if that's not enough, put on some A8 rotors, TT carriers and keep your stock calipers.  That is likely the best value out there for brake improvement for our cars.  Very popular.  I can't ever imagine needing anything more for my car's needs.  I usally track it a few times a year, too.  Keep in mind the more power and weight you have the better brakes you'll need.  Our cars weigh about the same, and my car now generates 245 hp and 295 ft-lbs of torque on 91 octane.  If you have your heart set on a BBK, go Stoptech and call it a day.

I will have to look into that set up.  Thanks.

The thing that got me thinking was the fact that these are comming of an B5 S4 in the midwest and I thought the fitment would work.

I agree faster car = NEED for better stopping ability.

Good thinking, Randy.  Unfortunately S4 brakes use the HP-2 caliper, which is different than ours.

I've noticed that with BBK's, the diameter is larger, but the rotor surface is not that much larger. I know this is not the case in all cars, but it doesn't seem to me that a larger stopping surface si what you'd want and not necessarily larger diameter.

I understand your logic, JR, but a larger diameter is every bit as important as pad area (maybe more).  It's all leverage, baby!

Cool. I gotcha. You should to a brake write-up so we all don't have to keep asking you questions :wink:

isn't it not just pad area, but swept area on the rotor?
sorry if I am just adding to the confusion here.

Also wondering how that S8 setup differs from what I have on the allroad.  Hmmm.  Jon?  Are the HP-2s the ones used on the early allroads or the more recent ones?

Andrew, I'm not sure, but I think the rotors are SLIGHTLY different.  J-Dawg can confirm this.  Drop him a line.

Randy, the S8/A8 brakes may not be a direct fit, but I would post over on CB5 anyway as someone may have taken the time to do this and may have the necessary information for you.

Anything is possible.

Randy,

What is your current setup that you are unhappy with?

OEM, so I guess improvement should be attainable. :wink:

I will post on CB5 and see what I get.

The kit also comes with all the mounting hardware to bolt up to the car.  So if this will not work for me, maybe some one with an S4 will grab it, I know it works on that car. :cry:

Hmmm...I wish I could help you there, but I know nothing about Skodas. I'm sure someone will pipe up though.

I would cautiously say no, but anything is possible.  I think the problem is with the caliper carriers and the mounting points for them.

there's nothing for you to learn..
it is actually a passat long-version 1.8t longitude,
AWT motor etc etc..
http://www.skoda-superb.com

w8brakes dont fit passat 1.8t either..
we are trying to figure out what needs to be done in order to fit..

colorado,
caliper carriers and mounting points you say
if this is all, then most probably we can create our own to fit..

thank you guyz

if someone has any idea he is more than welcome to speak it.

as all this goes on, I will inform you of the possible success or failure..

i think w8 brakes are one of the best solutions for our cars..

I would like to know about your possible W8 brake upgrade...that'll be cool. Keep us informed!
