Avant Rear Brake Upgrade - Rear Brake Porn by request

[S2central.net]

It DOES just bolt on - ridiculous I know but heres the proof on my Coupe - you'd almost think the man at Ingolstadat that designed the 8E0 rear brakes had some S2 owning friends !!!

As stated - handbrake is the only niggle on the Coupe cos of location but its easy resolved on the Avant & Sedan.

So your using calipers and discs from a b7? Are you using a bracket, hard to believe that it just bolts on.

[S2central.net]

I told you this would be easy on the S2 Avant (and Sedan) - tis the '8E0' conversion I did on my Coupe earlier this year. I'll have to dig out a linky for it...

Differences to Bens work and mine as follows - to best of knowledge -

On the Avant/Sedan with its handbrake layout you can use the 8E0 calipers and therefore retain the disc at 300mm. On the Coupe, the handbrake is problematic with the 8E0 caliper so you need to do things a bit differently - ie use RR/S6 rear calipers, reduce disk diameter to 280mm and use A8/S8 carriers for the 280mm disc.

I never bothered with the backplates / splash shields - hate them really so can't comment on that.

On the Avant/Sedan its all easier cos it all bolts on - the only complexity is handbrake as Ben discussed but it is not a showstopper like the Coupe.

Oh I also see that Ben used the later black coloured calipers - I had the silver ones - then sold to the mighty Ross for his beast.

I still need to get my 996 monos on the front to balance out this combo - all of which could just squeeze into 16" Avus if you wanted - I still have them for winter rubber.

Hi Ben

Any chance of a shopping list for this conversion with part numbers and likely cost.

Will it fit under standard 16" Avus wheels?

Cheers

Question is why would you want this under 16" alloys on the rear?

As it would seriously effect brake balance, better of uprgade the fronts 1st as this does the majority of braking.

@Ross,

Mainly my handling and stopping power, although we may have a couple of tweaks to the engine up our sleeves. Only time (and the US postal service ) will tell.

Ben

[Ross]

@Ben, is this because of your stellar handling + stopping mods or is there a plan for more power? I can't afford anything more on the car this year so be nice!

@Jamo, wait i will, but by 2009 I'll probably be on the next evolution of my engine

Incidentally the midlands seems a very strong hold for the Avants - soon we'll have a very good stronghold here in the south, but i feel a very strong rift in the force around the banbury area And then... Somerset will be our final frontier

Nice work Ben, glad to see you're never satisfied and pushing things forward, 335mm next... you fecking nutter!

Is there anything similar to fit a coupe? Will the B5 S4 stuff fit?

You should all be quaking in your boots... the Alpinweiss is going up the strip!

with Jamo backing down i need some competition

Just you f*cking wait you!

[s2avant]

Ross,

On the quarter mile you'll eat me for breakfast with your engine mods

On the track at Audi Driver later on this year might be another matter :mischeif:

Hey - at least you can see the rear brakes through the wheels now... I think that looks awesome! Just to clarify - this is the brake upgrade as per Paul Nugent's thread, right?

Corey, what do you think? There's a big box in the back of my avant... :mischeif:

Ben, top job been waiting for this thread for ages, can't wait to see your beast at GTi Besides, with Jamo backing down i need some competition

Found this, might be a great next step for all you brake pornographers

[dan_b]

With that much disc at the rear, have you found any issues with rears locking/ general brake balance vs. the admittedly enormous fronts you have?

Just wondered also, might there be issues of never being able to generate enough heat in the rears? What pad are you using at the back, I'd suggest one that works best from cold...

All this brake p*rn is making me think I need to investigate upgrades on my V6 2003 A4. Don't suppose anyone has any tips for me on that?

[UR-S4]

WARNING pull out red arming pin before use !!!!!!!!!!!! p.s some slight issues with handbrake cable attachment (caliper lever),im working on it!!!

[NEO]

Why wouldn't it work on coupé? WHat would differ? Only handbrake? Can't be impossible to solve.

I hate myself for not buyin a couple of RS4-b7 rear brakes when I had the chanse.

Good write-up Ben. Shame it's not much use to Coupé owners.

Yes. They would look a little small, if they were front brakes.

BTW, how is your master cylinder coping with all this modification?
