Rear brake upgrade

[seangti]

I'm more thinking of doing it 'because I can'

lol, no further justification is required.

Make it happen

Well they were lot closer than I thought, trackday yesterday finished them off.
Will try to source on Monday otherwise I'll have to throw stock gear on.
Chasing some early audi tt leads.
There is a thread on another forum listing rotor sizes for the various models that fit mk4 golfs, I'll post up the details later interesting reading.

Sorry to all who may have thought i was saying a bbk is a waste of money. It does have real benefits in the right circumstances but I'm trying to put the focus on where these real benefits are as opposed to what some people may assume without thinking through the underlying physical factors and limitations.

Rgvlee, that's as good a reason for the upgrade as many of the things we do. Eg last night I used a trim sealant on my tyres and the nut caps.

On a Polo there may not be enough rubber on the road to gain a lot more braking but I would still expect more capable braking with lower pedal pressure
On my Octavia I have 6 piston calipers and 357mm floating rotors - with good rubber ( Goodyear F1A1 225/40/18 ) it certainly brakes significantly harder than a standard Octavia
(In order to get that extra braking I had to get into VCDS and set the anti lock braking to low/late because the car could now brake harder/faster than the onboard computers though was possible)
Around town and during rush hour driving it's less fatiguing because much less brake pressure is required - yet modulation control is still good

I've managed to locate a front and rear set off a 99 TT quattro but unsure if they'd fit. I think that's the 225hp model.

[rgvlee]

OK I've managed to find a set of calipers off a 2000 S3 as well.
What's the best way to ensure any of these will fit? They are all on the otherside of the country so I can't pop in an check before I hand over coin.

[h100vw]

They will fit Lee. You need the calipers and brackets.

[rgvlee]

The 2000 S3
or 99 TT quattro?
or Both?

Both are about the same price.
And yeah I'm onto the calipers and carriers.

When ordering rotors/pads, do you just order them for a 2000 S3?

They are both the same Lee.

If you get pads from GSL/Brakes Direct Matt knows what you need. Otherwise, correct S3 pads.
