Basically as the title suggests, are you able to fit Audi S3 brakes from an 8V model onto an octavia vrs tdi?

 

This is a little bit of a pipe dream at the moment, however I've seen a few sets of S3 calipers and disc sets appearing on ebay and a few other places and with them having the same platform, I wasn't sure whether it would be a plug and play job?

 

I wasn't sure if moving up from the standard 312mm front and 272mm rear and to the 340mm front and 312mm rear would cause any problems for the braking system. I've seen similar things getting done on golf gti / gtds and also standard A3's, but again I don't know if deep in the bowels of the car they have a better master cylinders and other such setups. (can't see that being the case but you never know)

 

I know on slightly older vrs 5e models, they had the 340mm fronts, so I would assume those calipers would be the same. Just be a case of scraping S3 and putting a VRS decal on. It's the rear I've a little more concern for fitment.

 

 

Anybody shed any light on this?

 

 

 

cheers

The 340mm brakes will fit no problem. You will need disks, calipers and dust shields from the vRS.

 

I would also suggest you swap the rears to the 310mm from the S3 / R. It keeps the bias similar to the 312/272 and it feels very planted under braking. Standard bolt on fit.

 

Now that they are fitted to the new vRS 245  2wd factory dust shields and other small parts should be available for the 310mm rears to do the job properly on a 2wd.

 

Question is what are you finding wrong with the 312/272 setup? You will find the car is a little more 'crashy' on 340/310 because of the quite substantial increase in unsprung weight (if you have ever lifted one of those 340s you will appreciate that!)

 

One other 'thinking out of the box' way of improving brakes is to use lightweight Porsche 4-pot calipers on the front combined with Caddy rears on the standard disks. Limits the choice of wheels a bit  but should not be too much of a problem on a vRS. Google "NQSBBK" and be prepared for a long read.

 

Can't see 312/272 being limiting for road use, no matter how hard your brake. If you are going to track the car I would say you probably should be looking at something better than any of the above.

Mine already has them fitted

Is it a 245? Didn't think the 'standard' FL vrs had 310mm rears - happy to be corrected though haven't seen many in the flesh

Unfortunately not. It’s a pre face light diesel!!

 

when I had the brakes changed they confirmed they were the bigger brakes!

Yes some of the earlier Diesels had the same brakes as the Petrol i.e. 340mm front 272mm rear, not that unusual

 

The OP was asking about S3 brakes (as now fitted as standard to the new  FL vRS245) 340mm front and 310mm vented rear

What size do the facelift 230 come with?

 

 

Yea mine has 340 and it’s a diesel. I think up to 2014 maybe 15 had 340,s on the front. Just eBay search for skoda 340mm caliper. There are a brand new set and a used set on there at the moment for around the 200 mark.

Mne was a September 2015 car and has the bigger brakes

AFAIK same as the pre-FL vRS only the 245 is different. 

Diesel 312/272 (brake change came in around MY16) caused quite a lot of discussion!

Petrol 340/272

245 340/310

again AFAIK they all have the same 23.81mm master cylinder used on most things all the way back to the Golf R32

 

The RS3 /TTRS has a bigger (25.40mm) master cylinder but that has to have the bigger servo as well. Lot of work, not really necessary unless going 6-pot

Before I was forced to stop driving this year, I took a trip over to the Isle of Man, as I've been a few times on my bike and wanted to give the car a blast on the island. If you had a bit of a gap between corners, the braking wasn't too bad but you did have to apply a bit of pressure to slow it down a bit.

 

In a few sections, there are a few tight bits and a good bit of fast, slow, fast, slow. From that, you really did have to bury your foot in the firewall.

 

I was wanting to get it prepared for the odd track day and I'd prefer to start by investing a bit of money in the brakes, before I start looking at the suspension (that pipe dream includes coilovers!!!!)

 

I know stock brake pads have a bit to do with that as well, but a bigger diameter disc will allow for bigger surface area on the pads and in theory, allow for them to cool off a bit quicker.

I've seen that page on those porsche calipers, but I'd sooner get a set which was designed for the chassis. Me getting bits and trying to get them to work, especially the brakes, is a recipe for disaster!!

Nothing wrong with that, it is my preference most of the time too, however that kit has been developed by a pretty professional outfit and I would have no problems fitting one of their kits. (as long as you get the original, not one of the copies)

 

From my experience the 340/310 does not feel night and day different to the 312/272, it is the pad area that stops you. There is more on the 340s but not as much as you'd think, the pads are fairly similar size between the two sizes of TRW caliper.  The extra diameter tends to make it more 'grabby' less 'progressive'

 

Bigger diameter disks with single-pot calipers become increasingly 'grabby' and 340mm is about the biggest they use. After that (and a bit before) people use multi-pot. The brembo 4-pot are very progressive but similar overall piston area so no master cyl issues. The Ate calipers from the 8P/R32 feel better, also bolt on but are very heavy.

 

What it does have is a lot more metal to soak the heat generated, but that can be helped by using a pad that works at higher temperatures if you have the luxury of being able to warm them up before use. I would be wary about using high temp pads on the road as it doesn't tend to keep enough heat in them to be effective. A lot of people swap pads for track days.

 

From what you said I would try some better pads in what you have for the track days, it saves a lot of work swapping brakes. If you are still not happy then the 340/310 is the obvious choice, made easier now because the 245 is around. Up to now I don't think the vented 310 rears were fitted to anything not 4wd, not that I have seen or fitted anyway. At least now you can get all parts to bolt on. I would be having a good look at ErWin before spending any money though

Mine came with the 340mm brakes but swapped them out for some ttrs 370mm brake set up. Now it stops with the extra power

Awesome!

 

How much we’re they? Straight not on fit?

You can pick them up from £500 yes bolt straight on but you need the hoses and I'm running  16mm spacers to clear calipers

Thanks for that. I plan on the stage 4 revo so need big brakes. 

 

Ive has a quote on the below. Front and rear 286x22mm full floating discs and 4 pot calipers

Probably just upgrade my disks & pads to drilled & EBC Redstuff, dunno if thats still a good combination nowdays. I've used it before and after running in (which takes quite a while) they stopped great with far less brake dust.

Not really taken with drilled disks TBH good reasons not to use them standard ones work fine, grooved if you have to. If redstuff worked for you before no reason not to do the same

Have you done anything to the rear brakes?

No  nothing but I do want to upgrade to the 310mm rears

I'd probably sort both at the same time.

 

Did you have your suspension done at the same time (or round about the same) to when you had your suspension done? Reason I ask is because I can see you've got it lowered in one form or another and I'd want mine done at the same time, because (deep breath) I would think even with the standard vrs suspension having bigger stronger brakes would cause an increased frontal dive and potentially inducing locking more often. So in theory having stiffer springs would have a greater resistance to it diving down and allowing for a larger braking force to be used without causing the fronts to lock. That's how I read the situation 

 

Or am I barking up the tree?

As I said I don't think there is a lot of difference between the 312/272 and the 340/310 setups in general behaviour, so if the dive is not an issue now it isn't likely to be if you do that upgrade. If you go with a much bigger upgrade at the front (say 370/390 with 4-8 pots) with nothing balancing the back then it may be more noticeable. However to make the most of a much bigger upgrade you would need the bigger 25.40mm master cylinder as fitted to the TTRS and most likely the bigger servo that goes with it.

 

If you are looking for an excuse to do the suspension, then having the car up on the ramp to do brakes is as good as any  KW V3 would be my choice.

If I do upgrade the suspension, I've my eye on the KW ddc kit, as when I took my car in for it's first service, I was able to 'borrow' a new vrs with the ddc as standard and I was very impressed by it. Eco and comfort felt very similar and a little bouncy I thought, but normal I felt soaked up the bumps very well. When put in sport, I was very impressed with how it stiffened up. Ride comfort was affected a bit, but I felt that was attributed to the 19's it was wearing.

 

I do wish that had been an oprion when I ordered my car.........
