I've always found getting hold of DaveB virtually impossible.

 

Doesn't the Mk3 VRS have 340 mm discs on the front? 

 

You need to consider that while the NQSBBK uses a 312 mm disc it needs more clearance around the front face of the disc. While you "could" fit a 16" wheel over the NQSBBK I think you'll have trouble finding some that have enough clearance behind the spokes. You could solve this with spacers, but I personally don't like them. You'll need 10 mm + of spacing each side I would think.

 

The 340 mm set up will take a 17" minimum wheel, but should fit almost all Skoda wheels without the need for spacers. 

Just my opinion.

Yes I could go down the route of getting stock mk3 VRS disks pads and calipers if they would fit on the hubs but I thought the nqsbbk would be cheaper both initially and in the long run and maybe slightly better braking.

I don't plan to run anything less than the stock 7x17 but thought that they would have the face clearance as fit on the yeti seemed ok from what I read

May have to get a clearance distance from the face of the disk to compare to my 17"s and price up a VRS set up

The trouble with going to the 340mm vRS Mk3 setup is that it's very heavy & you are still dealing with a very basic single piston sliding caliper.

 

Ideally, if you can get one of the good folk in this thread to do a template of the hub/rotor/caliper profile & then check it against your existing wheels.

The trouble with going to the 340mm vRS Mk3 setup is that it's very heavy & you are still dealing with a very basic single piston sliding caliper.

 

That was my thoughts to start with, but I would feel a bit happier if someone with a MK3 had tried it as there may be differences I haven't thought of and dimensions from a different machine might sit differently from the hub face. Have asked the q on the O3 forum but no takers

 

Only advantage with stock VRS setup is it would not stand out too much (with non painted calipers) wheras the 4-pots are quite obvious which I don't really want, although left unfinished they are not too bad.

 

Just want to sharpen up the braking a bit as the you can load up a combi quite well and it would be good to have a bit more without going OTT

I am going with the Boxster S calipers which are sitting in my shed waiting to be refurbished. My plan is to use the rotors from an S4 (321 x 30mm) and Apikol steel carriers. Apikol state the disks will require rotor centering rings which I will need to source somewhere once I find out what they are . . . If anyone has done this I would be dead keen to learn from them.

I did look at cheaper carriers going on fleabay for 330 x 28 mm disks but those rotors are heavy and IMO the alloy carriers might not be strong enough, not to mention that the brakes would then probably not clear 17 inch wheels for winter use. I will think about two-piece rotors later - JHM seem to do nice ones that fit as stock replacement (on an Audi).

I think the stock vRS brakes are ok at best but a bit of a lucky dip at times regarding how much pedal is going to be required. I will accept though that I could have fitted better pads.

Upgrade your pads, rotors , brake fluid and fit some braided lines.   QF A1RM or Ferodo DS2500 or similar that can take some heat.  Upgrade the rotors to a plain face (I'm not a fan of slots or holes on a daily) DBA T3 or similar or go to a hatted rotor.  Change the brake fluid to something that meets the VW 501.14 spec.  Pentosin have something in their line.

 

Keep in mind that  1.9tdi Kombis only had the jam pot brakes & they can be loaded up just as much.  The 312mm system is a reasonable package if you put some thought into parts selection

Although I would do lines, pads and fluid to ATE dot 4 (old blue) when I did the calipers as a matter of course I'm not sure these make the kind of difference I am looking for on their own.

The car is new so if it doesn't have 501.14 I would be asking questions, I don't think that braided lines have a great difference over modern lines in my experience and I am wary about going too hot on the pads as it always compromises cold braking. I do lots of short trips so I need braking from cold.

Whilst I always make sure my trailer will out brake the car I do make use of the towing capacity on occasion and a progressive brake is always nice to have over a grabby single pot no matter how big the single pot is

I just do not like the feel of the pedal and have had a few 4pot setups in the past and like the feel of the 2 sized piston combination. I think it would work very well on this but I am struggling to find anyone that has done this on the Octy3/mk7

I would like to know if anyone has this setup and could measure how far out from the disk face these calipers come as if they do not fit with the standard wheels I have it is a non starter for me.

what calliper carriers are people using for the 968/996 Porsche callipers using the standard 312mm disks?

Cheers

Generally the best regarded carriers are made by Dave at Vagbremtechnic, good luck getting hold of him. A lot of his stuff is done/sold through AKS tuning, again good luck getting hold of them too. If you can get hold of a kit from them wouldn't bother looking any further.

 

Lot of info on these on the Mk5GTI forum

 DaveB's kit is the best of what I've seen. Avoid the Creation Motorsport ones due to fitment issues and quality.

From memory, Apikol, Pure Motorosports, Creation Motorsports all make steel carrier/adaptors for the 986 calipers on 312 mm OEM discs and there are many more who use billet aluminium which some see as less robust although lighter of course.

For the 996 caliper then the choice is complicated by the different discs that can be used regarding weight of course but more importantly diameter and offset and so requiring different carriers to suit:

Make Model Diameter Thickness Height Bolts Centre ID Swept area Weight

Alfa Romeo Brera 330 28 39.7 5 x 110 70 65 9.29

Audi A8 314 30 59.5 5 x 112 68   10

Audi A4 Allroad 320 30 52.4 5 x 112 68   10

Audi B5 S4 320 30 46.5 5 x 112 68   10.18

Audi A8 323 30 59.5 5 x 112 68 54 12.1

Mercedes CLS350 330 28 46.5 5 x 112 67   9.92

Porsche Boxster S 318 28 67 5 x 130 98 60 8.6

Skoda Octavia VRS 312 25 49.7 5 x 112 65  8.6

 

The Porsche and vRS disks are there for comparison only as neither can be used. I need to add the wheel lug diameters to the PCD column.

Sorry I couldn't tabulate these in the editor

Yes completely agree but you have to be able to get hold of them! not as easy as it sounds

Don't know if this was aimed at me, lots of usefull stuff but the dimension I need is not there. I am concerned that the Porsche 986 calipers used in the NQSB kit may foul the back of my alloys. I don't want to use spacers or change alloys.

 

I need someone with this setup to tell me how far the outer edge of the caliper sits out from the face of the standard 312mm disk

 

Still dont know if a carrier is out there for the later MQB platform Octy3/Mk7 Golf etc (I know this is the wrong forum but no-one seems interested on those at the moment. guess no-one is messing with new machinery yet

Just nipped out and measured mine through the wheel for you.

Bare in mind this is approx with a tape measure through the wheel:

From disc to outer edge of caliper you will need approx 60mm clearance, I have just fitted this kit 4 days ago so brand new discs to outer edge of the caliper is around 55-60mm. I have genuine bbs ch's with a 35mm offset and have approx 20mm clearance from the caliper face, approx 80mm from the face of the disc to the inner edge of my wheel.

Hope it helps

OctyCal many thanks that is a big help!

Hi guys

I've now had the porsche setup for a few months, and now I get a massive bang at the front of the car when I brake and accelerate

I swear the pads are loose

I don't have the anti rattle shims as there is simply no room?

So to confirm:

- Vw 312x25mm disc

- 986.351.421/2 calipers

- Textar pads from pro-calipers which are the bigger pad to sweep the whole disc, so the pad backing plate has been machined to suit

- no anti rattle pads

Pro-calipers tell me the 2.5/2.7 boxster didn't come with anti rattle pads??? These ones I bought from a breakers did!!

What I don't understand is, why is there no ro for the anti rattle pads please,?

And yes the pistons are fully pushed back

Who is running these calipers with a 25mm disc and anti rattle shims, and what pads are you using please?

Maybe I just need to get the pads skimmed?

Thanks

Just to confirm, I can rock the outer pads in the calipers with my fingers :(

The spring clip doesn't do much

I can post a video?

This listing is for the exact same kit you see on this guide

Ive got a listing up on eBay for a MK4 Brembo Calliper Kit for £670, Im open for any offers so please feel free. The listings currently on eBay and this is the full kit and has everything you'll need for the conversion of MK4 GTI 1.8t 288mm Hub.

The kit includes the following:

1) Porsche Front Calliper x2 Part Number 986.351.421 & 986.351.422 (Refurbished New Seals, Powdercoated in Bronze Gold)

2) Brake pad retaining Pin and clip (Brand New)

3) Pair of Brake Pads (Brand New)

4) HEL Custom Front Brake Lines x2 (Brand New)

5) Brake Pad Dampers x4 (Brand New)

6) 312mm Brake Discs x2 (Brand New)

7) Creations Motorsport Calliper Adaptors x2 (288mm Hub to 312mm Porsche Callipers) (Brand New)

Basically its the full kit, I bought it for my MK4 but it got totalled before I could do this, I knew its was a matter of time them stock brakes would fail me with a GT28. Hence the reason I bought these. Hopefully someone with a MK4 in one piece could put this brilliant kit to use.

GUYS ITS NOW LISTED ON BID, SO PLACE YOUR BIDS BEFORE ITS GONE!

Hi guys , bit of a newby here but it seems like a cool site with a lot of usefull info etc.

I was hoping that maybe someone could be kindenough to help me out with my dilemma.

I have been looking through the web for some time now for more specific fitment details for these brembo's 986.351.422

I want to use a set with 320mm x 30mm 5/112 disks which are on my A4 B7 , I cannot find a great deal of info regarding them being used on an A4 with 320mm disks and I don't really want to go for any bigger calipers really as the ones I have now are basically S4 items.

having had numerous porsches in the past I know how good the calipers are so it made sense to try a retro fit to my A4.

 

anyway, if any help is out there i'd really appreciate it.

many thanks in advance

rob

Mad install, very nice, but I have a question...

 

What was it about the standard braking that you found lacking?  I've had my vRS for a year or so now and the brakes are probably the only part I've not considered tinkering with

 

Not criticising at all, like I say it looks very tidy, just wondering...

Resurrecting a post of old but for anyone who is thinking of doing this conversion you can also use the same method and parts in the write up but instead of using Boxster front calipers: 986.351.421 and 986.351.422 you can use 911 / 996 s rear calipers: 996.351.421 and 996.351.422. The only thing to note is the 986.351.421 uses larger pistons in the caliper but to be honest, I've tested both and cannot tell the difference.

 

The huge advantage of using the 996 calipers is the fact that you don't need to swap the bleed nipples and link pipes, as the 996 rear calipers are already mounted on the front side of the axle, as per Octavia fronts. You also DO NOT have to file away the locating pins to adapt the 25mm disc as the 996 already uses a 26 / 27mm disc.

 

The 996 rear caliper is exactly the same size as the 986 front but with all the work already done for you and because all VAG tuning threads mention using the 986 fronts you can pick up the 996 rears for a lot less money. I got a pair off a 2004 996 C4S for £175, the brake pads in them were almost new (only 0.5mm worn), they had the anti squeal shims fitted too. £35 for powder coating, £3 for Porsche / Brembo stickers, £4 for a tin of good quality clear coat. Apart from that everything else is exactly the same as the original write up. You will need the adapters for the 986 to 112 VAG converstion and VAG to Brembo hoses.

 

All in the conversion has cost me just under £400 including new pagid 312mm discs. 

 

hello, will this calipers fit a fabia mk2 with the 312 calipers carrier (octy vrs mk1, audi S3)? or will i need a diferente carrier for the calipers?

Old thread revival. Does anyone know if this setup will fit under 17" Zeniths on a MK2 Octavia?
