R36 BBK options

[alien]

Hello all,

I am looking to upgrade the front to a big brake kit setup. Would like to know what are some of the options out there.

Thanks,

I'd seriously advise against upsizing the R36 brakes. They're already huge. If you want better fade resistance, look up the RDA 7382D front rotors. They're same sized but have dimples and slots for efficient cleaning of pads. You can also look at the DBA 4808XS which is cross drilled and slotted as well as painted gold - but it's twice the price.

They might be huge (340mm???) but theyt are still only single pot sliders & they are as heavy as all get out. A multi-piston BBK sticking with a similar diameter rotor will provide more consistant clamp force & save several kg per side.

To the OP: Have a look in the Golf & Octavia areas. Plenty of folks have fitted BBKs and the mount points are common between the Passat & the Golf/Octy. The main difference is that the Passat has an alloy hub carrier & the Golf/Octy has a steel carrier so the Passat has more metal at the brake mount position - this may require some thought before committing to purchase.

Depending on what your engineering skills & how dedicated to DIY you are solutions range from adapting Porsche monoblocks to a bolt-on kit from PB Brakes, VWRacing, HPA, etc.

Step 1 would be to ask for a template so you can check caliper clearance, etc

Brad - are you stating that the multi-piston monobloc calipers are several kgs lighter than stock? Or are you referring to 2-piece rotors as well?

The calipers are lighter. They are made from aluminium instead of cast iron.

here are some assembly weights that I'd noted elsewhere. The R36 has the 345mm rotors i believe.

Brakes (caliper + rotor + pads + bolts + adapter)
OEM:
stock 312mm - 14.5kg
TTS 340mm - 20kg
S3/R32 345mm - 21.5kg
TTRS 370mm - 17kg
RS4/RS6 365mm - 17kg
RS6 V10 390mm - 21.5kg

Non OEM:
VW-R 352x32mm - 12kg
K-Sport 356x32mm - 12.25kg
Brembo 355x32mm - 13kg

Caliper + bracket weights:
312mm GTI - 5.5kg.
Golf R / S3 - 8.4kg
A Forge motorsport 6 piston - 4.5kg
A Stoptech 4 piston - 5.2kg

I have no idea what an R36 caliper weighs.

There's also a lot of weight to be saved going to a 2 piece rotor.

When selecting a BBK you need to consider the piston area. R36 is a 54mm diameter (?). Area is 2290 mm sq.

Hi

I fitted the VWR BBK to my R36 along with their new 2-piece rear rotors. As this kit is VW OEM it bolts straight on, and it'll work with the OEM 18" R36 10-spoke wheels too - having said that I did fit HRE R40 wheels for even less un-sprung weight...

Lemme just say that the stopping power now is simply amazing! The very noticeable less weight is also a bonus.

I decided to go all out and do the rear rotors as well, but with the OEM caliper. So I now have 2-piece calipers on every corner and 6-pot calipers on the front and the OEM calipers on the rear!

Despite what other advice you'll get on this topic, I'll bet none of them have actually experienced the VWR BBK in person...

I got mine through European AutoTech In Monavale, Sydney. Not a cheap exercise, but worth every penny IMO.

Thanks Andrew for your input. Is your car a daily driver? I can't fathom a braking benefit in daily driving. Even with aggressive short stints, I've never experienced brake fade.

I do want the reduced weight for ride comfort, handling, acceleration & fuel economy.

Also, what sort of $$$ ?

Hi mate

Yes my car is a daily driver as would most of the members on this forum be. To be honest, I'm not a racing driver and I didn't install the BBK because of brake fade - I think I'd lose my license before that happened! Its more about just having better brakes, and they look very cool too! None of us here upgrade/mod our cars because the OEM bits are failing or don't work well, we mostly upgrade parts because they either look good, or work better! Trying to apply any logic to modifying cars is just, well, you know...!

The end result for me after all the mods I've done is a car that handles way better, stops way better and introduces more driving confidence too I guess - and it sure does look better too!

No-one really needs coilovers, BBK's, low profile tires or lightweight wheels - but they sure make a difference in how the car feels and drives.

As for the costs, well, when I did the BBK the AU$ was quite high, on parity at least, so all up, fitted including the rear 2-piece rotors it was about AU$5.5k.

The parts can be got online for much cheaper than that, and if you're handy with the tools you could probably do it all yourself, but I'm not and I couldn't be bothered anyway even if I could. Try Derek at European AutoTech in Mona Vale Sydney.

Good luck!!

For looks you can also just do the brake retainer springs from newer R models, under $150. Fronts only though.

I looked at this but as is said earlier in the thread, whether or not they are single piston, they are extremely good brakes for a daily, even in the hills I encounter minimal fade and the overall dimensions of everything is more than adequate. They also feel amazing through the pedal, very sensitive to the point where I let a girl I was seeing drive and she was expecting the same brake response as her Barina, almost put us through the windshield! Have had a workshop comment on this too.

It's a lot of money for a cosmetic/track benefit only.

The feel and stopping power of the BBK is just sensational, as is the weight reduction in each corner, the car just drives way better. Its considerably more than a cosmetic difference as in the "R" retainer springs for instance - that actually do nothing at all except make you look a little, well... you know...

But, if you can't afford it, then, don't do it - easy!
