Generally, the bigger the brakes, the better the fade resistance. More metal means the brakes can absorb more heat before the pads get too hot and go
'off' or fade. Larger brakes (such this upgrade I have designed for my Beetle) are ventilated so have more than double the surface area for quicker
heat dissipation.
Slotting (not essential, but I have chosen slots for my prototypes) helps deglaze pads (at the expense of some operational life) and helps allow gas
emitted by hot pads to escape from between the pad and the rotor surface, helping redue the 'butter in a frypan' effect of a hot pad uselessly
sliding over the rotor's surface on a layer of boiling gas.
On top of all that, a larger pad provides more initial 'bite', takes longer to get hot AND is able to dissipate heat quicker.
Mount these bigger pads in a finned alloy calliper like the PBR single-piston slider I have chosen (unlike the Beetle's steel ATE units) over vented
discs and put them under a car of half the mass capability of the brakes and I would say it wil be very, very, very difficult to make these brakes
'go away'...
Gayanne, despite your concerns I don't see why these vented road-based brakes wouldn't be sensational for 'road registered'-class competition
Beetles (ie not sports sedans with fabricated suspension).
Many aftermarket racing callipers (such as WILWOOD and AP that you have chosen) are delivered from their manufacturers with the prominent warnings
"NOT FOR HIGHWAY USE DESIGNED FOR RACING USE ONLY", as they are not 'validated' for legal road use eg: they don't have piston dust seals etc etc.
From my experience with aftermarket brakes on drag and circuit Commodores etc etc it is also generally recommended they be diassembled and inspected
after every race meeting. That is not something that I, or many other people, wish to do for a fast road car!!

Yes, I was curious, too, so I chucked 'em on Mum's dodgy old bathroom scales before I fitted them. The extra mass of the vented rotor, larger pads
and bigger calliper is roughly 3kg per side: 12 vs 15kg balljoint-to-balljoint

Yes but if they can pass the German TUV, they will piss it in over any ADR.
Also I used the wide 5 as most on here have early vehicles but the CSP brakes are alos available in the later 4 bolt pattern.
For about the same price of $1200.
Come on how much are you going to sell yours for???
I only ask as before you edited I am sure a figure of $1500 was posted????
Cheers

Dave, I think you better do some more HOMEWORK.
This would be my suggestion for your study itinerary.
#1 Currency Conversion e.g. $1227 Euro to AUS$ or an easier one $696 Euro to Aussie$
#2 Product comparison exercise. (i) looking at pad size (ii) Replacement disc cost (iii) Parts availability (iv)Alloy caliper option.
#3 Customising options available on product order. e.g. Stud pattern options, slotted/cross drilled variants, pad material selection......
#4 Customs Duties,GST and Deliver costs of goods of more than $1000Aus entering into the country, and approx 30kg in weight.
Then maybe share your answers?
Cheers

There is lots and lots of very valuable info in this post, but I suggest maybe take a look at what you are typing before hitting the post reply button
- and ask is this still on topic? Is it useful for this discussion?
I am not trigger happy with the edit or delete button so wanted to give a little heads up first. :vader
That aside, I'll always commend someone for doing something different and sharing the idea/info for "useful" debate. It would be a shame to turn
this into a shit fight.

Gee, it's been a busy day!
Yes, this thread is still 'on-topic'... kinda! I'm not the first person in the world to install vented discs to the front of a Beetle and some
people are questioning why I am 'reinventing the wheel' by doing it. Yes, there are other commercially available disc kits but like a lot of
products, oils ain't oils!
I reckon my upgraded brakes are bigger (thicker discs and larger calliper and pads) and better (wheel choice, captive studs, PCD choice, spare parts,
performance!) than the kits that are available, one of which appears to retain the same size brake pad as standard. That's why I put the effort into
coming up with better brakes with a larger pad area and with V8-specification vented discs.
Questions, discussion and opinion about all this stuff is always good... as long as it is sensible and/or can be backed up with facts!
I'm off interstate for a week so won't be doing any more hard driving until I get back. I'll let you all know how it goes.... err, stops.  Then I'll install the rear discs for even more fun! :thumb:thumb

With what I'm currently working on, brakes are starting to become an issue, so I'm also interested in the end result. I've looked at quite a few
different brake packages for VWs, and have come out of it with my head swimming with the complexities involved in selecting the right setup. Something
about reading up on the variables involved with stopping lends respect to the investigation and construction of something like this.
Now. Time to start selling my body to science.

Yes, as with any 'go where no man has gone before' project, there are
lots of variables... tyre pressures can influence how brakes work along with calliper piston size (I have attempted to match/balance performance front
and rear as far as possible within OE specs for callipers), master cylinder (I found it necessary to fit a larger one to 'feed' the extra calliper
capacity), brake pedal leverage ratio (I'm not playing with that!), friction material (I will be using the same high performance compound front and
rear), wheel size (same 15x6-inch front and rear Falcon rims for now with sticky Falkens), weight distribution (can't do much about that unlress I
put the engine in the front!:duh) yadda yadda yadda... I am busy dealing with all this stuff to get brakes on my Beetle that work to world-class
standards

Jackjones.
Why are you so upset regarding me posting pictures of my bus?
Are you jealous?
Where is your vehicle and did you do it all yourself?
You must be driving a shitter as we have never seen any pics of it.
If you work hard and save up your pocket money, you to might have a vehicle as good as mine one day when your mum and dad let you go for your driving
lessons.
I presume you are in your early teens as that is how you come across.

back on topic tho'
vwcool, i like the look of what you've done, i really like the idea of using local easy to source parts.
good on ya for having a go!
apart from the petty schoolgirl bickering this thread has been a very enjoyable read!!

Yep thanks Dave
I am not upset nor Jealous of your Bus
I don't want pics of any of my cars on here.
If you must know I don't like splittys but each to his own.
My Kombi is a T3 and will always do most things better than a splitty no matter how much u spend on it , but if looks are everthing to u then
fine.
I have done several resto jobs, wouldn't like to count them.
I also do my own engine work.
Back on topic what size pistons on those calipers ?

So JVL.........
front discs and calipers used on a 1800kg vehicle, matched with rear disc and calipers also from an 1800kg vehicle, would not be a benefit on an
800/900kg car???:duh..........all being factory proven components.
This system WILL BE proven before it will be available for interested parties to purchase.
P.S There's plenty of VW racers (CT, JAK,Rudy,Greg,Ben,Myself, etc etc......) using far smaller brakes now...................As a racer I will be
first in line to fit this package.

Just interested and I know it's a bit below this package but I haven't heard anyone mention the Shermann conversions you can get. Are these similar
setups with using local stuff and is the Shermann conversion 4 wheel disk setup adequate? Does anyone run these? The fact is we are all running light
weight cars that really dont need huge stopping power unless we would be doing track work. When was the last time you experienced brake fade?
Seriously.

Craig not once have ive said these brakes are no good, at this time being ther not a proven brake system until they are tested and have a star
approval.And yes these brakes would be a benefit to a car under 1300kgs and yes if the affordability is there for budget racing you would buy vwcools
brake system but if i had a choice ill still buy a proven brake system which has been around for years that are lighter,raceproven and approved buy
many racers. p.s Craig ive built proven racecars and raced as well and crewed learning race craft over many years and what i have learned you dont
take short cuts to risk anything.JVLRacing

Show me a proven race system that I can buy "off the shelf" for my street registered VW..................where it needs no modification from "me"
(the end user) and is realistically priced, with the same potential stopping power.....................is there one?
What would you recommend JVL as an alternative (equal braking ability) to the system VWCOOL has developed?
And what would this system consist of........and all importantly what will it cost?
