What options are there for larger rear discs. I've seen the Trox? but that came in at £400 but did look the dogs!
What was included in the Porsche kit and costs?
Have I missed any?

I think Barbs @ torqueitalia does a bigger rear disc conversion, using a bracket on the existing caliper

Someone mentioned that you can use Seat Cupra R rear calipers along with 16VT front discs. Of course you would need brackets for the calipers, but they're wide enough to accomodate ventilated discs.

Under heavy braking, there is so little weight over the rear wheels that I wouldn't be sure that you gain any benefit.

Have you seen a problem with the rear brakes? Perhaps it's a purely a cosmetic exercise?

i use a rear big brake kit,using same calliper,brackets and 285mm discs.
cost to greece for new brembo drilled discs+brackets+screws and all of needed stuff,190 gbp.
fits easily by ourselves,not a noticable difference to braking,but still eyecathcing,compared to the "baby"251mm oe fiat discs.

Where did you get the kit fo 190 gbp?

Andre

from greece.

Do you have an adress or webstie?

Andre

no...are you interested in one kit?

You have PM

does uprating the rear brakes upset the brake bias ?

I have a spare used set of front 20VT Brembo discs
which are the stock 305 mm items. Can I have them
lathe down to , say 280 mm , and fit them at the
rears with a suitable bracket for the stock rear
calipers ?

Thanks.

the tarox kit does give a noticeable difference to rear brake performance.

available from www.gazzella.cc in the UK or via barbs at TI.

basically , if I read it correctly , with the Tar-ox
rear brake kit , you get the disc and a bracket.

they don't even give you an upgraded caliper , you use
your stock caliper.

if that is the case , wouldn't it be easier and far far
cheaper to fashion your own bracket and get some larger
discs to fit ?

You dont need to uprate the caliper, that will upset the bias much more, the extra diameter of the disc gives an increase enough in braking effort.
The trouble with a solid disc at 300mm is warping, the tarox kit uses an alloy bell to mount the disc, this prevents warping.
The bracket is a big chunk of alloy machined to the correct size to mount the caliper, it could be done but you'd have to either own a good workshop or have a workshop make it up for you, then you'd have to find a 300mm disc and have an alloy bell made to mount it.

hi Jimbo,

thanks alot for your input here.

why do you say that there is an issue of warping for
300 mm solid discs , thus requiring the separate bell
setup ?

I thought that the bell-setup is meant to reduce
unsprung weight (ie , the bell is alloy).

Thanks.

I dont know the exact science behind it pistole but if you have a disc made out of a single piece of metal 300mm diameter, its only the outside 5cm of the disc that will heat up and cool down all the time as the brakes work but its still part of the one piece of metal that isnt heating or expanding in the centre of the disc, now because the disc is only relatively thin at 12mm the chances are the metal will warp out of shape.

The alloy belled discs are a 2 piece unit so the outer friction surface disc can move indipendantly from the fixed centre bell as it expands with heat so its less prone to warping.
Being light is also a bonus

take a look here...

big rear

I must admit that the conversion would be mainly to do with styling rather than performance but obviously the performance gains would be appreciated.

Basically I'm trying to see if it's worth me buying the 3G rear breaks from the Group Buy (as well as the fronts). I looked at the std rear discs and they're just not noticeable (I've been unsuccessful getting a picture of the 3G rear discs fitted) and I'm thinking would I be better off saving the money form the rear disc group buy and putting it towards a conversion at a later time . But after seeing the pictures on the Tar-ox rear discs they're not going to match the 3G front discs . Before you all say I'm being pedantic IMO little details like that make all the difference when it comes to styling.

The Pagid front discs (better than 3G but more expensive ) have the same style grooves in the disc as the Tarox if your just after cosmetics.

jimbo probably just coincedence, but statistically the pagids have warped more than the 3G's.

i think nigel is the first to warp 3G discs? or atleast i havent heard of any others.

Thanks for the help. I think I'll just commit myself to the 3G's for now and maybe have another look at larger rears next year .

I fitted a set of EBC turbogrooved discs to the rear along with uprated pads.

Look stunning.

As Rog said, I wouldn't bother too much with rear as does FFUK all and can even cause you to loose control...

Much better to spend £££ on the front!

Fergie have you got a picture or site I can see them on?
