Hi All,

Ive been offered some rear EBC grooved disks at a very good price, so I'm after the fronts to match,

Is there anywhere that sell them at a good price or are they pretty much same price anywhere you go?

I note Euro Car Parts discounts don't work on this brand.

Try companies like Demon Tweaks perhaps. I usually just google the part and see what companies come up.

grooved is for show and nowt else..can you not get some qua;ity normal discs,,i had ebc dimpled/grooved discs on my st with red stuff pads,,absolutely no difference between them and ford discs and motorcraft pads..well except the price..i run pagid all round on my e46,,although im thinking of getting better pads..on my e90 i do not know what it has on as ive only had it 1 month and the braking has been fine..pagid are very good quality discs and they do not rust ..faces do but not the shell.

Grooves allow hot gases to escape the surfaces between the pad and the disc for better cooling. In theory offers a bit more bite as well.

i will put you in contact with a and k motorsport if you like,,maybe on a race car yes.on road car,not a chance..the grooved bits have even been known to make the disc weeker.if you want stopping power.get some decent pads,,all the grooved will do is eat pads quicker and spew more dust out.

Why not just get them from EBC online? They're normally the cheapest tbh

Just To add Grooved , drilled discs do help as discs heat up a lot as above it assists cooling and gasses to escape and does decrease the chances of warping them.

i had ebc grooved and dimled on my st.along with red stuff ceramic pads..were on the carwhen i bought it,braking was good,but so was the ones i replaced them with,,and quite a bit cheaper..not saying they are no good..just no better.

[Mus22]

ye no I'm not saying go performance however iv noticed lately on the quality of standard discs they are getting worse and worse.

[billyboym3]

Tbh, its only because I've been give the rears pretty cheap I'm doing it,

Im hoping they will look pretty decent thats all. there rarely big disks behind the skimpy 313s

True, but the significant majority of heat is caused by the pad compound.

Therefore buying decent pads is always more important than discs. By investing in grooved and drilled discs you are improving the symptom not the cause.

So to reduce the chance of warped discs change the pads. If you want increased brake dust, increase pad wear and increased risk of cracking, to keep your brakes slightly cooler in race conditions then go for drilled and grooved. But if you're at this level you'll be chopping into your bodywork to increase aerodynamic brake ventilation, but you don't see people do that.

On the road you'll never get to the temps where grooved or drilled will be beneficial. They look good because they are synonymous with race cars, and that's it.


To the OP, check out MTEC's site if you want cheap grooved discs.

I have the slotted and drilled as well.
TBH as I don't track the car I'll probably juts get regular discs next time.

Although I could really do with a big brake kit to stop this monster.

does not matter what bhp or power a car has,,your still braking from a speed which most cars will get to..ie if your doing 100 mph and you brake..its the same in a 335i with 300 bhp and the same in a 450 bhp car,im not saying a better brake set up is the same at stopping distances ..just the same at the same speed.your car does not know you got better brakes.

Sorry that doesn't make much sense in reality.
I tend to travel at higher speeds than I should, which with more power means I can get to in a shorter distance and time than before. Plus I enjoy late braking. More stopping power will always be welcome.

It's why you don't find tiny brakes on powerful cars.

yeh thats true,but im saying dont matter what car your in..100 mph is 100 mph and it dont matter what bhp your car is.yes better brakes stop you quicker.but your point was that your car was a beast,yes it maybe,but braking from high speeds .which any car can do

[AWSAWS]

Yes I get that. I did physics. Kinetic energy being half mass times velocity squared.
It's just that brakes are a method of turning kinetic energy into thermal energy. Greater power equals a greater transfer of energy in less time. Generally resulting in higher speeds.

Ill give ya some advice when buying EBC brakes.........Don't.

There toss.

OEM discs.

also when buying these after market discs..ebc/mintex and the like,,get them from a proper shop..most e bay ones are just clones anyhow..all made in same factory and put in different branded boxes,then the e bay sellers buy them thinking they are genuine,then sell them to folk who think they are upgrading their braking system,when they are actually down grading it.
