I'm looking to change my brake pads and possibly discs before I go on the track day at Donnington in November. I have heard really good things about EBC Redstuff pads. But I have also heard that with the EBC dimpled and grooved discs there is excessive noise even when not braking is this true?

Does anybody have any other recommendations as to pads and discs or should I consider staying with OEM as they do seem pretty good.

The car is driven reasonably hard and I do get frustrated with the amount of brake dust generally found on my front wheels 5 mins after I've cleaned them.

Ideas and suggestions would be appreciated.

Cheers Andy

 

Track days are harder on brakes than fast road driving, so uprated pads are certainly a good idea. Make sure you uprate all round though. Even though the fronts do most of the work, when they start to fade on teh track the rears pick up some of the load and overheat and crumble very quickly.

I use porterfield R4S pads and find them very good for both road and track driving and don't suffer from the fade you get on track with oem pads. I personaly wouldn't bother with grooved and drilled discs unless you go for top spec discs, eg spoon. Most of the others are just remachined 'oem spec' discs.

 

Using Ferodo DS2500 all round and Spoon discs up front, lots of feel and stopping power and very little fade at all. Absolute bastid for brake dust though. Just trying a set of J's grooved discs with the Ferodo's at the moment and they are slightly quieter than the Spoon drilled discs.

 

The spoon disks can crack around the drilled bits. someone got the OEM disks analysed and apparently they're very good from a metallurgical perspectice (Biker1 I think)

I've run Porterfield R4S like lower, and still run them on the rear. Currently on OEMs on the front due to laziness. (I had a spare set when the R4S ran out)

You don't NEED to upgrade for the track, as long as you keep the sessions short. But it helps.

Or you can go the whole hog and get front brakes that can stop a bus. PJL runs those. The extra pots help dissipate the heat.

Braided hoses and replace the fluid is a good start.

finally, two cheap options are some ducting to get air over the front brakes, and also remove the dust shield from the back of the brakes. It allows greater airflow. But this second one is probably not good for a car that spends most of its time on the road.

 

Where would I get the Porterfield R4S pads from?

Lurking Lawyer was selling a set but I was stupidly greedy and haggled rather than offering the full price and missed out

 

I am using discs from Racing Brake on the NSX, I would recommend them for anyone and a great weight saving over the standard discs.

Here they are in S2000 fitment, not sure on the exact weight saving but by hand the Racing Brake ones seem to weigh the same for a pair as a single OEM one.

But it depends on your track experience.

Generally the more experienced you are the better brakes/pads etc you'll need.

The best thing about the oem pads is their cheapness.

You lot are lucky. The M5 suffers from terrible brake fade and therefore there is little choice but to invest in some better pads to use for track days (and they're not cheap).

 

Ive got Redstuff discs and pads all round. The noise Iim getting when not braking hasnt been solved yet

I think its either a slightly siezed caliper (s) or something up with the pads. Im going to change them v soon and will report back. The brakes themselves are great from a performance point of view, although this is always speculative because you are used to the shit ones that you have just replaced - normally because they were worn!

If you do go for them online, type scooby86 and get 15% off

If I was buying again, I would try the StopTech kit from the states which has hoses and fuid too - or Pagids

The Stoptech kit looks like pretty good value, does anyone have any experience with it??

 

Check with the US guys.
