Hi all.

Did my normal search, yes I know how to use it properly.

Real quick and easy question which only some people will be able to answer.

With cold braking, how bad (or good) are the DS2500s in compairson to the RB74s? I've previously had RB74s and didnt really have a problem with them cold. I just had to remember to stand on the brakes at the end of my street, after that they were fine. From what I have found out, the DS2500s are a better pad for everything else. Just cold braking...

So really all Im asking is. If you have had RB74s and DS2500s in your car, for cold braking which was worse or better.

Thanks.

I've run RB74 and am running DS2500 on street now. And honestly i'm not impressed with the DS2500, they have no 'bite' maybe i've got a bad set. Don't get me wrong they stop me fine, but i have to put a bit of pressure on the pedal, even if warm.... where as when i put DS3000 in for track days, they bite nice and hard... doesn't take much pressure on the pedal.... but maybe i got a bad set?

The RB74 i found the same as you, hit them the first time and they are average, but after that they are ok...

I think i'm going to give endless a go for street pads when the DS2500 are out...

Well I replaced my RB74's with DS2500's. I found the Ferodo pad to be quieter, work & recover better at high temperatures, work better from cold & have good feel.

The key is to bed them in properly. If you don't you will suffer from the maladies listed above.

They are a better pad than the RB74.

oh. i can confirm this lack of bite. i have them on the rear of mine in ap 4 pots. and performance friction carbon metalics in the front.

for the life of me i cant get the rears to lock.

hence my master cyl thread

thays with 50/50 pressures. the pfc in the alcons just work to well. but im gettinfg some diferant rears with bigger pistons so theres more pressure aplied to the pad. curantly ive got 41.3/44.5 front and 27/27 in the rears. changing to 30/34 in the rear.

i want to get it to lock up so i can tune it properly. rite now all it does is cook the fronts cos the rears just arnt being efective at all.

any idaes?

I personally think the DS2500 are a great pad, had no problems at all. But my car barely sees the road more than 5 times a month, so anything brakes better than my work car :nyaanyaa: .

On the track the DS2500 worked VERY well, i was very impressed.

I have the 2500's... yeah not as much 'bite' as normal street pads but they are very linear... push harder and you slow down more;) didn't give me any problems at PI and I used them more than I should of because I was scared! lol

I hate spongy, bitey pads on the street... euros always have that soft peddle feel, I don't like it... and they tend to be much more dusty

Why put in a caliper with larger pots if you are already having issues with a lack of rear bias? It will only make it worse.

Check the pads aren't glazed & try removing some pad material fron the area closest to the hub ie increase the effective working diameter of the pad.

I've also had the ECB red stuff recomended, along with a halk pad, cant remember which one?

So lets throw them in there too. From what I have found they are all about the same level. With maybe the DS2500 being a bit more track friendly than street friendly.

I thought i bedded them in properly, same way i usually bed in pads, go out do some big stops, get them cooking, then let them cool down without braking.... usually works.... Do you think i should try roughing them up and bedding in again? Maybe i'm just used to the bityness of the DS3000s

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
