Rs29 rs19, 14, 42, 44, all the rsl, heck any race pagid, ds1.11, cl5, cl6, 1166, Most of the pf range- perhaps not the z, endless, proj mu, carbotech.
Pretty much anything but the 25OOs
I tell you what, even the Z-rated are surprisingly good on track despite their low cost. They're actually quite a good solution for occasional track days providing you manage temp and are not too greedy. I do 7/8 laps on them in the Megane, even at Bedford. Beyond that they would eat themselves quickly but up to that, they're brilliant and can safely/quietly be used on the road, which is handy. I think fluid is crucial too and RBF600 is usually sufficient.Pretty much anything but the 25OOs

Hi Peter, glad to hear the pads helped. I'm ordering a set at the moment. What part numbers did you get? FCP4611H fronts and FCP4663H for the rear? I've ordered some braided lines as I figure might as well do it all at once with the fluid.
yes those were the partsbraided lines makes sense..
had fluid put in for silverstone mid sept and the brakes were great!- no issues running round 6-7 laps of the full circuit- at a time.
DS2500s seem a good compromise for road and track- they were squeaking a little in the first week of fitting , but seem to have settled down now-

I've had my discs warp twice on me now. First time BMW did them on warranty, this time they went from a spirited road drive n the vibrations started coming back. The stock brakes are absolute utter rubbish. To the point were, unless they've put a proper set of competition brakes on the M2 CS, it's not worth the money because the first thing you'll need to do is find some mular to throw a proper set of brakes (discs, pads, calipers, fluids) all round. Funnily enough, the car does actually stop OK and fade wasn't too bad. Just the discs seem to get ripped to shreds! Biggest flaw of an otherwise awesome car... besides it's overall weight of course!
thats weird..
i've done 2 track days.. and no issues on the normal discs,
have replaced pads and fluid with better pads/ racing fluid and its easily good enough. and I was really going for it at Silverstone and Bedford.
sorry to ask a stupid question , but you aren't going out for a spirited drive then returning home and putting the hand brake on are you???

Are the discs actually warped or is it pad deposits on the disc?
I've done two trackdays and whilst I agree the standard pads are sh*te they left no deposits and didn't warp the discs. It felt like a more suitable pad would resolve the brake issues on track....
Worth noting the car was on Cup2 tyres with 27 degree ambient.

Following this.
I get my M2 next week and may do the odd track day.
I use 2500s in my 182 for the same reason as the guy above, I didn't want a squealing pad, nor something that needs temp in to work (wife used to drive it now and then) With the M2 it would be much the same, it's my daily first and track car second. I want something that works from cold and doesn't squeal, but something that offers more bite than stock pads.

As an update, have since done another track day. 2500s, crf fluid and braided lines. Could chomp out 4/5 laps rather than 1. Significant improvement. Also as we said, no squealing.
?I took the M3 on track, standard setup. I tend to be one of the last of the late brakers.
The pedal would go long and last 4 or 5 laps before giving it a break. Ultimately it was the tyres (MPSS) that were overheating and giving up before the brakes.
With uprated fluid and pads, you ought to be able to run without worrying about the brakes very much at all.
DS2500 pads are good, but work best on lighter cars.
To run lap after lap without issue a pad like the Pagid RS19/29 is needed, along with good fluid (I use Castrol SRF). Unfortunately, the squealing is part of the deal. Although my RS19 mostly don't, and when they do a few hard stops quietens them. They also work perfectly from cold; if they don't they haven't been bedded in properly.
A note on over heating tyres - on track days I take out 20% all round (that's 1.75 bar or 25.5 psi) on my 1M. Otherwise, heat and tyre wear are greatly accelerated.

i have yellow stuff pads on my M4. first trip to bedford on OEM pads i lost all braking (fade and long pedal) after 2 laps of the GT Circuit.
after changing to yellow stuff and motul RBF 600 the next track day at bedford i was doing 8-10 laps at a time with no brake issues at all.
no squeal for road use either and at £250 for a full set im very happy with them.
I appreciate most will say yellow stuff are crap but in my experience they are perfect and far cheaper than some of the other options. Im on my second set, first set lasted around 5000 miles including 2 trackdays (Bedford and Cadwell park)
im not sure if they are available for the M2 but worth a look

The stock pads on the M2 are decidedly “bitey” on initial application...I get my M2 next week and may do the odd track day.

It’s worth noting that MDM driving mode uses the brakes to maintain stability of the car, especially using the rear brakes. The stability is not off in this mode, it just allows greater hooliganism so it works doubley hard correcting and controlling wide slides. This could be what is hammering & warping the discs.
I have done numerous track days in mine without warping.

Yep, leaving the traction/stability control on is the worst thing to to on track days (I forgot to mention that). MDM is not so bad, but fully off is the best way to go. I have done numerous track days in mine without warping.
