    Hi guys,

    Following on from my earlier post - I will be tracking my car this year and wondered if you guys could help with the following?


    If running dedicated front track pads (for example; RS29’s) could you still run the rear OEM pads and be OK? (bearing in mind rear braking accounts for approx. 25% of your total braking force).


    If not, would running a fast road pad in the rear be OK instead? Such as Ferodo 2500 or EBC yellow?

    When I say "be OK" I'm referring to will the OEM pad hold up and not crumble? I assume it's harder to detect rear brake fade given the direction of travel/front brake bias...

    Keen to know what experience people have with mixed pad set ups please.


    Thank you

    On the older M cars I would say no but the M2 seems to be decidedly light on its brakes. A friend of mine (who is a fellow Cutter) does the Nurburgring with me every year with RS29s up front and standard rear with no issues whatsoever. I mean, better pads in the rear won't hurt but you can get away with it.

    I've used yellows front and back before and thought they were pretty good for money, they can handle the heat of constant braking without fading and bite quite well, very dusty though. You will go through the rear pads quite quick though if you leave traction on and it keeps stepping in.

    Interesting, I've heard the opposite across forums and on YouTube (in that they're really a fast road pad and not fit for track). Obv if they worked for you that's great and thanks for your reply too :)

    Depends if you drive with traction control on imo.

    if you drive with it on the oem pads will get destroyed due constant brake pulsing.

    ^^^ that is true, my other half did a trackday in my car with traction on all day with basically new yellow stuff pads and with traction kicking in all day shed used over 1/2 of the rear pads.

    For a proper tracknut they will be shite, I used the yellowstuff for my 1st 2 trackdays and they stood up to test no problem but I wasnt full pedal to the floor at the optimum braking point every corner as I were a novice.
    After them 2 days, when i started braking alot later and alot harder trying to shave time off my braking points I went rs29 all round and yes they are better, bite better and last longer but they are £500 for all 4 wheels. What I'm saying is for your 1st or 2nd trackday for £100 yellowstuff will be enough

    Ah right, I understand what you're saying. Makes sense, but for the sake of having to buy more pads again a few months down the line Id rather just go straight in with decent stuff and be sorted longer term.

    I've now purchased Ferodo DS1.11's front and 2500's for the rear, c£340.

    I tend to drive with DSC off now (didn't when I first got the car!) as I find its a good way to learn throttle management post corner, and well...we all love oversteer right ;)

    I'd just go RSL29 all round, done Bedford GT in my M2 completely stock and the brakes were shocking! Swapped to 29's plus decent fluid, goodridge lines and a small brake duct (stop the calipers turning green) and the brakes were leaps and bounds different at Silverstone GP.

    But the 29's do rattle and squeak... a lot! As I'm not on track for a few months I've swapped back to stock pads and even from the first press you can tell the difference.

    I run RS29’s in the front and god knows what in the back. The rear discs and pads have been on there for 4years and still have loads of life, I’ve been through probably 4 sets of front pads and one pair of front discs in that time.
