    Cutters,

    I am considering a brake upgrade for my E46 M3.

    I am content with the OEM brakes' road performance, but fear that they will not be suitable on track. I am not overly concerned about stopping power (although that would be a bonus), my main aim is to reduce brake fade.

    My M3 will remain a full weighted car (it will not become a stripped track car) and I will be doing no more than 5 track days per annum. Besides as it's low spec (no heated seats, no Sat Nav, no HK, no power folding mirrors etc) I should be alright in the weight watchers department anyways.

    As per the thread title, please vote on which Big Brake Kit you think is the best value for money in relation to the above intended use.

    I have listed today's current prices (which cover front and rear) below:
    • Alcon Advantage Extreme 6 Pot 365/32 + 4 Pot 343/28
      • £5,262
    • AP Racing 6 Pot 356/32 + 4 Pot 328/20
      • £3,870
    • Brembo GT 6 Pot 380/32 + 4 Pot 345/28
      • £6,270
    • D2 6 Pot Fixed 356/32 + 4 Fixed Pot 330/32
      • £2,198
    • D2 6 Pot Floating 356/32 + 4 Pot Floating 330/32
      • £2,696
    • K Sport 8 Pot Fixed 356/32 + 4 Pot Fixed 356/32
      • £2,330
    • K Sport 8 Pot Floating 356/32 + 4 Pot Floating 330/32
      • £2,573
    • Stoptech Sport 6 Pot 355/32 + 4 Pot 345/28
      • £5,050
    • Wilwood 6 Pot 355/32 + 4 Pot 327/28
      • £3,392
    • Custom
      • If you select this option then please explain what it is you did and how much it cost.
    Cheers

    If you're willing to go used then you can pick up a set of AP 6 pot front calipers, with discs and pads for about £1500. They're on quite a few cars so they do come up every now and then. You don't see the others come up for sale as often, especially the Alcon and Brembo.

    Hi,

    Have a search around here as there was an independent test of a number of different BBK's and the results were that some of the mid range BBK's outdid the expensive ones.

    Perhaps another member will know the link/thread..

    Cheers, Dennis!

    So many pad and disc options and easy supply of spare parts and rebuild kits.

    I’ve never even seen a rebuild kit for a Ksport or D2

    You don't need a big brake kit on the rear. The fronts do the majority of the hard work.

    Can't speak from personal experience of the others but I found the APs were easy to fit but most importantly consistent braking performance. They are more expensive but if you do sell 2nd hand they hold their value reasonably well. Id pick up a 2nd hand set as they do come up.

    Mine are the AP5575 fronts and 5144 rear. You can pretty much fit most aftermarket wheels with ease worst case a small spacer is required ie 5mm. Spare parts are easy to obtain.

    Ksport are the cheapest but I have read people having issues with fitment as well as having to file down pads, dont get none of that with APs.

    I’d always advise AP Racing.. but the yellowspeed kits (for the money) do a good job too.

    I think that those brakes suspiciously cheap. If they’re legit they look great.

    AP all day long. You don’t need the rears.

    I’ve just gone from the common Porsche Boxster S BBK to the CP9660 kit with 368x36mm BTCC discs and pads and they’re amazing. Perfectly well mannered on the road, and savage on track.

    Surely upgrading the fronts to 6 Pots whilst leaving the rears stock would upset brake bias?

    It’s not essential to be honest. It’s nice if you can. But the best way to do it on a a small budget from my experience is
    Bbk up front with a high end pad
    Standard at the rear with high end pad, lines and brass guides

    If you can afford to run a bbk at the rear do it with a cheap pad. When I ran rs29’s at the rear it was to much when trail braking. Now I run a mintex pad in my rear AP and the balance is a lot better.

    I found the balance under heavy braking was better with the bbk allround. It’s not a night and day difference, but a slight difference all the same.

    It all depends what you are using the car for. For road the standard brakes with a few tweeks are more than up to the job. On track they lack abit.

    But then you also have to look at tyres. This is your contact with the floor. You can have the best brakes in the world, if you have **** tyres it counts for nothing.
