E46 Brake upgrade

[youdsy]

hi all

looking to upgrade my front disks and calipers on my E46 M3 in the new Year. Been looking at the Ap Racing kit and was wondering what to go for? Firstly is there a need for 6-pot calipers as opposed to 4 pots? are they ovekill? The car is mainly used for road use and havent tracked it as of yet but may do in the future. The standard brakes arent the best as im sure you are all aware of. Will i be better off buying 4 pot calipers and disks or shall i go all out and buy the 6 pots?


Also they are lots of different kits offered by AP racing, anyone point me in the right direction as to which kit would be the best for the M3.

any comments/advice would be appreciated

thanks in advance

ok thanks for that, 6 pots it is then. I knew that AP did the 4 pots for the rear, just assumed that they did a 4 pot caliper for the fronts.

I have the 19"CSL alloys so clearance shouldnt be an issue. Looking at the kits, there are a few to choose from in terms of size and style of disk. Any recommendations as to which one i should go for?

thanks

thats what i was thinking in terms of the AP Kit being overkill, just thought id pose the question. They do look the bees knees when installed yet its alot of money just to make the brakes look nice.

if the difference isnt worth the upgrade price then ill stick with the standard set up. Although arent the standard calipers dual piston only? what pads, hoses and fluid do you recommend that i upgrade to?

brembo or AP Racing? which one would you suggest is the better of the 2?

As Paul says above AP racing Cp5575 front kit is a tried and tested upgrade suitabkle for trackdays at any circuit with the right pads and fluid.

Any other callipers wont give you any btter performance as the APs already are at the limit if the tyre grip.

My APs have done 60k miles inc 50 trackdays and this year i changed the piston seals purely as preventative maintenace.

DONT use the supplied pads on track but buy Pagid RS29 or PF01 at the front of pad deposit with the high temps can make your discs feel like they have been warped.

how do the Pagid RS29 pads cope with street driving? are they ok for driving at such low speeds without getting any real heat into like you do when u use them on the track? Read a few reviews and for racing them seem very good but for everyday use on the road im not so sure, do they squeak at all on the road?
