Despite Andre's very nice 3d printed cooling kit I was still able to crack a pair of my Peformance Friction discs for my ever trusty AP 5575 kit I have had for some years now (I had found over the years PF were better than AP for cracking, similar price). Whilst braking performance was (almost) never in doubt, replacing discs at £600 a pair more than once a year was wearing (boom) a little thin... this is a 356x32mm disc so considerably bigger than stock
I'd heard of the new generation AP calipers being used in e46m3s, and what really sold the idea to move from the old 5575 caliper to the the new 9660 was the ability to run ex BTCC discs (& pads which I was already using with the 5575 as they fit kinda). After each race in btccc the teams are obliged to junk their discs and pads used for perhaps all of one round, which means a nice supply of very expensive consumables at at very low price (Try £80 for discs instead of £800!).
368x36mm
Knowing that the Z4M 5575 AP kit is slightly different in the offset of the bell and bracket to the e46m3 kit I was unsure as to whether the 46m3 kit would fit correctly. Consensus from the designer of the brackets & bells was that it would be fine, I wasn't convinced but went ahead anyway. Turns out they fit perfectly and actually required zero shimming as opposed to the 5575 Z4M kit which did require a tiny bit. Happy days.
Caliper design has moved on a bit in 15 years, these things are pretty sexual (to these eyes!).
old 5575s
All fitted
Super happy with it (been running it since late last year), if anything I've always found the z4m specific front & rear kit to be slightly too rear biased, I don't have that feeling now.
Yes it's quite an expensive up front cost (you won't see much change from 2.5k all in) and probably overkill for most of you but if you do track the car a lot my maths says the ex btcc consumables make it a pretty good option.
Hopefully someone finds this useful, if you want to know more about the kit drop me a pm.
car still not gone in for paint so excuse the new primer bumper, not a two tone kind of guy!
As such need to decide to whether to paint the rear caliper lettering white or the fronts yellow to match :scratchhead:
