Franzino said:At first; I did not have a definitive answer if my 19 CSL wheels would fit without spacers with the front AP brake kit CP5575-1010B (Z4M kit with the smaller caliper). I presume you ordered the same kit. I have received a template for the AP brake system that can be used to verify fitment.playalistic said:
The result;
If I look at the template there is space of only 2mm between the front brake caliper and the CSL wheels. I can just fit the metal lid from a can of soda between the caliper and the wheels. I have talked to some people and they say that the fitment with the CSL wheels is indeed okay without spacers. The space in real life between the CSL wheel and AP caliper should be +/- 3mm. Still interested to hear about your own experience.
The AP dealer i talked to said this about fitting the AP brakes at the front only

this is by an AP racing employee that sells the kits to america
note what he says about the clearance..... a Minimum of 3mm..... ;-) i know this was bothering you so se it from the horses mouth remember the csl front is a HIGHER offset than stock wheels, the CSL is retracted MORE than the stock front wheel with +44 as opposed to stock +42................... therefore i dont think this clearance issue would be present with the stock 18" alloy, you'd infact have 5mm clearance.
i would love to stick an 18" on my car to show you but i can't get the clearance with the larger kit :-(
Strange that this set-up does not have enough clearance and maybe need spacers in combination with the oem CSL wheels. When this kit is fitted on a genuine M3 CSL (with CSL wheels), they don't need spacers (Simpsons Motorsport says this). The guy at Thorney Motorsport also told me there is no need for spacers on a Z4M with oem CSL wheels. They also fitted in on a Z4M without spacers (http://www.thorneymotorsport.co.uk/products/images/webDSC01135.jpg). That's something I need to know for sure (before ordering) Maybe the AP template is a little pessimistic and in real life there is 3mm clearance between the CSL wheel and the caliper. I'm curious when the kit is fitted on the playalistic's Z4M.Beedub said:franzine i just wanted to Re-iterate a point, checkout post #29 on page 2

I was not talking about the oem 18" Z4M wheels.... The AP kit fit perfect without spacers behind the oem 18" Z4M and M3 wheel. The wheel I'm talking about is the oem BMW M164 winterwheel set-up for the M3 and Z4M .Beedub said:
I was worried about clearance with the 18" height of these M164 wheels... and my worry was correct...
The AP template hit the border of the wheel and stayed stuck behind the weight. 
Well mine have been on order for almost two weeks now so with any luck I'll have them fitted in a month or thereabouts. 
Cool, I've been assured by Simpsons that they've fitted the slim caliper kit behind OE 18"s many times but a field report is worth hearing!kennef said:very very interesting thread. I'm having my Z4M (wif OEM rims) fitted with the APs from E46 M3 tomorrow afternoon. will update this thread again.
Im pleased to say i had a very long and fast drive monday to simpson, 100 miles of fast road driving, lovely lovely pedal feel, insane speed retardation, they are one of my fave mods, they look great , but arnt the best from cold, once alittle temp is in them they are fabulous, after a day of driving the ceramic optioned porsches these feel just as good, mind bending performance from the aps!!!! So happy with mine, when i came to a halt a simpson they were lightly smoking
Playa youll love the pedal feel and also youll notice the heavy dive under breaking is all but gone as good amount of braking is now been done at the rear.
I got 800 bills for my stock items !!! The stock units go for good cash!!

The AP racing kit for the Z4M will fit 100% behind the following oem wheels: 18" Z4M, 18" M3 e46, 19" e46 M3.... The fitment with the oem 19" CSL wheels is very tight... Some people say they fit without spacers, other say you need them. The real answer will probably be delivered by playalisticga41 said:kennef said:very very interesting thread.

Please do, very curious to see if APs fit behind our stock wheels!
So I sent my car in this morning at 10am to my friend's garage but thankfully, I didn't wait and went to work cos the seller only decided to show up at 4pm. Workers waited for his brakes to cool down but still couldn't get it done in time. Then I went back there at 7pm and they were still busy putting it in. Will be collecting the car tomorrow before lunch so more pictures later.
They do fit behind the stock OEM rims. Fits perfectly as my friend would say. But there's very little clearance between the caliper & the spoke & the rim which is kinda worrying. Will be testing it tomorrow. Fingers crossed.
I can answer you tomorrow as well. I happen to have 1 CSL front rim (8.5J ET:44, don't ask, the other 3 are on the way ) which I plan to test fitment tomorrow.
Can someone please point me to a webshop where I can buy brake pads for these calipers? Seller left me with almost finished pads on the front calipers.
:thumbsdown:
The AP Racing website says there are two different type of pads for this E46 M3 caliper. How can I tell which is which? (the seller is of no help whatsoever)

I read somewhere that the pads for the kit for the Z4M/M3/M3 CSL stock wheels are 1mm thinner than the regular AP Racing pads because of the smaller calliper. Here's the link http://www.cslregister.com/forum/showthread.php?t=4459

Which AP racing BBK have you bought (CP5555 or CP5575)?? The first available 6pot AP kit for the M3 E46 is the CP5555, these will not fit without spacers on the M3 CSL and a Z4M fitted with oem CSL wheels. After some time AP racing made a new kit with a smaller caliper that would fit the M3 CSL.kennef said:I can answer you tomorrow as well.

Picked up the car this morning and the brakes are quite fantastic. Pedal feel is so much better and more predictable. Clearance is paper thin but not an issue. Also needed to relocate the balancing weights to the inner side of the rim.
My calipers are the CP5575 type. You can find this number near the inner-side pistons by removing the caliper from it's mounting. They do clear the CSL rims more convincingly than the standard OEM 18s.

I'm sticking with factory rear discs too on simpsons advice.
