Hi,

Craig- use Super Flex much better
product than the Powerflex stuff.

The guys at Superflex understand
hardness and sprod ratings much
better.

Get the front rear wishbone adjustable
ones with S/S insert, and the rear
ones, plus the RTAB's or if you want
to change rear camber and toe
K-mac do a bolt in eccentric bolt,
or you can use the E39 M5 eccentric
bolts but will have to have the
bolt tabs welded on to the rear
sub frame.

www.superflex.co.uk

The 850 Brembo Calipers come in
2 versions, lug, which I beleive was
also fitted to some e32 740/750 as
an optional upgrade, and the radial mount.

Try and get the Radial ones, and the
you can either have some alloy mounting
brackets made, BG Developments or
Hi Spec will make them, or its quite
easy to buy some 6063 alloy and make
your own.

Some of the lug ones bolt straight on but
not all.

330 brakes are just able to run larger discs
and they will cost almost as much S/H
as the Brembo set up.

On the LSD, the E36 3.0 M3 in the States
ran a 3.91 LSD which will bolt straight
in. It was because it was non S50 engine
and they wanted to keep acceleration
up to around 5.8 for 0-60.

There is also a 27mm e36 m3 front ARB
which with the Superflex ARB bushes would
alos improve turn in, I would leave the rear
as standard and just do the bushes.

Regards,

The Gorilla.

Hey Gorilla.
U seem like the well of knowledge.

Is there anything from BREMBO for the CSLs O.E. front discs that just bolts on ???

Hah hah ! whats up Matt ? did you get pi$$ed off at me Saturday having a dig at you only doing 4~5 laps before having to cool you brakes off mate !!

Get some BBK on there and enjoy more of your track day!!
Nice meeting up with you, apologies for my appearance and all the Pigeon blood on my hands !! from

Yep, good to meet U too m8 and put a face to a name

U bird killer

Shame U didn't bring your CSL with Ya

No m8, not pissed off at all as the brakes were fine. Before U arrived I had a 20 minute non stop, flat out, Instructor laps and they were working great, without fade, if anything the brakes needed a lap to warm up

(the pads however, as great as they are, are at the end of their life now) They were 30% worn when I bought the car in October and have since done two TDs and over 2000 miles. I've ordered another set of the same, Performance Friction "Z" rated TD pads front & rear, all for a grand total of £140 delivered

That's what I call a bargain.

http://www.part-box.com/performance-...1058_1059.html

They are really superb, in conjunction with the braided houses and Racing Blue brake fluid. I'm just a little concern that as I build up speed & confidence in my CSL and as the ambient temperatures rise, I may need extra braking power come May/June time. I'm just thinking ahead and out loud about a simple solution that doesn't cost thousands £££ or require heavy modifications. I personally think the OE CSL discs can take the heat, however the OE callipers will start to complain, even with the PF pads, so a BREMBO four pot callipers, like the ones from the Porker 928 I think might do the job.

Over to Mr Gorilla

Hi,

The standard M3 CSL Disc are more than up
to the job, and at just 28mm thick you save
some weight as opposed PF, AP or Brembo at
32/35/36mm thick, about a kg a disc.

What you require is some 'Radial' Mount Calipers
either 4 pot or 6 pot that take a 28mm x 345/350
disc.

Porsche Brembos, 996,997 rears, BMW 850,
or something like a pair of Compbrake 6 pots
or Hi Spec 4-6 pots.

http://www.compbrake.co.uk/CALIPERS/..._PRORACE6.html

http://www.hispecbrake.co.uk/caliper...0Rad%20360.htm

Brackets would be around 80-100 each so for
under a 7/800 you can have a 4 or 6 pot set up
running your standard CSL Discs.

I am surprised that nobody ever did just a
Radial caliper kit for the E46 M3/CSL as
by spacing a radial caliper off the mounting
brackets you could have coverd
both disc sizes on both models etc
and retained standard front discs.

As 70/75 % braking effeciency is front
bias, then std rears with s/s lines good
pads and a rear balance valve mounted
in the cockpit for wet days etc, would
give all the brakes you would ever need
for a Trackday car.

Regards,

The Gorilla.

Top man... THANX for your insight. This is something I'm seriously considering as I've had GREAT! experience with BREMBO callipers in the past.
I think the reason no one did the Radial calliper kit for the E46 M3 /CSL is there's probably not enough money to be made out of it over , lets say AP Racing or Alcon BIG brake kits.

Any tips on who would be the best supplier of the before mentioned brackets ?

phat///M3 · 02-02-2010, 04:52 PM

Congrats on the new car Craig, I love e36s and this one looks like a great example.

The Gorilla · 02-02-2010, 05:23 PM

Hi,

MattCSLnut- www.BGdevelopments.co.uk
can make up Brake Caliper Brackets, or
Try www.Movit.de as they use to offer
Brackets for fitting Brembos to many
applications.

www.300mm.de also offer differing
BMW Brake combination applications.

Compbrake make Caliper Brackets, as
will your local CNC Shop with a sketch.

Its quite easy to work out once you
have the Calipers, and final disc size.

Surprised that somebody does not manufacture
a Standard caliper bracket with the holes drilled
for the hub centres, but left blank for the
caliper radial centres.

This would be for the std 28mm thick discs.

You then have brackets drilled and tapped
to suit your Caliper spacing etc.

Would allow several 4/6 pot 28/32mm radial mount
calipers to be fitted, while allowing them
to be quickly removed and removed to stock
for selling the car.

Regards,

The Gorilla.

Craig, SORRY for hijacking your post m8 but I have a further question for Mr Gorilla ( I'll start a fresh thread after this )

I have these "BREMBO" 4 pot callipers to fit onto my CSL. They are Porsche 928 S4, 968 CS, 911 (993 & 996 non Turbo) + Boxter 3.2 fronts. These are 25% bigger in overall size then the previously mentioned rear "BREMBO" callipers. The disc width spacing is 35 mm (as per pic 2) between the pad retaining clips... is that too much or is that OK ? Do U know if (with an appropriate custom brackets) these will fit over the CSL standard front discs ? THANX in advance
