my M3 CSL
 
I started sometime ago a calendar type thread about my CSL which I stopped updating.
I think I will put this calendar here and start posting the updates here ;)

A few things about my CSL.
My CSL is a Swiss version CSL, it has been sold and driven June of 2004.
It has automatic clima, rain sensor, radio cd, xenon lights and speed limiter removal.
Being a Swiss CSL also means it does not have the front license plate holder, as our plates here are tiny and amazing !

I got my CSL October 2008 with 44k km on the clock.
It had one owner.
It's a Silvergrey car (the fast ones)

http://www.clubcsl.com/images/clubcsl/m3-csl-home.jpg

Today the car has 92k km and a few modifications.
- AP racing front and rear brakes (front CP5555 with PF discs and Pagid RS14 / rear AP calipers with OEM discs and Pagid RS14)
- Powerflex ARB bushes front and rear
- GC racing front wishbone bushes
- Powerflex rear trailing arm bushes
- Supersprint Race lightweight backbox
- Ohlins TTX suspension with GC front top mounts, GC front ARB drop links, AST rear top mounts and Eibach springs
- Recaro bottom cushion in the driver's seat

Here are two photos of the recaro cushion
It turned very good, as I am tall.

Working on the rear brakes.
The securing bolt had been damaged and I had to get it out the hard way.
Lost many hours.

http://www.clubcsl.com/CSL/blog/DSC00150.JPG

Then, I installed new OEM discs and Pagid RS14 pads.

I created an AUX IN module and then connected it to the radio cd.
The circuit is quite simple and costs around 15 EUR to make.

So on 31st August 2012 I started the big project of replacing all the bushes and spherical joints of the rear axle.

Here is the picture of the cracked bush.

The axle is out.
Getting ready to remove the rear suspension.

http://www.clubcsl.com/CSL/blog/IMG-20120905-00453.jpg

In the meantime, I will remove all the rust and repaint the parts.

The bolts adjusting the camber had seized.
After a lot of hours... I cut them out.

Courtesy of my brother, I received the special tools of BMW and replaced the bushes.

A heatgun is needed.

The rear axle carrier needed quite some work to take the rust out and repaint it.
Here with the antirust color

http://www.clubcsl.com/CSL/blog/IMG-20121017-00016.jpg

Then painted black.

I installed the new bushes (original BMW).

http://www.clubcsl.com/CSL/blog/IMG-20121021-00035.jpg

Then I started the assembly.

I bolted the 4 arms (aluminium ones).
Then I put back the axle carrier on the car.
Next was the differential ($*#$#*$U*#$U heavy !!! :moan: )

There was a recall for the differential bolts of the M3 E46 & CSL, as the original bolts were breaking.
On the left the new bolt (it doesn't have threads throughout the length) and on the right the old bolt.

I installed the new bolts.

http://www.clubcsl.com/CSL/blog/IMG-20121023-00045.jpg

I also replaced all other bolts with new ones.

alexk 04-07-2013 07:06 PM

31.10.2012
 
Everything was bolted back together.
I also changed the rear ARB drop links and the brake fluid.

Two months later and the car is ready... :)

Beautiful car Alex, I have seen it in Munich:thumbs:, Nice too see you do a lot of work on your own.

0-60Motorsports 05-07-2013 08:36 PM

Beautiful CSL. Where did you get the recaro bottom cushion from?

Loaded 11-07-2013 12:04 AM

Great effort Alex and the results looks excellent!

Best

Couple of pics after cleaning both cars with clay and polishing.

They look shiny now.

I don't drive the car very often, but last time I had the gremlins of the alternator coming out (battery light coming on/off randomly) so I decided to take it apart.

http://www.clubcsl.com/CSL/blog/20131214_193216.jpg

Here is the evil part :)

http://www.clubcsl.com/CSL/blog/20131214_193228.jpg

Took apart to see if the contact rings and contacts look ok.
I suspect the voltage regulator. I will consult my brother.

Nice work mate :smokin:

Looks like a nice day spent!

Nice work Alex.

Equinox 15-12-2013 01:41 PM

There are worse things to be doing than working with BMW's Greatest engines.

0-60Motorsports 20-12-2013 01:34 PM

Beautiful cars. Love that Recaro cushion. How much did it cost you?

digi 20-12-2013 07:36 PM

dame - nice work.

So back to the rebuild saga.
Here are the thermostat tests -> thread

Now here is the picture of my radiator.
A lot of dirt. No wonder the cooling system was not performing good.

http://www.clubcsl.com/CSL/blog/20140313_210610.jpg

More updates to follow in the next days.

A busy weekend but managed to do a lot of things.

Here is the old vs new water pump.
The new pump is slightly different inside, where the bushing is. Also the geometry is slightly different inside. Maybe the flow will be be better (?).

http://www.clubcsl.com/CSL/blog/20140315_192811.jpg

Here the water pump installed, with new pulleys and belts.
Also new thermostat and water hoses. Just being proactive with the water hoses.

http://www.clubcsl.com/CSL/blog/20140315_203549.jpg

The oil radiator was more dirty than the water radiator.

http://www.clubcsl.com/CSL/blog/20140315_220332.jpg

Here both radiators after cleaning them.

http://www.clubcsl.com/CSL/blog/20140316_095817.jpg

Here is the front mask in an AC equipped CSL.
It is visible that it is blocking a lot of air.

http://www.clubcsl.com/CSL/blog/20140315_214106.jpg

There are also these silly ducts (like in the efficient dynamics newer models that close when not going fast or stopped).

http://www.clubcsl.com/CSL/blog/20140315_214115.jpg

Just check here how much surface the fan base and fan itself are blocking.

http://www.clubcsl.com/CSL/blog/20140315_214718.jpg

I binned the fan and here is the end result (like in the non-AC CSLs).
The fan is 4.5kg so another weight saving.
The problem will be if you want to use the AC when stopped in traffic, but I don't mind as I never do this.

http://www.clubcsl.com/CSL/blog/20140316_104259.jpg

Also, I binned the fan and the fan shroud (more weight savings).
Another 1.8kg saved here.

http://www.clubcsl.com/CSL/blog/20140316_122115.jpg

Then I put the car back together and started it.
It will be interesting to see what happens next time I have a trackday and it is hot.

shimmy 16-03-2014 09:52 PM

Alex.........superb, you are a brave man,.

alexk 24-06-2014 08:54 PM

I have many updates on the temperature issue topic.

I will come back to you in a week or so.
Need to sort the bloody front top mounts etc.

Very interested to hear this.

I've recently swapped out my rad to a new OeM rad and also put in a new viscous fan clutch thingy.

Graham 26-06-2014 05:22 AM

Very interested to hear the outcome.

Does your a/c still work?

Visibly it looks like it will make a big difference to running cooler.

Interesting.

How do these flaps work then? Are they attached to a servo?

I meant when driving along you'll get a lot more airflow to the front of the road :thumbs:

But it is the sitting in traffic bit that worries me
