interesting indeed, thanks for the link.
strange that he doesn't seem to know the answers to some questions. example; the thinner walled exhaust.

Hi,

Its a shame that they did not have all their
facts correct, and that some of their Audience
were better informed regarding the CSL,
than the Men from BMW !!!

PR Spin is replacing the Old School passion
at BMW MS for sure.

Regards,

The Gorilla.

Aluminium rear control arms?! I didn't know... The regular ones are so heavy. I can only imagine how hard that would be to find.

Hi,

Quote - ''.....enlighten us why you think the CSL engineers got their facts wrong.

CSL shares the same Camber / castor as the M3,
CSL Exhaust metal is thinner [already stated]
CSL Header material is thinner than M3 [but is
now supplied as std since 2005] CSL rear trailing
arms are the same as std M3, only BMW MS and
ALMS Cars ran Titanium rear arms, CSL Bare Shell is same
as M3 apart from less seam sealer, CSL does
not have Lighter boot floor, CSL rear windscreen
is 3mm not 4mm Glass same as the rear side windows,
and other items as well.

You would have though that ''Technical'' CSL Engineer's
who allegedly worked on the CSL project
working for BMW and making a presentation at the
recent CSL gathering in Munich would have known
all the above, but alas no.

As I said PR Spin is replacing true MS passion.

In World where ''Accountability'' and ''Integrity'' are
almost extinct then are current and future generations
really concerned ?

So why donīt you apply as an official M spokesman? then years after one big development you can tell us all the little changes and proclame yourself a technical master

BMW do not pay enough and I am
more than happy with my own CSL.

don't tell it again, instead of shitting on people and acting like you know everything, maybe just enlighten people politely that some of the info is possibly incorrect. Come in here like a pompous douche bag instead...

lol, cool your jets. so the engineers forgot some things from 10 yrs ago, and some errors were highlighted.

working in the automotive manufacture industry, i can categorically state that the enthusiasts are much more passionate about the cars than the designers / engineers.

Funny old world, Guy asks to be enlightened
on why BMW in making a presentation gets
some items incorrect, reply posted, and then some
''Moosehead'' kicks off.

Try reading the sequence of posts and their content
before throwing insults around.

For the record several colleagues attended the
Weekend/Presntation with their CSL's and
had very mixed reviews.

The point being that given the CSL ''Project''
was developed during 2002 then the age
of one the Guys making the presentation
in Munich was a bit of a giveaway.

The Gorilla.

You're wrong on a couple points The CSL does have more aggressive camber and caster according to its alignment specifications. The steering knuckle is a different part number; they could have easily accomplished the changes there. I don't see any mention of trailing arms. The camber arms are frequently referred to as control arms by BMW.

I also imagine these engineers have worked on other projects in the last 10 years. I'd be surprised if they remembered every single detail, especially regarding thickness of various items. They didn't say that the exhaust was the same, they just said they weren't sure.

One incorrect point I did find was their claim that the engine control unit is more powerful. It isn't. The CPUs are the same as any E46 M3 (and E39 M5). Compared to 2003 and earlier M3s, the CSL's MSS54HP has twice as much flash (90% of which goes unused), and an extra driver to control the intake flapper. Compared to 2004+ M3s, only the flapper is different.

(There may be some other very minor hardware difference between some MSS54s and the MSS54HP, since some throw an internal error when running HP code)
