Seeking CSL knowledge.

I think it's also for when driving in heavy rain (you take sport off which means it remains closed up to 5500rpm), where the ram air hole would send all the water in the intake.

Alex, this wouldn't make any difference. The lower air feed is always open.

The flap is also there for emissions cycle testing but its not needed for an MOT in this regard so can be ditched. Roof is a relatively easy change, four bolts and drilling out some spot welds on the OEM metal one and bolts and bonding for the CSL one. Windscreen type sealant works just as well as others although make sure you do a water test after. A few breakers get CSL roofs in but check to see how they have been removed before buying as if you twist the roof as part of the removal it will break down the lacer and go opaque in the sunshine. New roof from BMW is £1300 I think? We did one for an insurance claim a little while ago due to something being dropped on it by a builder.

You could fit a race roof but I wouldn't advise it, they are much thiner and not as resistant to sunshine or water.

Because they always break and serve no purpose other than to lower noise :thumbs:

Really? Why is that?

Kris, do you ever drive your car?:whistle:

Andrew.... yes i do and i have done a respectable 3 weeks of driving, in the last two years.... i kid you not!! Less is more is my motto!! :hahaha:

TBH i've so much upgrades that need installing.. spent £££s and it's all sitting in my flat. I think i have some sort of wierd fetish!! :whistle:

[Rutkowski]

Thanks you sir. :thumbs: Sounds like me and you have the same goal in mind. I want to start off with a M3 CS so the steering rack and other things will already be installed.

So you were able to get the OEM CSL air box to work properly?! Im going to have to PM you for the details because no one here in the states has ever made it work properly. They just install it and have the flap always open because they cant get it to open at the right RMP's and the idle is rough.

Yes the OEM CSL roof has been installed on a non CSL car. I plan on doing this too. Here is a link where daytonaviolet did it on his car. He knows a lot about anything CSL.

Good luck with your car. Will keep in touch. :beer:

And Max

Max, thanks for the link!! :thumbs: It's one of my next mods, it's been decided since i convinced my wife the sunroof spoils handling. (she wanted me to retrofit this!!!!):thumbs:

I never bothered with the motorised flap as they do go faulty and don't open, resulting in loss of power. By the time you know what's happeneing - you'll lose a lot of races...... that's my explanation anyway. :hahaha:

For the flap to work, you need to retrofit wiring loom and install the CSL software on MSS54HP ECU. The diagrams are available but i can dig it out for you.

Good luck!

Many of us CSL owners actually remove the flap :hahaha:

Max, welcome to the forum!

As Glendog mentioned earlier on, i have been turning my standard M3 2003, into a CSL. I won't go all out and remove sound insulation, sat nav etc but have, what i call - the must - have CSL parts. Steering rack plus DSC reflash, Wheels, engine specification (CSL cams and exhaust valves) MSS54HP ECU (all M3s beyond 2004 have it) CSL SMG software, Recaro seats, upgraded brakes, headers and Supersprint 'street' exhaust, CSL anti roll bars, alcantara steering wheel, M track mode retrofit and a few more bits.

The OEM CSL carbon airbox - installed and tuned by Evolve. Works exactly like on the CSL... perfect and smooth idle and start up. Highly recommended modification. :thumbs:

Good luck with your project and as for the CSL carbon fibre roof - i'm still in two minds about it.... cutting out mine and installing CSL one so the car is rigid.. is it possible? How is it done on the CSL? What has BMW used to bond that roof?
