CSL keyring dimensions and photos

[NZ_M3]

Okay, I have been thinking about making a replica keyring (or a veriation of it in carbon) for myself ... I have actually already made the carbon insert, but I sort of need the dimensions and what the back of the keyring looks like. Would anyone here with one be so kind as to snap a few photos of the front and back of it and perhaps provide some overall dimensions, thickness and the size of the "M3 CSL" insignia for me perhaps?? Thank you : )

Watch the market get flooded soon :hahaha:

You could borrow mine for the weekend... however I've never been fortunate enough to get my hands on one (yet)

Hi Tom.

The keyring shape (as also on the E46 M3 keyring) resemble the front fender grilles shape.

Here we go.



The thickness is 4mm.





The main issue of the CSL keyring is the weight.
It is too heavy, unlike the rest of the car.

What are you considering doing ?
I would love a CSL keyring replica made of aluminium.
I have a friend that designs and produces various cnc-machined parts (top mounts etc).
Should I ask him to design it in CAD and then we could produce some of them which would be superlight ?

I'd love one of these. Would it possible to make it aluminium with some kind of carbon inlay?

Like the original

Like the original

So why would it be any lighter than the current one?

It is not aluminium but some iron alloy (soft).

I've got an M3 one and it seems to work ok

Alternatively, skip the desert course or have a good shit before your hot lap ?:smokin::thumbs:

to be honest I like a nice heavy keyring, makes it feel high quality rather than potentially flimsy/cheap

That is fantastic Alex!!!! :thumbs::thumbs::thumbs: Exactly what I need!!

Intention was to make the thing out of carbon with a replica "M3 CSL
insert in some sort of alloy perhaps.

One question thought ... the height you have it as 18.5mm on the right hand side ... but when you add the figures together on the left hand side 6mm+4.5mm+6mm = 16.5mm?? I am presuming perhaps one of those numbers should be 5.5mm or 7mm even??

I presume the OEM item is so heavy perhaps due to it being made out of stainless steel rather than alloy?

It is corrected now.
Pay attention that the side is curbed so the 18.5mm is including the curve while at the edge (without the curve in the middle of the side part) is 18mm.

I don't think it's stainless steel. It's damaged too easy to be stainless steel. I could be wrong of course.
