CSL v's M3 - Exact part differences needed!!

[Craig]

Hi folks,

This is maybe one for the CSL guru guy's, I need to know EVERY difference between the CSL and a normal M3. I'm talking everything, wiring looms, etc.

I know the following are different;

- Plastic Boot
- Carbon Roof
- Front Bumper
- Rear Diffuser
- Exhaust
- Sill Plates
- Seats / Door Cards / Centre Console
- Steering Wheel
- Wheels
- Engine & Airbox

But need to know what wiring looms are different, i.e ones leading the the steering wheel, and maybe tailgate? Ideally need to know every single difference right down to nuts and bolts.

I presume theres no major differences, and everything would be transferable from a CSL to an M3.

Thanks, Craig!

Let us know why your asking and it may make it easier to answer.

All will be revealed, I just need to check I can give details without implication myself or anyone else. I own a CSL and would like to know what parts vary from a standard M3.

You have wrapped it

Its a bit more complex than that, it's in the hands of solicitors fighting out the case. Once I've spoke to them tomorrow regarding posting pictures and information' i'll post the details if it's not going to cause any issues.

For the moment I need to work out if a payout is not recieved what I do as there are several parts left which are un-marked and could be either sold on or used in a re-shell. Even been considering building an E30 M3 w/ CSL engine and SMG.
