I'm doing some research for an upcoming program...

As orginally supplied..in the UK

What tyres were fitted to E85Ms?

What front brake pack was fitted as standard /optionally

Was the sat nav standard?

What was the basic and best audio systems fitted?

Was extended leather just an option on Z4ms?
 
Tyres from memory, continentals?

Brakes are OEM CSLs, no options.

Sat nav extra

No idea about the stereo, used it once in about 14yrs.

Extended leather, not sure

  2. Brakes were 345x28mm front + 328x20mm rear, both with single-pot calipers. No upgrades/options were available

Many thnx 👌🫡
 
The Hi-Fi loudspeaker system had 10 speakers (option 676) and the Logic 7 was the DSP 10 speaker set-up (Option 677).

There is no mention of Extended Leather in the brochure I have for non-M facelifts.

All I can see is that extended leather was available in the 3L coupe, but not the roadster for some reason.
