35i & Z4M

Lol,l as googled
The ZF S6-37 is a 6-speed manual transmission manufactured by ZF Friedrichshafen AG. It is designed for longitudinal engine applications, and is rated to handle up to 370 newton metres (273 lbf⋅ft) of torque

E46 M3 is a different gear box as you say due to being to wide for the E85/86 transmission tunnel.
E46 330 is the same ZF as the Z4 in 3.0 and M although different ratios..

and in the S50 and S54 engined Z3M coupes a five speeder Getrag does the job. Try and fit a ZF from a E46M3 into a Z4 chassis, won't fit. Well it can be made to by chopping out part of the bulk head and transmission tunnel cover. Check the id numbers side by side. Even better, ask a BMW technician, err maybe not.
Hi, not trying to be smart, I'm a new guy around here :) But everything I've read over the last day or so has said it's a ZF in the Z4M.
Is that not the case?

Or have I misunderstood?

Something else I noticed almost immediately - the 'old school' hydraulic steering was very nice after owning 2 EPS Z4's. Wish BMW had stuck with hydraulic steering for the E85/86/89's. :(
