M30 with Getrag 240, clutch does not engage

[MiWision]

Our E30 has this spec:

M30B35
Getrag 240
M10/S14 lightened flywheel from RHD, 228mm
M20 pressure plate with 30% more pressure than stock
S14 Sachs Motorsport clutch (1862168232), 228mm
M20 slave cylinder
M10 release bearing

Our problem is:
The slave cylinder does not have sufficient length to push down the clutch fork.

There is a gap of about 15-20mm as the clutch fork can move before it is pushing the pressure plate. The clutch pedal only takes the last 20-25mm before the clutch pedal reaches the floor.

What could have caused us to get this error? Do you have to weld spacers on relaease bearing in order for it to work? How have you done?

E21 323 m20 throwout bearing gains you back about 8 mm, if that helps.

The problem may be the 228mm pressure plate with the 215 throwout-
the 215 pp is significantly deeper than the 228, and if the s14 friction
disc is thicker, you could very well be running out of travel.
The 215 throwout usually works with an M10, 228 stock clutch and friction disc.
But it's shorter than ideal.

Personally, I might, in a fit of 'make it work' take apart a slave, and make
a somewhat- longer pushrod for it.
