Customized Cyberlimbs
Standard cyberlimbs come with Body, Strength, and Agility
attributes of 3 (see Cyberlimbs, p. 335, SR4). While these basic
attributes are adequate for the average human or elf, they are underpowered
for the natural physiques of many dwarfs, orks, and
trolls—as well as exceptionally large and physical fit humans and
elves. Customization allow cyberlimb attribute ratings to be increased
by tailoring the limb to user’s overall size and musculature.
Since these customized cyberlimbs need to be designed to fit their
user’s body, they are more expensive than the basic models and are
not covered by medical insurances.
Customized cyberlimbs come with Body, Strength, and
Agility attributes that may exceed the standard cyberlimb attribute
rating of 3. Each customized cyberlimb may have a starting
Body, Strength, and Agility attribute of up to the character’s
natural attribute maximum (see pp. 62 and 73, SR4). Each point
of increment to an attribute above 3 raises the limb’s Availability
rating by 1 point and adds 1,500¥ to the final cost, but does not
take up any Capacity. Further increases above the natural attribute
maximum and up to the augmented maximum must be handled as
cyberlimb enhancements, with the standard Capacity and nuyen
costs (see Cyberlimb Enhancements, p. 335, SR4).
All other stats of customized cyberlimbs are the same as for
standard cyberlimbs (see Cyberlimbs table, p. 336, SR4).

Cyberlimb Enhancements: All cyberlimbs come with
Body, Strength, and Agility attributes of 3. These values can
only be augmented by cyberlimb enhancements—enhancements
from other cyber- or bioware systems have no effect.
Cyberlimb enhancements use up the Capacity of the cyberlimb
they enhance. The bonus to the enhanced value equals the rating
of the enhancement. Only characters with a cybertorso can
have cyberlimb enhancements with a rating higher than 3.
and i read that as meaning you can get a human arm with all 9's across the board without needing a torso . . .
maybe there's somehwere another hint at me being wrong, it has happened before, but at least now you know
(and knowing is half the battle) where to look for your interpretation of this very issue *snickers*
