I was looking around their E36M and regular E36 racks have 3.4 turn unit. I've been researching and I'm pretty sure it's suppose to be 3.2. Has anyone ordered their regular E36 rack from them?

for reference info I've collected ..
95M3 - uses 3.0 turns lock-to-lock
96+M3 - use 3.25 turns lock-to-lock
Non-M E36 - uses 3.5 turns lock-to-lock
Z3 1.9, 2.5, 2.8, 3.0 - use 2.7 turns lock-to-lock
MZ3 use - 3.25 turns lock-to-lock
the only one that does not share the same rack is the Z3/M version. they use the 96-99 M3 racks.
32131095575 is the same part # for all the z3's:

Z3 non-M racks are all the same.
- LINEAR ratio (same rack travel per input turn across the entire rack length)
- 53.5 mm of linear rack travel per 1 360 degree rotation input.
- 144.5 mm of total rack travel (translates to 2.7 turns L2L)
- installed 13.9:1 ratio
Z3 M racks and '96+ E36 M3 racks are the same.
- PROGRESSIVE ratio (rack is slower on-center, quicker towards L&R rack locks)
- 45.5 mm of linear rack travel on-center per 1 360 degree rotation input.
- 145.6 mm of total rack travel(translates to 3.2 turns L2L)
- installed 15.6:1 mean ratio
- Same p/n rack as E36 non-M, but locks were modified to shorten gear travel from 154.7 to 145.6mm
'95 M3 racks are the slowest and shortest of all US-spec E36 racks, until 200 deg of rotation from on-center.
- PROGRESSIVE ratio
- 39.0 mm of linear rack travel on-center per 1 360 degree rotation input.
- 117mm of total rack travel (translates to 3.0 turns L2L)
- installed 17.6:1 mean ratio
And btw, regular z3 rack > z3M rack = regular e36 rack
So the regular z3 rack would be the best

Thats what I read too. I was asking if anyone got their e36 rack from RD because they advertise it as 3.4 turn unit. I even sent the guy an email to make sure its a 3.2Comment
