The hub carriers that I ordered definitely had inserts set up for 2.5mm. That's why I was excited to learn that the RC10 inserts fit so well (after cutting to length). If there are 3mm-pin yoke inserts available, I'm all ears.
Thank you for measuring your arms!
Do you happen to know the part numbers for each?
To add some info:
-The driveshaft length measurement given is from the centre of the CVA joint to the centre of the drive pin for the diff.
-The rear arms for the current cars, use 3.5mm inner and 3mm outer hinge pins:
S3 arm is 73mm between centre of hinge pins, part# Z2-008RS3, or the graphite version Z2-008R3G
L5 arm is 75mm between centre of hinge pins, part# S4-008R5B, or the graphite version S4-008R5G
Note they seem to have added an "A" to the end of these part numbers now.
-Rear hub carriers for the YZ-2 3, 3.1 and YZ-4SF2 all have 3mm outer hinge pins.
The YZ2 hub with 3mm hinge pin is Z2-415RDC
The YZ-4SF2 hub with 3mm hinge pin is S4-415R
There are also Aluminum versions of each Z2-415RS2A and S4-415RS2A
The offset of the 2wd and 4wd hubs are different - 2wd hub puts the axle approx ~4.5mm further outwards than the 4wd hub.
