Would be interesting to hear some feedback on the Spec-R diff.
The Spec R diffs are very bad. Strip the internal gears far too easy.
As for the 3 racing ones, if you are running the normal other gears then it is how you have built the diff. If you screw the blue end plate on unevenly you will distort the plastic gear. It will be build problem NOT product problem
