I wish I knew where the 6-bolt 30-spline setup came from. My vendor snatched it up from Japan and the vehicle source was lost in translation.

For my 300HP power level, I chose to stick with the S15 HLSD, 5-bolt (10mm hardware) 30-spline shafts and matching J30 axles. I think this is a reasonably stout setup. I considered going with the Z32-TT / Q45 axle setup but just felt it was excessive, especially since I'de still be running an R200.

Here is what appears to be R34 GTR output shafts. Its quite possible that they are 30-spline and the same diameter and fit the S15 HLSD. See attached photo.

One thing I just thought of, it may be possible to take the 5-star J30 axle, then take a 6-star Q45 axle -- disassemble and swap flanges. If this would work, this would allow you to run the 6-bolt setup without having to hunt for Z32-TT LH axles.

Another thing to note, the second photo I am attaching is from the Sillbeer project car, they used an R33 GTR differential -- but swapped the input flange so that it would work on an S-chassis. I have no idea what is inside the R33 GTR differential or what spline count the output shafts are. I'de have to check my FSMs and I dont have them on this PC.
