Step it up to Warp 9 Titanium hardware! As a general rule Ti is 45-47% lighter weight than steel bolts.
Warp 9 Ti fasteners are CNC machined from Ti Bar stock, then the threads are rolled threads, not cut like some brands. This gives a stronger and smoother thread and also provides a more accurate torque setting. The heads on the axles and swingarm bolts are forged giving a far stronger head than standard CNC cut heads.
