They also now sell a "anti-squat reduction weld in kit" for the S13/R32 subframe (maybe that's why people are going back to S13 subframes?):

In conclusion, the main reasons for S14 rear subframe design updates are ride comfort related. There are more rubber bushings and the lower arm and toe arm ones are longer for more bushing compliancy toe-in action under load.

The S13 rear subframe is better suited for use in drag racing at OEM ride height and can be used in the circuit racing too albeit the ride height must be reduced significantly, but that will cause other problems to occur.

The S14 rear subframe is better suited for use in circuit racing with its low anti-squat, but it is recommended to raise it as close to the chassis as possible for some gain in anti-squat for better traction.
