The ISR full subframe solid inserts are a set of solid subframe replacements for Nissan S13, S14 and Z32 platforms intended to eliminate subframe flex and restore a more direct chassis connection. These inserts replace factory subframe bushings to provide a firmer subframe mounting interface for the specified Nissan platforms. Verify your chassis and model year to select the correct insert set for S13, S14 or Z32 applications.
