The Progress Technology rear brace assembly for 2002–2006 Acura RSX and 2001–2005 Honda Civic adds rear chassis rigidity to reduce flex and improve handling response. This model-specific rear chassis brace matches factory mounting locations for a direct replacement and helps provide more predictable suspension behavior under load for those model ranges.
