Kartboy Rear Subframe Lockdown Bolts 2002-2007 WRX / 2004-2007 STI

The Kartboy Rear Subframe Lock Kit is designed to eliminate unwanted movement in the WRX’s rear subframe during aggressive driving.

This kit helps lock the subframe in place, ensuring consistent suspension geometry when it matters most.

• Locks rear subframe to reduce unwanted movement

• Simple, bolt-in installation using basic hand tools
  
• Noticeable improvement in rear-end stability and response
