GKTech Lexus IS300 Rear Subframe Braces

The factory rear subframe braces on the IS300 are made from thin sheet metal and allow unwanted flex under load. The GKTECH Rear Subframe Braces are designed as a direct replacement, increasing rear-end rigidity and stability.

Constructed from high-strength chromoly steel tubing, each brace is CNC machined and TIG welded for maximum strength and precise fitment. By limiting subframe movement, these braces help maintain consistent suspension geometry, improving traction, handling response, and overall driver confidence—especially during aggressive driving or track use.

A simple bolt-on upgrade that delivers a noticeable improvement where the chassis needs it most
