Fits 98-05 Lexus IS300 and Toyota Altezza SXE10. Fits 05-2012 XE20 IS250. Bolt on solid bushings replace old worn out OEM parts that wont let you get the power to the ground, and they outperform / outlast urethane often at a lower cost too. This CNC machined, CAD modeled 6pc alodized aluminum set fits perfectly due to 3d laser scanning and probing of the OEM subframe and diff. these are great to install at the same time as the sub frame risers, sold separately. Some people with older cars actually get less noise from the drivetrain because they didn't realize just how bad the original bushings had become despite solid mounts naturally transmitting more noise than rubber. Check the gallery for installation orientation of each piece.
