Lowering ride heights can leads to decreases of roll stiffness due to altered suspension geometry. Hardrace roll center adjusters, by extending the ball joints, raises roll center height and increases roll stiffness for better handling on lowered cars. This kit also includes extended tie rod ends to fix steering geometry, minimizing bump steer that often occurs after revising roll center heights.. Premium quality ball joint equipped. Increase roll stiffness on lowered cars. Improve front end handling & grip. Minimize bump steer  Note: 4 PCS/SET  Fits: Subaru Impreza 1st WRX GC/GF/GM 1992-2000 Subaru Impreza 2nd WRX GD/GG 2001-2006 Subaru Impreza 3rd WRX GE-GR 2007-2013 Subaru Impreza 1st STI GC/GF/GM 1992-2000 Subaru Impreza 2nd STI GD/GG 2001-2006 Subaru Impreza 3rd STI GE-GR 2007-2013 Subaru Impreza 4th GP/GJ 2012-2017 Subaru Xv/crosstrek GP 2012-2017 Subaru Xv/crosstrek GT 2017-2022 Subaru Xv/crosstrek GU 2023-Present Subaru Levorg 1st VM 2014-2020 Subaru Forester 1st SF 1997-2002 Subaru Forester 2nd SG 2003-2008 Subaru Forester 3rd SH 2008-2013 Subaru Forester 4th SJ 2013-2018 Subaru Forester 5th SK 2018-2023 Subaru Forester 6th SL 2024-Present Subaru Legacy/outback 2nd BD/BG/BK 1995-1998 Subaru Legacy/outback 3rd BE/BH/BT 1998-2002 Subaru Legacy/outback 4th BL/BP 2003-2008 Subaru Legacy/outback 5th BM/BR 2009-2014 Subaru Legacy/outback 6th BN/BS 2014-2020 Subaru WRX WRX/STI VA 2014-2021
