The 2011+ STI uses a sealed spherical bearing for the rear mount of the front lower control arm. This makes going to a hard urethane "ALK" bushing a bit of a downgrade. Therefore whiteline has developed this new kit for the 11-14 STI only, which uses an offset bearing to add caster, and uneven-sized spacers to alter the anti-geometry while still retaining a zero-compliance and sealed bearing.
Note: only fits 2011-2014 STI control arms. 08-10 and wrx arms use a smaller bearing housing. We have not yet confirmed fitment on the 2015+ but suspect these will work on both the new WRX and STI.
