The rear sway bar has two mounting points in order to adjust the suspension geometry to increase or decrease body roll as necessary.
In return this sway bar will allow you to maintain oem endlinks, provide no rubbing/fitment/noise issues, and maximum suspension performance. The only change your BRZ or FR-S will experience is less body roll during fast cornering or over road irregularities.
Average installation time is about 30minutes with proper tools.
