Not necessary but well received
Last season I autox’d my Brz during the practice days for events and have decided to do it competitively this new year. With that; som light suspension tweaks and new tires would be well received by anyone wanting some more confidence in the car. The quality of the Perrin brand has always been a plus and was happy with the finished outcome. Instructions are a little backwards with removing the oem bar; but just in a convenience way. I would recommend any of Perrins sway-bars.
