We did a PERRIN PERFORMANCE Sway bar install yesterday on a customer’s 13′ Subaru WRX. This customer had taken his bone stock WRX out to an Auto X event and wasn’t happy with the inherent understeer on the vehicle while driving at the limit. He came to us for setup suggestions and advised that the 22mm 3 way adjustable Perrin rear sway bar would be a great place to start. Started him off in the middle setting on the bar and then we will be tuning from there. After initial test drive customer stated “I can’t believe how much more planted it feels and yet the ride comfort seems unchanged. This is too much fun!” Simple, cheap, and great results. If you are looking for help with your setup, send us a message or give us a call and one of our experts will find the perfect part for you.
