By removing the spring placed in the parking brake lever, you can easily use the parking brake to induce and/or maintain your drift. With the PERRIN Drift Knob, the parking brake lever will not lock and will return to the off position automatically. Made of machined 6061 aluminum or stainless steel, the Drift Button is either black anodized aluminum or brushed stainless steel. Each button features a large lip to easily lock your parking brake in place. Each PERRIN Drift Button is also designed with OEM usage in mind. If you would like to keep the OEM parking brake spring installed for an aftermarket look and standard parking brake functionality, you can do so with no modifications required. Installation is as easy as unscrewing your existing OEM parking brake button, removing the existing spring (if you choose), and screwing the PERRIN Drift Button into place.
