OS Giken Differential Install

OS Giken differential install process for your Subaru BRZ, Scion FRS, or Toyota 86.

The OS Giken Super Lock limited slip differential is a high end product that will improve your cars cornering grip. This is the latest in my Subaru BRZ upgrades for competing in SCCA STX autocross. The OS Giken differential install process is fairly straightforward. However, it does take time and some familiarity with how the rear differential comes out of your car. With the OS Giken unit installed, you can expect improved grip during mid-corner and corner exit phases. Going fast requires putting the power down and the OS Giken differential definitely helps with that.
