Hey there everyone, 
Spring is around the corner, and I know many are considering what upgrades to do before it gets here.
For those of you who are considering a new LSD for your car, I have a a great deal to offer you on a Brand new OS Giken Limited Slip Differential.
The OS Giken is unlike any of the other differential options currently on the market.  A progressively ramping differential which means no harsh uptake on either the acceleration or deceleration side of the differential. 
Unlike most other options, which utilize either a 6 or 8 plate setup interally, the OS Giken uses 28 plates (2 deactivated)  This gives this differential unparalleled durability, and performance.
If you are considering a upgrade and have questions, I am always here to help.  I don't always remember to check my email here though so please either give me a call directly or email me directly, and I will be sure to get back to you as soon as possible. 
Best Regards, 
Erik Johnson
