Eibach makes the same Pro-Kit Springs for both the Scion FR-S and Subaru BRZ. The average lowering is about an inch for both the front and rear. In addition to looking great, the Eibach Pro-Kit provides a great balance between ride and overall handling. Compared to his BRZ on stock springs, my co-worker has noticed the following:
- The car feels like it is stuck to the road, especially when the road is smooth.
- There is much less body roll with the Eibach Springs and the car corners better. You can dive into a corner and feel very safe and comfortable with the car.
- The feel is very tight when going in and out of corners.
Eibach Pro-Kit FAQ:
What are the Pro-Kit's spring rates? The Eibach Pro-Kit Springs are progressive rate springs. Their rate varies with the amount of spring compression. The more compression, the stiffer the spring. Therefore, minor road imperfections cause less spring compression and will result in the springs working at a lower rate for a better ride compliance.
During fast cornering, hard braking and rapid acceleration you'll get dynamic weight transfer from front to back, and side to side. Greater weight compresses the springs more so they act at higher rates for better vehicle control.
The actual spring rate range is 48-200 lbs./in for the front and 103-274 lbs./in for rear.
