IFB8 REAR SHOCK SPRING 9.0T (HARD/2pcs)

The 9.0T rear spring represents a significant increase in stiffness compared to the stock spring (10.0T), providing enhanced support to the rear end during acceleration. This adjustment is effective for reducing rear grip, which can be advantageous in certain driving conditions. By utilizing this stiffer spring, drivers have the ability to fine-tune their car's handling characteristics.
