Why Upgrade to ACT SB011?

Common turbo issues:

• Clutch slip under boost
• Weak clamp load from stock pressure plate
• Heat fade during aggressive driving
• Inconsistent engagement

ACT Fixes That:

• Increased clamp load for higher torque capacity
• Improved pressure distribution across clutch disc
• Better heat resistance under repeated load
• More consistent engagement feel

Translation: it actually holds boost now.

ACT’s performance pressure plates offer many advantages over stock pressure plates. The original single diaphragm design maintains the right kind pressure plate geometry, which supplies a smooth and precise feel that may be positive and firm, extends snatch life, and increases clamp load.
