Spec Clutch SL55ET-E Super Twin Clutch Kit Lotus Elise Exige 2ZZ-GE

The Spec Clutch SL55ET-E Super Twin is a dual-disc performance clutch kit engineered for high-output Lotus Elise and Exige applications running the Toyota 2ZZ-GE engine. Designed for competitors and serious performance enthusiasts, the Super Twin platform dramatically increases clamping force and torque capacity while splitting the friction load across two discs — allowing for a more manageable pedal feel relative to single-disc setups at equivalent power levels.

Key Features:

• Dual-disc (twin) design for significantly increased torque capacity over single-disc alternatives
• Street/track-oriented engineering balancing aggressive holding power with drivability
• Spec proprietary floater plate sandwiched between twin friction discs for even load distribution
• Machined billet pressure plate with heavy-duty diaphragm spring for consistent clamp load
• Sprung hub discs available in Spec's Extreme (E) friction compound, formulated for high-temperature performance and longevity under sustained track use
• Compatible with stock or lightened flywheel (verify fitment with Spec for modified setups)
• Includes all necessary hardware for installation

Spec Clutch's Super Twin series is purpose-built for builds that have outgrown conventional single-disc solutions. The SL55ET-E is an ideal upgrade for supercharged, turbocharged, or high-revving naturally aspirated Lotus powerplants where reliability under sustained high-load conditions is critical.
