Buying Guide
What to consider when choosing a B18 twin disc clutch kit
- Goal and use case: Daily driving, street/track, or pure racing will influence hub style (rigid vs sprung) and whether a flywheel is included.
- Torque capacity: Most current options target up to 800Nm. Ensure your engine setup aligns with your intended torque range.
- Clutch hub design: Rigid hubs offer quicker engagement; sprung hubs provide smoother operation under load. Your preference and driving style matter here.
- Flywheel inclusion: Kits with a flywheel add mass and can impact pedal feel and idle characteristics. They’re beneficial for consistent engagement at high RPMs.
- Material and durability: Ceramic discs are common for their heat resistance but can be harsher on engagement. Aluminum clutch covers help with weight and heat dissipation.
Installation and compatibility considerations
- Ensure the kit is designed for B18, B20, B16 family engines in your Civic/Integra model range.
- Verify spline count (e.g., 185 x 24T) matches your transmission input shaft.
- Proper installation, including clutch alignment and flywheel resurfacing if needed, is crucial for longevity and performance.
Practical installation tips
- Follow the manufacturer’s torque specs for the pressure plate bolts and flywheel bolts.
- Use the correct clutch alignment tool to prevent misalignment during reassembly.
- Consider upgrading related components (pilot bearing, release bearing) if your kit recommends it.
Summary of key differences
- With Flywheel: Typically better for consistent engagement and track-ready performance.
- Rigid Hub: Faster response, more aggressive engagement; may feel stiffer on daily driving.
- Sprung Hub: Smoother engagement; more comfortable in street driving and daily use.
