FEEL'S HONDA TWINCAM COPPER MIXTURE CLUTCH SET FOR HONDA CIVIC EG6 FEELS-00393
Here are some of the technical advantages claimed (or reasonably inferred) for the FEEL’S Honda Twincam Copper Mixture Clutch Set (e.g. FEELS-00393 / similar “Copper Mixture” series) when used on a Honda Civic EG6 (or equivalent EG chassis).
Claimed / documented features & advantages
From product descriptions (for sibling FEEL’S “Copper Mixture” clutch sets) and what they market, the advantages include:
- High heat resistance / warp resistance
The clutch is described as “extremely resistant to warping due to heat.”
In high-load, high-rpm driving (e.g. track, spirited driving), clutches get extremely hot. A clutch material that resists thermal deformation helps maintain consistent engagement and avoids clutch disc distortion. - No judder feeling, stable engagement
It’s claimed there is “no judder feeling,” and that the clutch performs better than non-asbestos types in that respect.
This translates to smoother engagement transitions, reducing chatter when releasing or depressing the clutch — helpful especially in low-speed maneuvers or when modulating clutch. - Strong connection even at high rpm (high slip torque capacity)
The marketing material says “outstanding connection performance even at high rpm” and that their burst test exceeded 12,500 rpm.
This suggests the clutch can hold under higher torque inputs at high engine speeds without slipping, which is desirable for performance builds. - Reinforced cover with high clamping (crimping) force
The clutch set is bundled with a “reinforced clutch cover with a crimping force of 600 kgf/mm” (i.e. a stiff pressure plate).
A stiffer pressure plate helps maintain consistent clamping force under load, reducing the tendency for the clutch to slip under torque load, especially when driven hard. - Material improvements: fade resistance & abrasion resistance
They mention “a new material with excellent fade resistance and abrasion resistance.”
Fade resistance means less drop in friction under repeated application/heat cycles. Abrasion resistance means longer life under wear conditions.
What these advantages imply in practice (for EG6 / Twincam use)
- You get more torque capacity margin over stock clutches, which is useful if your engine is modified (camshafts, higher revs, more power).
- Less risk of clutch slippage during aggressive use (e.g. rapid shifts, launching, high rpm).
- More consistent pedal feel and engagement even after repeated heat cycles (e.g. track days).
- Potentially longer service life under harsher conditions compared to softer “street” clutches.
- Because the clutch is designed to avoid warpage and maintain consistent contact surfaces, the engagement point and feel should remain more stable over time.
Important caveats & considerations
- A “copper mixture” or high-performance clutch will likely have a higher pedal effort / stiffer feel than a stock or milder clutch. That’s typical of performance clutches (not always stated explicitly).
- Noise, vibration, or harshness (NVH) might increase (e.g. more chatter under light clutch engagement) — though FEEL’S claims to mitigate that (“no judder”) in marketing.
- The clutch must be matched to the engine’s power and driving usage — overkill or mismatch can lead to poor drivability.
- Installation quality, flywheel condition, alignment, and clutch hydraulics (master, slave cylinders) all play a big role in realizing the potential.
