Type: Both clutch and flywheelBrand: Jim Wolf Technology
Models: They only make one. Part number L3503-NC000 for the clutch and L3503-NF000 for the flywheel
Pros: Noticeably quicker revs and acceleration, better engine braking. Maybe as much as 40-50% quicker than stock. Rides pretty much the same as OEM.
Cons: A bit tricky to engage properly for comfortable daily driving, especially from a stop and from first to second. I have to slip it a lot, the engagement point is about halfway out, but it seems to fully engage only at the last minute. Could just need an adjustment, though.
Comments: Much different feel from the stock clutch, which is too mushy and not responsive enough for my taste. You can also feel vibration in the clutch pedal more. Of course there is a bit more noise below 2000 RPM, typical of aftermarket clutch / flywheel combos. I'd say it's a good choice for a street car that sees some autocross / track use, or for someone who wants a bit stiffer clamping force, though I have not tracked my car. I'm not sure how much HP / Torque this combo can reliably take but I've heard they are quite durable. Infiniti mechanic said it would last longer than stock! Overall I'm satisfied and I think this combo is well worth the money.
