      Great clutch

      Great clutch... with a learning curve.

      This is a great fast driving clutch. It's not optimized for stop/go city traffic. In first gear, it has a fast/slow "hook," meaning you engage the clutch quickly, but slow down as it bites. Conversely, dropping out of first is counterintuitive, at least for me - you have to disengage it slowly, if you don't want chatter. Once you understand it, though, it's fine - it just can't be "feathered" - needs attention from you to decide if you are speeding up or slowing down. From second gear and up, it's just fabulous. I can shift really fast on the highway, moving out of traffic, while other drivers are just thinking about it.

      Spec stage 2+

      This Replaced the stock clutch and it got rid of the chatter. Installed light weight flywheel, braided line, and ford racing throw out bearing. Have almost 900 miles on it since summer 2023 and it bites hard and holds the added power. Would give 5 stars but I get a squeal from time to time in 1st gear from a stop. Might be TOB but shows no signs of slipping

      BEWARE, THIS IS NOT FOR DAILY/NORMAL DRIVING

      Yes, this clutch can hold up under load and at high RPM shifts but that is the main reason why you should not buy it if your build is not for racing. The whole assembly, with the matching SPEC steel flywheel, is longer than the factory one which will take up more space in the transmission bell housing area so the transmission is super hard to fit back on. Most people in these reviews are not saying that. I was under the impression that this clutch could be used in daily driving situations, but it really can't. You will stall a lot because it is hard to get into 1st gear without the whole drivetrain shaking violently, and reversing is the same way. It does make a lot of noise, more heat in the shifter box and vibrations in the shifter as well. Chatter when decelerating and mainly in third and fourth gear does not go away after the break in period. Like I said, stay away if your car is not for racing and I am disappointed more reviews did not say this about the clutch.

      Amazing clutch grabs nice.

      Had the clutch installed with a billet steel flywheel. It’s really good compared to oem. the clutch does grab wicked hard during the break in but gets better. I’m daily driving on it right now. I’ve experienced some chatter but it’s only after I drive for a long period of time, sometimes I don’t even hear it. Everything was torqued to spec new bolts and lock tite. Really no issues other than some chatter.
