Stage 3 Endurance - 500 ft lbs
Made from (Kevlar or Ceramic depending on stage). Designed to deal with more heat as well as torque. Engagement is not much different from the Daily option but this clutch can handle a lot more power and torque.
This system uses the same pressure plate as the Stage 3 Daily, but with disc designed for the needs of a circuit racing vehicle. The friction material is kevlar. This makes for a smooth transition between gears.

Best clutch I’ve ever owned
So far I’ve put 45k miles on this clutch @ 390 wtq, no issues whatsoever. From daily driving to street/highway pulls this clutch hasn’t skipped a beat. Brand new the clutch was super still up until 1,000-2,000 miles. After that it’s has lightened up a lot, but still has a super tactile feedback to it. Would recommend and buy again 10/10.
So Far, Not So Good...
I read nothing but amazing reviews for this, but my experience so far isn't lining up with them. I have 1,000 miles on the clutch and drove it very carefully the first 700 miles to extend the clutch's life and break it in right. I had it professionally installed at Growler Motor Labs (formerly COBB Plano). I doesn't hold the power that my 80k mile stocker held. Even my 390whp/380wtq E25 tune isn't anywhere close to the 500ft-lb rating of this clutch. It even slips on my very conservative 325whp/350wtq 93-octane tune. I'm pretty frustrated so far as it's been going on almost 2 weeks and I have had zero contact back from Southbend. I filled out the warranty request and have been in contact with Edge (who have been great, as always) several times. Southbend is keeping Edge and me waiting. And am I going to be covered for the $1,000 replacement labor for the faulty product? I hope so. It's too soon to tell - hopefully Southbend will finally get back to me and give me a procedure to bed the clutch that'll work and completely resolve my issue. At this point, however, I'm feeling regretful that I didn't go with the Mazdaspeed tried-and-true Act 6-puck. I chose the Southbend because it's supposed to last longer, but it's no good to me at all if it hold less power than my very worn stock clutch. Hopefully Southbend will finally get back to me with a sufficient resolution to change my mind about this experience, and I'd love to change my review at that point if possible. Time will tell.
NOT SURE WHAT CLUTCH TO GET
THIS CLUTCH IS GREAT. I WAS UNDECIDED ON WHAT CLUTCH COMBO TO GET OR STAY STOCK. I'M NOT PUTTING DOWN SERIOUS POWER(350WHP RANGE) BUT WANTED A RELIABLE CLUTCH THAT COULD TAKE THE POWER AND I COULD DRIVE EVERYDAY. I CAN'T SAY ENOUGH ABOUT THIS CLUTCH. THE PEDAL IS HEAVY AND TAKES A COUPLE DAYS GETTING USE TO. BUT IT HANDLES THE POWER AND I CAN'T BELIEVE HOW MUCH BETTER THE CAR SHIFTS, IT LITERALLY MADE A WORLD OF DIFFERENCE WITH THE SHORT SHIFTER. PROS: SMOOTH ENGAGEMENT, MUCH BETTER SHIFTING, HIGH QUALITY PARTS, CAN BE USED FOR DAILY DRIVING BUT IN THE CITY IT MIGHT BE A SLIGHT PAIN EVERY DAY. CONS: NONE AS OF YET, WILL BE CURIOUS TO LIFESPAN LATER DOWN THE ROAD.
For those who like OEM feel
So far I have a little over 500 miles on the clutch and I love it. It engages about the same as factory and has a slightly stiffer peddle feel to it. I highly recommend it. Make sure you pick up the throw out bearing as well as a pilot bearing because it does not come with either.
