Considering there is so much contraversy over F1 products ive decided to purchase a stage 2 clutch and their 11.5lb chromoly flywheel and write a review on it. So first ill start with customr service. i ordered my clutch and flywheel from Gripforce.com for 250, and paid for the 2 day shipping. it arrived the second at around noon. Everything was packaged well including the clutch, pressure plate, throwout bearing, install tool and flywheel. No visual defects or damage. The clutch disk has good contruction. nothing loose. rivets nice and tight. torsion springs are stiff and secure. the flywheel is perfect cut and has a tight press fit pilot bearing. Ive installed the clutch and flywheel and now have 100 miles on it. Pedal effort is small with the stage 2. the clutch grips very well. either semi short or really short if you drop the clutch. slight clutch chatter was noticed during the first 50 miles, as a lot of clutches do during breakin. No more clutch chatter is present. Throttle response with the flywheel is amazing. definetly noticed over the 22lb stock flywheel. Overall this product is GREAT for the money. i would recommend it.

I can vouch for the stage 3 6 puck for the 3rd gen. I'm at about 4k miles on it now and works better than ever. Crazy chatter during break in, but it does well now.

Yupp. Chata chata. Its like the crank and main shaft are sayin "hate hate hate hate hate hate" at the beginning. Youll get more if your running a lightweight flywheel as well.

Luzer gave me advice to drop it from 2 or 3k to get going from a stop and that helped with the chatter during the break in. Realistically my break in period lasted like 1500 miles. That's a rough idea of how long it took for the clutch to become comfortable to DD on.

I had an F1 Racing stage 2 clutch and it sucked. It didn't even last me 500 miles on my freshly built b20a. The clutch disc tension springs broke. I must admit I raced my lude one time with my new clutch with at least 400 miles on it. But either way it shouldn't had fucked up like that. I'm running an OEM Exedy clutch now and it's perfect. I wouldn't recommend this clutch to anyone.

I'm hoping to get a full life out of this stage 3. It was used by rev_rage and I can't vouch for his full experience with it, but so far so good here. It was good for my budget at the time.

I can't speak for your springs but what you posted in 3rd gen was you babied it from the beginning. I on the other hand did many moderate to severe drops from the beginning. I am pretty sure my stage 3 six puck sprung clutch from f1 was ceramic. I also purchased a f1 racing 9.75 integra one piece chromoly fly at the time. Mine is great still. My only complaint is that the combination of the the two are little too much to deal with in stop and go traffic on the freeway where you have little area to move forward. Also that lightweight of a flywheel adds several hundred rpm to drop it in at to keep it running. I would say an additional 350 -500 rpm. Hopefully in the next day or so I can find out if I can increase idle by about 400 rpm and it still run right. I tried one method like the book says but that didn't do the trick.

I have not done alot of research on breaking in clutches just what I heard here and there. I know if it is anything like my hawk ceramic pads for the brakes, the manufacture says right on the box to do like 10 moderately heavy stops at like 40mph then like six all out slam the hammer down at like sixty to break them in. I just did this last month and they work great. Hawk box also said not to ride the brakes while breaking them in. I am not saying you didn't get a bad product but I would be curious what your flywheel looked like when you opened it back up to replace the f1 clutch. Was it stock flywheel and if so did you have it resurfaced while installing the f1 clutch? If not stock flywheel was it an f1racing lightweight flywheel?

Well, I drove nearly 1000 miles on my f1 stage 2 without giving it over 50 percent throttle. Break In AND installation is key. I currently have e around 8k on it now and it's great. The only one issue is that sometimes, especially in cold temps and initial start up it it grabs slightly as soon as I release the pedal and pulls the car forward until engagement and I think that's from when I installed it I didn't put very much high temp grease on the main shaft cause I was worried about contaminating the clutch disk so the disk sits toward the pressure plate side when it deos that.

Mine does that too!

Update on mine, I've put over 10k on it and it's running strong, it takes abuse.

I put in the stage 1 and 11.5 flywheel after my clutch went out. Been running it for over 25,000 miles and it still works fantastic.

Glad I read this review, i'm picking up a stage 3 sprung clutch and 11.5 flywheel soon. I had a stage 1 exedy a few times now and I have had great success with them. Once I ran a 8.5lb flywheel... never again. Way to light, 11.5 was the next flywheel I ran it was perfect. I just need to beef up the torque capacity and for the price, you can't beat f1. Everything else close to 300lb's is $400.
