Anyone regret twin disc clutch?
 

As the title, has anyone whom had put in a twin disc clutch in their fr-s/brz/gt86 regret it?

After increasing torque my current clutch it balancing on the edge of slipping and wot is useless. I'm currently looking at buying another clutch this time with a bit more headroom than what I have currently, ending up in the 500whp club. I don't see going anyhigher with the stock trans. I also, don't really have any gripes about my current clutch other than the lw flywheel chatter, which I'll be going back to a regular flywheel when I swap it. I've already picked up velox's clutch fork and pivot point too.

Every person I have met in person has regretted going twin disc. Talk to Action Clutch about there BRZ/FRS clutch's.

Well if it's anything like my OS Genkin twin plate on my MR2, it's not recommend for daily driving. At lest comfort wise it's not. Super stiff, more like an on/off switch for gears. Not sure if you guys have the infamous twin plate rattle. I once pulled a hammy while driving to LA for the weekend and got stuck in traffic.

That's why I made my MR2 into a weekend/track car instead.

Pretty much the same as what mrk1 said. For daily driving don't do it. For track and weekend use its gold.

these guys are right on. all the multiple disk clutches I have tried or used were for track cars. they are meant to grab and hold withstanding high torque loads. on a car used for the street it is hard not to look like a jerk, both literally and figuratively.
maybe someone makes one for barstool racing with a soft spring and it will slip

part of the problem is the material used on the disc.

twin plate tends to be metallic, and it's not the best for "drivability"

organic disc material is more streetable, but they don't hold up to heat as well and tend to slip once you get aggressive with them.

I'm working on developing something w/ Japan, it may take a bit of time but hopefully something can be put on the market. If you're familiar with the Blitz Active Clutch from before, it'll be similar.

I have an exedy twin disc for sale ;)

It's not bad, imo at least.. I upgraded the clutch fork to the velox billet fork and it makes it a LOT softer. I could daily this car with this clutch

Glad someone asked here.

I have driven two cars (well three) with multi-plate clutches. The first two roads cars were fine. 500whp Saab Viggen and an N/A NSX. I actually really liked how both felt. Neither was difficult to drive. Was really hoping to get the same feel in the FRS.

Edit: Good to note I didn't have to deal with any hills. That may change my opinion on DDing a twin disk

Shouldn't a multi-disk clutch be lighter than an equivalent single disk high torque clutch? I thought that and a smaller OD was the point of having multi-disks.

I'll let you know next month.

Then why aren't you? And how much?

Not sure what you mean. As a whole kit yes it is lighter than an OEM clutch. The "problem" is you can't just slip in the gears as a normal clutch. It fully engages the gear. There is no slipping or that time where your depress the clutch.
That's great for track/drag since you can just tap the clutch and shift. No grinding or bad stuff. Just a super quick engagement.

I got way with daily driving my mr2 for a few years but then again I got used to the clutch. But after a while it gets old. The best I can describe it is like this. Everytime you are standing still, stand on one leg. You can do it first no problem. But every time you drive you have to do that.

I don't daily it because it's loud.. I wake up at 4am everyday for work and don't feel like waking up all my neighbors who are mostly retirees. I also don't daily it because I have about 20k in body work done to the car and would rather not have an idiot hit me on the road. I would rather have the car damaged on the track than on the road.

Asking $1100 shipped for the clutch

By "lighter"" I meant the pedal pressure. Motorcycles have multi disc clutches that you engage by hand. Although they are most wet clutches there are a few bikes with dry clutches. Weird that you can't slip them since you can slip the clutches on bikes...

I regret going with my OS Twin disc clutch because it couldn't even hold more then 370whp/340TQ. I'm currently sending it in for inspection and we will see what they say, if it could hold the power i wouldn't regret it since I kind of expected the car to be less forgiving on a daily driver.
