New Clutch

[2012Boss302]

I asked over on TMO Facebook about the difference between a Boss flywheel and a GT flywheel and got, as usual, excellent answers. Now I will ask here about brands. Originally I was thinking of an Exedy Mach 600. Now that it appears I need a flywheel as well, has anyone had any experience with the Mantic single disc clutch? I am staying N/A for the foreseeable future as I am not finished with doing track days any time soon. I don't feel the need for a trick multi disc clutch.

I replaced my stock clutch with an Exedy Hyper Single this year, very pleased with it. It is a racing clutch and acts like one, you do not slip that clutch but it makes shifts like they should have been all along. It comes with a lightened flywheel.

+1 on the Exedy Hyper Single. The only Mantic single disc I could see still has the steel cover assembly, and is priced pretty close to the Hyper Single, which has an aluminum CA and puck style disc. As @JDee mentioned, it’s a proven race clutch so the higher engagement point in clutch travel takes a bit of getting used to for street use, but doable.

Exedy Hyper Single is pretty much the gold standard

Yup have the exes hyper single and love it! Didn’t need a flywheel though just took it to get machined but either works great

Another vote for the Exedy Hyper Single! Installed mine over a year ago an it solved all of the lock out issues.

Kohr Motorsports calls the exedy hyper single their "Go to" clutch for road racing...that was good enough for me.

What are the downsides to it on the street? If I put a lightened flywheel in it, I have sense for what that will do with the lower inertia. But how does the Exedy feel for the weekend street cruise? Is it decent enough around town once you get used to how it takes up?

Now I haven't had a chance to run mine yet but the flywheel isn't really all that light.
I had an aluminum flywheel with an RXT double disc and that worked great but I'd bet the weight was about the same as the single with lightened steel flywheel. I had a chance to weigh them both as I was installing the Exedy this last Sunday.
I thought about it and decided "Who's gonna care besides me and whatever the difference is I can't change it anyway so why bother?" I just knew I'd regret that and here we are.

I drive mine with the exedy on the street all the time with no issues the pedal is a touch “stiffer” but really not bad.

This is good news. I have really bad knees and worried about this.
My RXT was super light on pedal pressure and I wondered about the pressure on the Exedy.
Thanks for putting my mind at ease.

Yea I didn’t think there was a huge increase when I changed it out. So you should be good!
