Ok, so I installed a F1 brand 6-puck clutch today. It seemed like it was some kind of semi-metallic material, bought it off one of the miata people here brand new. Anyways, I installed it with no problems and it worked great for about a week. After that it felt wierd upon engagement. When I try to slip it in lower RPMs such as 1000-1500 rpm, it feels like it makes the car lurch foward in a rythmic pattern. Like it grabs and doesn't grab and then grabs again and doesn't grab again. Not chattering, but a semi-grabbing. Before this happened, I was able to slip the clutch easily with no problems. Any Ideas what this is? Did I break it in wrong? (just drove really really easy for the past 1000 miles)

Thanks

 

it's a puck clutch... they dont "slip". your description sounds about right for how they work. it probably *wasn't* broken in when it felt like it was working properly...

it's probably sintered metallic but without seeing it, I can't say.

so if you let it out fast, does it just grab like a ****? spin tires? that's normal.

 

IT is normal. yes they are sintered.

 

Ahhhh, I see. This is my first experience with this type of clutch!! It does grab like a ****. Stock clutch felt so soft compared to this one. It just grabs and goes!!!

Thanks Guys.

 

you should be good for about 230 or so whp with that clutch before it starts to slip FWIW
