I have the 034 street density and they are great! Took a little time to break them in, but once they did they are exactly what i was looking for. Don't rattle your brains out, but definitely stiffen up the drivetrain.

 

The only time I ever get a chatter is if i rev it with out the clutch in, it will chatter on the rpm drop. And my flywheel is 9lb billet aluminum.

 

What clutch are you runnin again? Is it tough to drive in traffic?

 

WOW 9 pounds and it doesn't chatter? Did it chatter when it was new?

 

Now a werk of art custom dual diagram with a CM sprung hub 6 puck. But I've had this flywheel with a few other clutches.

 

Definitely glad you put this up. This is the exact clutch I'm planning on getting, already have a SMFW in so sounds like it should be pretty easy to adapt.

Also idk why anyone wouldnt get the 240mm, definitely worth a little extra for the clamping power.

 

If you wanna go with this clutch package I really think you'll like it. The only reason I can think of that you WOULDN'T want the 240mm upgrade is for a racing situation. The larger diameter flywheel/clutch would take longer to shift in a drag racing situation but for a street setup it's very good.
