Can someone tell me for sure if all B16a stock flywheels use 9 screws to hold the clutch pressure plate or are there also 6 hole flywheels/pressure plates for this engine?

Also, what's the scoop on lighten flywheels? Good or bad mod?

Thanks!
Raul

 

There are 9 bolts and the lighten flywheel is a good thing to do i just put a zex 10lb flywheel and act clutch and i like it alot
