p1sc is a 6 rib? and d1sc is the 8 rib?

[Collin]

I am confused....

so the P1SC is a 6 rib and the 8 rib option is 1200$?

and the D1SC comes with the 8 rib?:confused:

p1sc and d1sc are both 6 rib unless you opt for the 8 rib option.

The eight rib is only about $100.00 more, but you do have to buy the new harmonic balancer/pulley combo. :)
