KYB's are better than oem, and certainly better than anything that Monroe makes.
I used KYB's on a car I used to autocross race and they were awesome, not that I am gonna autocross the Pathy.
I think KYB shocks are about the best "bang for the buck" as far as aftermarket shocks/ struts go.
The other great thing is KYB gives us at least one more option. A/M shocks/ struts have been pretty limited for the R51 so far.
