nope dont agree with ppl when they say not to use them in most cases your bike will slide them if it digs in its just unlucky, its no different from rd to track as ive proven already, and hopefully ill never have the case of my bike flipping over, i tell you one the best things i found was race rearsets espec at croft when i low sided racing, the solid peg helped lift the bike up and slid on it and the r&g bobbin, the damage only the peg and rear brake lever was damaged £60 sorted that out ready for next race

so def buy some mate along with casing protectors
