price and discount always welcome to me!

some items need better description. for instance, project mu rotors for a Mazda RX-7 (pt# PCRDZF3001) , am I paying for a single rotor or a pair when i purchase it? and uhh.. when i bought front shocks, i got a pair that was one model (white) FR and a pair that was black FL (front sides).... sell shocks by pairs, front pair, rear pair.... also, amke feedback relevant to the parts ordering, not just generalized to make yall sound good, which you are.

Quick and easy
