i had both intrax and eibachs on my previous car and would say that intrax out perform the eibachs, but the eibachs are a better quality ride. the reason is if you read up on them they are different type springs. intrax being a linear drop, eibachs being progressive, that means intrax are stiff all they time, eibachs stiffen up as they are pushed or compressed. so with all that being said, i would recommend them from past experiences if you want to go with a lower drop than what the eibachs give.
