did philcom use to stock these. how much do they retail anyway. is there a noticable diff having them. thinking of getting one, for the handling and thebling factor but just wanted to know if they are worth it

I have one, and it makes a pretty big difference when cornering and virtually eliminated torque steer under hard acceleration. My suspension is stock apart from that.
Yes Phillcom still stocks them. I cant remember what I paid for it, but I think from memory it was around $170-$200. But well worth it.
I need to get the rear and front sway bars now.
