hi everyone. i need some help gathering information on some struts for my other car. i have already purchased springs with 300 front and 350 rear spring rates. im currently looking into the struts listed below but i need to know what type of driving the struts were meant for. i tried to find information on the struts below but i did not come up with very much information. if you have any information of the struts below please feel free to post.

e-spec kyb super strut
j-spec kyb new sr special strut
Gab super hp
koni red

it meant as an oem replacement? is it meant for sport springs or is it a race damper?

right now i dont think the koni red's are up to par with the spring rates i want to use so im leaning more towards the gabs for adjustability. does anyone know where i can order gabs in the states?

if externally adjustable koni sports are not available for my car, can a set be made to work with my car?

thanks
