ae86.
with jdm rotors, caliper and pads.
cheaper than most stuff
and if you can afford the jdm rotors etc just have the adm ones in there for now.
think the rotors are bit thicker along with the pads on them over the ke70 ones.
me and garnett put mine in last night.
we f@$ked up a few things with the strut tops going on the stut and what not but it was fairly easy.
you can pick up ae86 struts fairly cheap, plus finding "performance" spring and shock combo is fairly easy. over other struts.
also, if you feel like spending big on brakes FC rx7 brakes can be made to fit with caliper mounting bracket or something like that, few guys have done that and would be almost certain to help you out with it.
5k should be able to pull up with standard brakes anyway.
and the geometry wont be put out.
hope that was off assistance man.
