Tokico Illumina gas struts are very good quality. i just installed some this past weekend. and since they are 5 way adjustable they keep my front tires from spinning. im pretty sure they will go good with the sportlines you have too. i wouldnt go with the KYB AGX's, dont get me wrong, they are good, but if you lower your car more than a half an inch or so the ride quality will suck. correct me if im wrong everyone, cause im not sure. Good luck man!
