Never tried Sensa trac but had GR2 on an old lancer shelby I had and they sucked. They were just really soft. Have the gas a just KYB on the back of my 89 CSX and those seem to work pretty good. CSX-T worked great when I put an nos set of Formola GPs on it. Took them off to go to the Konis a few years ago. Wierd thing is the GP were "almost" as good as the konis. Just picked up a set of Gaberial Ultra for my 89 CSX. I'll pass about how they work. Also I am pretty sure the struts and shocks you get at the dealer are all the base ones now seeing as all part numbers have changed over to a universal number.
