Hey, in my opinion, i would go with GC over the Eibachs. I would even go with H&R's before Eibachs. From what i have seen the Eibachs make the back look heavy. I know gr8ride has 18's or 19's on his SVT with the GC, so wait for him to reply, or drop him a pm. I dont really know if they will mess anything up with stock struts tho...
