It's no secret that S13 coilovers will bolt on to an S14 by only drilling out the front lower holes 1/16". Every bolt lines us except the ones that you have to drill out. It has been done before. What EVERYONE is trying to tell you is that the rear assemblies are too short by about 3-4". This makes the maximum height you can achieve in the rear somewhere around dumped. In fact, when the very first ever sets of Megan S14 coilovers were shipped out, they mistakenly packaged S13 rears and sent them out. Dozens of people were pissed because NO ONE could run like that. Your only saving grace will be if your rears have a retarded amount of adjustment. YMMV.
