Demitri, we used 2 pucks per side on Brandon's car. It was plenty, and left the bottom of the oil pan ~.5" higher than the subframe. It was a bit of a pain in the ass to get the bolts to go in that way, but it was tall enough no doubt.

The guy who did the actual write up for the mounts, used 2.5 mounts per side but he was running a CA18 and said that it almost hit the hood that way.

stock motor mounts are like 2.75-3" tall
