I went with the Rebel engine mounts, definitely firmer then stock but not annoying. If your street driving is only 30% Im sure these won't be to firm.

*You'll need four 5mm longer mounting bolts as the mount's body is thicker then stock. The two stock big engine mount bolts are fine though. Probably obvious, but make sure to retorque the big bolts after your first few drives.
