With the solid front mount and nitrous street tires just go up in smoke but no wheel hop at all (fustrating babying it off the line). I used to get wheel hop like crazy before the mount. Once had it so bad I actually got a flat tire (but after spanking a Mustang GT conv by 4 car lengths. well worth it and he never new it). Front solid mount good for <wheelhop but >NVH (noise, vibration, harshness) noteably above 5000rpm.
