You would only notice torque mounts through linkage. I didn't run any torque mounts on my B16A throughout the whole time i had it, just made gear changes a bit sloppy at higher rev's as engine was swinging. If anything, that would cause less vibration as less of the engine is touching the car. Same as if he had the opposite and had Hasport mounts with the harder rubber, it would shake like hell ha.
Rotors are gone? I had the same problem in my em1. one of the engine mounts were showing signs of wear (front support) i replaced Didn't fix...went on re balancing, new tyres, re machining the old rotors, new bendix pads even went to 6 different mechanics.
It was the rotor's, changed the front 2 and no problem at all. Try it cant hurt.
K i read the tread, it was a similar problem. The car would rattle shake like fudge effects heavily felt from the steering wheel when trashed or breaking from a high speed..coming off the m5.
