I got the THS mounts fitted today, all 3 including the dogbone. I see what Willie means about the front bush of the INA dogbone being soft, it is! I fitted the Superpro void fill bush into the THS dogbone mount and now it is significantly stiffer, the rubber bush was stiffer than the INA mount anyway. Will give driving impressions tomorrow.
Sadly I have found 3 holes with stripped threads on my car, parts were previously fitted by Star, 3 loose bolts around the engine which will not tighten, so I am going to have to revisit these and fix them with helicoils or something.
