I think I might be the only one with all 3 race mounts
Sorry Matt but I think I beat you to it... I had all 3 solid race spec aluminium mounts installed by Mark at VWR March 2009
As for the ride, its true that it really does increase the noise level and you can feel the vibration as you move off. It amplifies all the sounds from the engine bay and because I have an EVOMS CAI, it sounds like I am sitting next to Darth Vader at times
The transformation it gives to the handling and movement of the car is nothing short of astounding. No more wheel hop, the car just moves forward when you put your foot down with no lurching whether from standstill or driving on the motorway and turn the steering wheel left and right and you can see that the response had improved signficantly. I also have a non-resonated Milltek and that can get boomy at motorway speeds so I may change back to the resonated pipe but apart from that I am happy with it.
P.S. My wife has driven the car with our 1 year old and a 5 year old children in the car on long distance journeys - Ipswich to Birmingham - and around town and they are fine with it so stop being a wimp and get them
