I had the Woodhouse motor mounts and trans mount installed a few months ago-Ab did the work. I really like the mod. Just a slight amount of vibration in the steering wheel at idle - when you hit the pedal, especially at wot, the Viper seems to be a lot more connected. I wish I had this mod installed when I first got the Viper.
Both Woodhouse motor mounts come with a small protruding nub. The factory mount on my Viper does not have the nub on the passenger side in fact it looks like the nub was filed off. Ab ,in order to get the mount installed, had to file off the nub. He said he tried everything to get the passenger side installed with the nub, but no luck.(see the pics on the motor mount install thread that I mentioned in my post above)
Some Viper owners have been able to get the mount installed without filing, but a few said it made it more difficult to install.
I am going to put it this way-I am very happy that I did not try to install the mounts. Thank you Adam.
