Lower engine mount

[Niall]

Afternoon all,
Ive currently got a yellow Powerflex bottom mount which was spot on and a nice compromise on the standard engine however since fitting the charged engine, its not really standing up to the job i assume because of the extra power. Im looking for something a bit stiffer but don't want to go silly as i don't like the whole cabin vibrating lol.
Are the diesel powerflex mounts any stiffer than the petrol ones? And if thats a no go, I've heard of some people fitting a standard mount 90 degrees to the standard position. Again, any good?

Thanks all
