I have just fitted a set of Density 'Street' version mounts to my Mk1 Octy last friday.
I did have a powerflex bush fitted in my dogbone mount as well.
The car does feel a lot better now,accelleration is smoother and no lift off from the front end.It feels more stable turning in now and i haven't got any nasty vibrations on start up.
I managed to get mine in a group buy last year when the dollar was a lot better,something like £176 including delivery and VAT.
I don't think i would buy them at the current rate as it would cost nearer £280 once you facture in VAT etc.
The group buy last year was on SCN and was though INA.
