I have one of these on mine now, but only until i can afford to get the full set from INA.
Should be 20 lb/ft
Which means you're about 25%+ (5-6 lb/ft) light Head-Up, which would definitely make a difference I would imagine.
The INA is the full mount not just bushes, its about 100 quid.
If you are getting the other 2 mounts as well as i plan too add just over a 100 again
