Hiya mate
Brakes are still not perfect, but in fairness they may need a little more time to bed in.
Ned is by far one of the most clued up and nicest grease monkeys

I've ever met...top bloke
He had a look at my front brakes, gave them a clean and put the pads back on...they are now considerably better than they were before.
When he'd finished cleaning the crap of my brakes that the fecking butcher that had previously fitted my discs and pads couldn't be bothered to clean off we went for a spin in his 2.5 V6 which is essentially a bog standard car with the exception of a Q2 diff and some new shocks etc.....
****** 
me the Q2 makes a HUGE difference to the car.....
If you can afford the upgrade
DO IT !!!! I'm sure the upgrade will transform any performance grip / stabilization problems the GTA's suffer from.
By the way you lucky bugger I always wanted a Blue GTA when I was looking and could never find one...so I settled on plain old red
