God man....... you really are the BLING KING! Not that there is anything wrong with it....... just not my cup of tea.
Anyhooo.......
If you are wanting to get better braking...... I suggest just get a good and I mean REALLY GOOD set of brake pads, ie. budget around $400-500 just for the fronts..... they will do wonders..... just changing the disk to a slotted item in my opinion will not increase performance drastically.
