Which clutch mod to go with?

[5280 Busa]

I am trying to decide which clutch upgrade(s) to go with. I have read that Brocks clutch mod is good but also that Carpenter racings solutions are good as well. So the question is:

What do I need for street and track?

Both companies offer a clutch mod and both offer a similar looking cushion kit. Do I go with this:
