2 questions:
1) will the M performance brakes perform any better than the M sport brakes? I assume less fade b/c cross drilled/slotted, but what about stopping distances or significant weight reduction?
2) If an M performance power pack is coming soon for the n55, then I'm confused about the supposed ///M335i. I mean what's the purpose of these little dealer-installed tunes when there's bigger factory fish on the horizon (///M335i or ///M3)?
