i guess that really depends, some people have vibrations some doesn't.
I have 5mm spacer in the front, and no vibration at all..

 

Oh yeah, the ZHP has huge differences from the ZSP (Sport Package), performance wise, interior, and styling. Most notable in driving is the M suspension, the huge wheels, the sound of the exhaust, the short-shifter gear, and even little things like the thick steering. Plus, it's limited to 155MPH, and I've been with it at 149MPH and it felt extremely stable, the engine was working overtime, but t'was stable. It's much faster than my Benz obviously, but I love the Benz too.

But as for the acceleration figures, I think it's more like 5.9, 0-60MPH as per BMW, 5.6 is more like M3 timing.

Okay, I think I get this offset stuff, well - I'm just gonna stop asking.
