I'm loving mine so far!
Curious about your complete setup. What wheels/tires are you on? I am definitely not feeling any resemblance to M-Sport. Even on smooth roads, the car does not sway or rock over rolling humps. The car just feels glued to the road and follows every contour. I am once again in an M-Sport this week as dealer checks alignment on mine and car definitely sways and rocks more like a "comfortable" ride - even with the same ARBs. Kind of made me a bit nauseous cuz i'm not used to it any more.

It's bumpier than sport (not much... but it is), and WAY bumpier than stock.

All that matters not, however, 'cause it corners like it's on rails

Definitely be careful with passengers in the back seat. Especially if they are tall and have limited headroom. Already gave one of my passengers a bit of a headache over a speed bump at 1 mph.

I'm thinking the difference TreDirtyFive is suggesting might be from higher profile tires. I'm on 19" 403M setup.
