[HELP] Any differences of the suspension on E46 sedan & coupe??

[aron325i]

sup all

I'm driving 02 E46 325i with sport package and one of my buddy bought the 02 E46 325ci with sport package, so I did the testdrive on his car and I found the little bit of difference between two cars.

Eventhough both car had SAME sport package suspensions, I found that my friend's car(325ci sport package) has stiffer and more stable suspensions than my car's, and it has lesser ROLLING during cornering. I don't really know why.. cuz I heard that sedan is lighter than coupe and it has SAME sport package suspensions.

Secondly, 325ci had harder and heavier steering wheel feeling than mine, and after testdriving 325ci, I got on to my car to compare it, and it actually has lighter and softer grip than 325ci. I'm kinda worrying about it, cuz I like the heavier and harder one better and it felt big difference to me.

Only the differences that my car and his car are remain of tire treads(mine's like DEAD and he got new one ), and miliege(mine=50000km, his=70000km).

Does anyone has any ideas of these differences??(Like.. do they use different shocks or springs on their sport package?)
