It felt isolated...as though I were driving on perfectly smooth roads (even when I wasn't). My E46 with urethane LCA bushings will transmit jolts and impacts right to your hands.
Most people don't like that, but I do. Feels more interactive. It could be that I've gotten too used to the urethane bushings, but I still remember my buddy's E36 doing something similar, even with the stock bushings.
E90 with or without ZSP?
The e90 without ZSP would feel that way.
The 325 w/ZSP with the Bridgestone RFT's are really bad over bumps and road imperfections. I could only imagine the 18 RFTs to be worse.
On the other hand, the RFT really shines on flat and perfectly smooth roads.
