RFT vs non-RFT

[gaijin]

I'm in the middle on swapping from OE RFT to non-RFT.

However, previous threads I've ran across on the forum addressed 19" and 18" wheels/tires.

I plan to stay with my OE 17". Previous experience was with my first Z4 (E85). I liked the difference in ride comfort and handling the Michelin's provided when I swapped from OE RFT to non-RFT Michelins. Fast forward to my current E89 and its design changes (weight, etc.). Planning on staying OE tire fitment (225 - fronts & 245 - rears).

Appreciate feedback's from owners with this tire/wheel fitment. It's my DD and top-down whip. Thanks.
