Regarding run flats, I'll need to see how the car feels with the wheels (and accompanying tires) I got. This is actually one of the reasons I wanted to wait for the LCI.
On my pre-LCI E85, after I went through the run flats I replaced them with a nice set of non-RFT Pirellis, which as we know, transformed the car. However, in my post-LCI E85, same size wheels/tires, car felt better than my previous one right off the bat WITH RFTs (bought both cars new, just FYI). Without making a hullabaloo about it, BMW def changed the suspension settings to accommodate the run flats better after the LCI. I ended up leaving them on my car for 5 years.
When my E89 comes, I'll see what the setup feels like and go from there  .
FWIW, I also have an E85 buddy who was in what would have been a VERY bad incident (18 wheeler drifted into him on a highway on-ramp), in his case, the run-flats ended up playing a crucial part in minimizing the resulting danger. |
In both of my previous E85's, I did the same thing (switched out for the Pirellis) rather quickly. However, after 4-5 months in the new is, I still haven't felt the need to get rid of the rft's. You're on to something about the suspension. I'll probably still switch them out, but I want to get an autocross or 2 on them before I do it.
