Primary wishes: 1) greater stability with high speed lane changes, 2) whipping that thing around a traffic circle like it's formula 1 pushing through a chicane while barely slowing down. I'm exaggerating with #2, but I do like to push through the waggles. I'm impressed with its handling as it is, both on the highway and through the curves. Just want to tighten it up, reduce body roll, increase stability - and given my driving style make it a safer vehicle. When I choose to drive aggressively I probably don't push beyond 85% - where I live, though, opportunities to drive aggressively are limited.
