Love this car, love it, but hate the way the rear Lith/Ion batts load up the rear suspension. I'm thinking they left the stock parts of the Hybrid there, saving money. Seems squishy soft, bottoms out in road dips. A bit swervvy in hard fast cornering (on off ramp frwy) Thinking a replacement set of new gas KYBs, or Konis in the rear might do the trick? Or replace w/stiffer springs/struts? Second question: Best tires for the 18", five spoke rims ? : 1. Best (lowest) rolling resistance, 2. lightest weight (sprung) and 3. best value, performance, noise, grip, handling. I'm thinking a +2 wider, lower ratio tire may add cornering ability and more stiffness, def. lower rolling resistance, even with wider tread/track - better mpg! Michs, Goodyear, Kumho, Sumitomo ? Do 245/45/18s fit without mods, clearance, or does circumference change affect the mechs of the Energi? Does anyone have experience with this upgrade? Thanks, Q
