I have also just changed from original fitment Yokohama to Good Year efficient grips on my 2011 Plus 4. I certainly noticed the "softer" ride ( and less rattles etc) but am pleased with my choice. The old tyres were getting hard walls and the car now feels more like when it was new and is even a greater pleasure to drive. I went for Goodyear because of economy, wet grip and noise ratings being amongst the best (or so they say) I haven't hammered it into bends yet, but don't feel any less confident.
