My 2015 still isn't turning exactly how I'd like, which is more like my F4i. Before you say "but the f4i is a 600!" remember they weigh 1lb different fully fueled because the F4i is literally an indestructible tank. Anywho, I went ahead of put a 190/55 on the rear to raise it slightly and really liked the improvement. Can't raise the rear anyway else that I know of without a new shock, so that leaves lowering the front. My F4i has a healthy front end lowering, any issues with it on the 1k? Or is there another way to raise the rear that I'm not aware of?
