My TRD Sport rides like a chuck wagon and is jarring on even the slightest bumpy roads. Very disappointing ride. I plan on 18" wheels and C load rated tires. There has to be somebody that is looking at suspension parts on this issue.
There was someone on this forum that installed 275/60/20 with no modifications. I'm thinking about the same or going with 18" wheels and the 265/65/18. I'm also going to install a 1" leveling kit.
