I thought the 24mm might be a tad bit overkill buts its just perfect. Didn't take too long to install and has held up very well after the months I've had it. With the 24mm, the rear end of the car feels like its on rails. Only downside is sometimes you will have to spray some silicone spray on the end links to prevent creaking, but only had the creaking when loaded up with my milwaukee Packout and tool bags. The silicone spray fixes that even with an extra 250 lbs over the rear axle and only sprayed it once over 6000 kms. Overall great, tight in corners and suitable for the highway.
