24 MM rear
I have only been driving with this bar for less than a month with the bar set in the center/ medium position. First impressions were very positive. The car seemed to handle more responsive in the rear, however, the improved handling only re-enforced the need for a better front swaybar. When taking corners the rear seemed to push the front end to lean more drasticlally. This did cause oversteer however it seemed to force tire lift out of the rear end on dynamic road transitions.
I had 2 1/4" wheel gap in the front and close to 3" in the back. With the sportline springs and pro-damper struts/shocks, I am now riding about 1/2" in the front and back. I do have a hard time with speed bumps mostly when the family is with me so I try to avoid them at all costs. I love the stance now glad my floor jack is a low profile! Note the pro-damper/spring set (4.10135.780) includes new bump stops so no need to purchase them separately.
Instructions are really poor!
I'm enjoying being able to adjust my ride. For my eclipse, they dont have the dial. You just have to pop the hood and they adjust where the end pops out from the mounting bracket. Seriously though, no words on the instructions, only tiny pictures that sort of tell you what to do providing you can decipher their hieroglyphics.Other than that keep your mounting hardware from the old shocks. The boot bumper from KYB fits into the boot, which for my car made the metal cup unnecessary, use washer
