I know it reduce roll, but by how much? I've recently discovered my car has always had a broken endlink. My car has quite a bit of roll even at 10mph corners, feels like it'll bottom out on one side. If I was to upgrade to the cl type s rear sway, and fix the front endlink, just how big of an improvement are we talking about here? Also my ex has the 27.2mm hollow fsb, would it be worth upgrading to the solid bar?
