as an update on the whiteline droplinks i honestly say i cant endorse them ive only had them on a few months and there knocking like mad already also they clunk and creak when turning on full lock one of them also fell off a few months ago when i was driving and when i investigated the thread insinde the arm had completly flatened so the bolt on the bottom eye had litteraly pulled out of the bar total waste of £115 in my opinion maybe there only suited to track conditions but dont get them for road use im now looking at the astra h droplinks theres a thread on here saying they fit onto the g and are made of metal so i think thats the way forward
