I had just Esseesse Koni kit fitted and before that I was already aware with Koni's knocking issue and bolts solution to this knocking problem.
Finding typical M10x1.25x65 / 10,9 class and M12x1.25x95 / 8,8 class bolts is easy. However all of them have the part which is between bolt's head and their thread too thin which leads later to Koni knocking. This was 9 mm diameter in case of M10x1.25x65 bolt and 11 mm diameter in case of M12x1.25x95 and should be 10 mm and 12 mm diameter accordingly.
As I failed in proper bolts searching, in the end I had to have them custom made. M10x1.25x65 / 10,9 class bolts were made with 10 mm diameter and M12x1.25x95 / 8,8 class bolts were made with 12 mm diameter. Total cost was about 50 € with postage. Bolts are made of tempered steel and additionally galvanized. I reckon that they are better quality than OE one.
Before Koni fitting (out of curiosity) I put both custom made and OE bolts through shock's joints. With custom made there was almost no movement at all, as with OE one there was significant up and down movement. This 1 mm in diameter makes a difference![]()
Hi Gregi, excellent, please can you tell us the supplier details? Thanks.
