Im just doing a very minor refresh on my Nitron's, as when i removed one damper from the car, i noticed that the O ring had pinched out of the side when a top had had been put in. Iv contacted Nitron, and they told me the spec of O ring is 19mm x 3mm. Now, the O rings iv taken out, seem to be 19mm x 2mm. Iv rung Nitron to makesure, and they have confirmed its is 3mm, not 2mm. Looking at the kit that ES sell, they look like 3mm O rings, but no spec is given. http://elise-shop.com/wishbone-bearing-maintenance-kit-p-502712.html
Was the spec changed maybe, and mine are the old spec?
