bmw_tonci 0 Report post Posted January 18, 2012 Hi guys, I have a 1995 e36 328i, which has had an issue with shudders or shimmying at high speeds (i.e. 80-100kph) I have just had the rear top shock mounts replaced and this has drastically improved the shimmy at motorway speeds however it still shudders heavily while braking at those speeds. The mechanics have suggested having my rotors machined to fix this issue. Is this likely to be the only cause of the issue, or could other items be involved? Is it worth having the rotors machined, or just replacing the rotors themselves? What are the likely costs of both options? Thank you for any information you can offer! Cheers, Tonci Quote Share this post Link to post Share on other sites
*Glenn* 854 Report post Posted January 18, 2012 Shimmy at speed without braking can be tyres, suspension components or wheels ( hubcentric issues) Under braking the issues can be CAB bushes, rotors, calliper slides, hubcentric brake component issues combined with a combination of the whole lot. Machining the rotors will not resolve issues of shimmy that occur without braking. Quote Share this post Link to post Share on other sites

Complete set of OEM rotors and pads is less than $1k. The quality is better than similarly priced aftermarket stuff too. Quote Share this post Link to post Share on other sites
