Frequently Asked Questions - BMW M coupe Suspension System
The current Dinan Strut Bar does not fit the '99 coupes so how does one modify the bar to fit?
On the passenger side suspension strut dome is a special nut that BMW installed for jump starting the car. The nut is now mounted a little differently than the '98s and the Dinan strut bar comes in contact with it preventing the install of their bar. One can remove a little material (with a Dremel tool, etc.) off the Dinan bar to get the bar to fit around the nut.
