I was just browsing the UUC site and came across their new shift selector rod, which they call a DSSR. It sure looks cool compared to the stock rod.
The idea is to
address the wear at the transmission pivot end by spreading the shear forces over the faces of the rod. It also helps remove free play from the joints generally.
Here's a stock, worn joint.
The site doesn't say whether you get a new bushing for the transmission selector or not, or whether that's even replaceable. So I suppose this means that if the bushing is already worn, you may be out of luck. However, it seems like good preventative maintenance if your bushing is in good shape.
At present, there isn't an application for e39 M5s, or for guys like me who have the older EVO2 shifter. Any thoughts on whether or not this is or is not a good idea assuming one comes available? I remember what a PITA it was to replace my original selector rod and am not looking forward to doing this again, but it sure seems tempting (once/if the part becomes available).
For comparison, here's a Rogue WSR next to a factory rod.
