I have installed a SSK by UUC and it is really great: very short throw, but it is bit too notchy for me so went for DSSR as well (still by UUC). I didn't have any luck in installing the UUC DSSR in my 335is yet. The DSSR for the E90-335i model doesn't clear the drive shaft of the 335is, so decided to send the stock shift rod to Rob at UUC and have him duplicate the same curvature of the stock shift rod. See pictures at:

Now, the custom modified UUC DSSR clears the shaft but the car will not go in gear as it touches the bracket for few mm, as my tech explained me. Tech used to be the foreman at BMW dealer and knows E90 inside out so I trust him.
If any owner of 335is has successfully installed a SSK and a
DSSR and is willing to provide details/help , I would be really grateful.
Thanks
