I've had the UUC SSK in my E46 for 40k miles and 3 years. Its held up very well, you do HAVE to properly torque the 6 bolt for the ERK mechanism. But I grind when I've got full throttle in first and then quickly shift to 2nd. I have to wait a quick moment before it will go in. Never had that issue with the OEM shifter with the same Royal Purple gearbox oil
I think that you may be right as far as the E46 is concerned. I used to have a similar problem with my E46 M3 when shifting from 1st to 2nd but I thought it was the clutch not engaging early enough. I used to have an aftermarket clutch and the biting point was very small.

I now have a E92 M3 with AA SSK and DSSR and do not have this issue at all. Infact, the shifting feels smoother than the stock shifter. The throw in the E92 SSK is not as short as the throw that was on my old E46 M3.
