No you can't really deal with this problem, I would get that fixed. This will cause your parts to move more then required, therefore putting stress on parts and eventually breaking. You will end up in a really bad situation, I've been dealing with my sunroof for 6 weeks and $300 in parts and it still doesn't tilt. I finally found a place that will work on it...
You said it was an aftermarket(so it's not BMW), maybe your pieces aren't plastic.... Good luck man.
