2 shims will reduce the amount of fluid that leaks out. Can't say all fluid leakage is eliminated. If the container is overfilled, fluid will leak out.

You can run the reservoir a little lower because of the increased recirc flow through the regulator which can help lower or eliminate leakage. I run my E46 so the fluid just touches the dipstick. Typically, no fluid leaks out. If I fill it higher then there will be some seepage.
