Boxster Wheel Offsets

[Hilux2400]

I have some Cup 3 Mille Miglia wheels to sell and a person with a Boxster wants to buy them, but is unsure if they will fit his car. The wheels have the following dimensions:

10J X 18 x ET47
8.5J X 18 X ET50

I think the fronts will be OK, but the back wheels might stick out a bit.

What are the recommended ET values for 10J's on the back of a Boxster?

ET on a 10" Boxster rim is 42.

Based on that a 5mm spacer would be required when using an ET47 wheel.
