But back on topic thought, given how much Al is in the Z4. Is the +400lb to +500lb compared to the Boxster really all down to the soft vs. hard top?

Apparently not... in below table soft-tops add, on average, 180lbs, compared to the fixed-roof versions of the same platforms. Hardtops add 330lbs.
So hard-tops add, on average, 150lbs more than soft-tops.
The previous Z4 and the current boxter/cayman platforms are "special" cases where the soft tops add no extra weight compared to the fixed-roof version.
So to try and guess the answer to your question, the Boxter vs Z4 weight difference may be explained by:
- 50% Soft-top vs hard-top. Adds on average 150lbs.
- 40% Turbo Engine vs NA Engine. The weight difference between a sDrive30i and a sDrive35i, both 6MT, is 209lbs.
- 10% Others: More compact drive-train due to center-engine layout. More/better use of Al due to lower cost price (leveraging VW group purchasing power). Others? Weight difference: Unknown.
