According to Eric Stoddard, the proto design models showed significant lift in wind tunnel tests. The spoiler was required in this car if it was to exceed 120 MPH.

Mine does, so I am sure Mr. Stoddard is likely right.

I have driven mine without the spoiler activated and at about ninety the rear end gets soft. At 115 MPH it gets loose.

However, at 160 MPH it holds like glue with the spoiler deployed.

Whether one believes me or not, Mr Stoddard does have credentials.
