Spengler was announced as one of three drivers in the Studie line-up for 2023 last month, the Canadian joining team regular Seiji Ara and newcomer Masataka Yanagida at the wheel of the #7 BMW M4 GT3.
At the time of the announcement, it was unclear exactly how many races Spengler would contest, but it has now been confirmed he will appear in five rounds this year, with Yanagida stepping in for the remaining three.
