Now I'm at 86% and I wanted to finish all missing things, but the Stock Car races don't show up anymore. On my second playthrough, I only played the main missions (to invest all my millions in Lester's assassination stock market speculation afterwards to gain billions), so I skipped most Strangers & Freaks missions and only did a few random events (especially Simeon Yetarian & the Altruists, since they are limited to certain conditions). On my first playthrough, I finished all stock car races immediately after I got the email from Ron.
