OTL Porsche GT4 Cup


Discord: https://otlracing.com/discord

The Porsche GT4 Cup is an all new OTL single make series featuring two sprint races per round. The Porsche Cayman GT4 is probably the most tame of the Porsches in ACC so the series will suit drivers of all abilities while producing intense close racing being equal cars.

Please note that this league is on Monday evenings.

If you haven't taken part in a previous OTL league you must successfully complete an evaluation race. Two evaluation races normally run two weeks prior to the season start. 

We hope to see new people racing with us, as well as many regulars. To get involved please join the OTL discord at https://otlracing.com/discord. The signups are limited to 40 drivers. Another split may open if there is interest.
