Tough question honestly. Most people will default to Zebulon because their front aero is designed to match their rear wing, and the GT250 should be in a similar ballpark aerodynamically – maybe a bit lower, but not wildly different.

If you don’t want to jump straight into a full, aggressive splitter setup, I’d look at GT4 canards or AJ Hartmann canards first. They add meaningful front balance without forcing you into a huge splitter right away.

If you decide to build your own splitter, starting around 4 inches of extension is a solid baseline. Then just test and tune from there to see how the car responds.
