I ordered GT250 but they sent me a GTC300... both are 61''. Should I keep it or change it to GT250?

all boils down to what you think. i have the 250. others have the 300. others have voltex. depends on who you ask

Bullwings

change to GT250. The GTC300 is a 3D wing, and while it generates a lot of downforce, it also produces quite a bit of drag. The GT250 is a superior wing when you look at both downforce AND drag.

thanks. Is 67'' necessary or 61'' good enough? 67'' seems too much for an NA S2k?

maomaolong

do you have the 67'' or 61"?

Orleansjunky

67"

maomaolong

Orleans, your car is NA? what kind of front aero do you have?

Orleansjunky

just that and front splitter. BUT i"m at stock height so splitter doesn't do much. yes NA. local track has an "s" section avg 90's in turns. when they run it as the back straight the turn before is flat out and at 100+ and was really scary without a wing.

maomaolong

so you suggest the 67" instead of 61"?

The wider wing should let you run less angle for a given downforce. That should be a better L/D ratio and less drag.
