It is functional especially if you add the Archetype end plates. But it’s very minimal DF that I don’t think would require much of anything up front (could be wrong). Look at AJ’s video and the chart on APR it seems as though the R spoiler and the GTC are similar at 100mph.What do you guys think abou the APR GTC-200 wing? It's getting popular on this car; see them quite a bit. How would that one factor in?
