Hi fellows, next month I'm going to participate in a "Top Speed 4.000" event. It is an airport runway with 5km long and we are supose to go a fast as we can.
I drive a 11' wrx 5 doors. Does anyone has some tips how to increase a little the Top Speed of a WRX - if possible without loosing warranty? Is it really limited to 220km/h (137mph)?
