Not seen a hawk sti for sale in a while now .
UK might be your best bet .
But if I were u I'd consider a widetrack blob . Know you have a blob all ready but cheaper tax and stronger engine are 2 major factors to consider . If Deffo on a hawk drive her hard in boost and slow down to normal driving . If the heads are lifting or hg is fucked the engine temp will start to rise above normal considerably . It's not a major problem to fix but not nice .
