T think it's only worthy if your v8 STi is MY05 GDBE because it shares the same rear fender as the v9.
If yours is MY02-MY04 and you only convert the front to v9, it looks weird.
Since you just bought it, I suggest you spend the money to improve the handling and power. Once you like what you're driving, the looks really comes second.
