Hey i was wondering if there is any way of getting my car to go faster and accelerate faster .

Are you thinking about modifications??? If I were you and wanted a faster car, I would trade it in for another vehicle.... Forget making changes.... How about a. Subaru WRX STI???

Have you thought about bigger turbos or better air intake/exhaust or any thing you won't need like spare tire jake things of that sort take them out for weight reduction.

Hitch it up to a Viper.

Look at iPd... PLENTY of upgrades available for an S60. You could also look into a Polestar tune. Easy way to get more power, and it will be loads of fun to drive!
