I've been looking on the G-Force website at different packages you can get to up the power but im a tad lost, well i think they are.

It says the package is for a WRX but it says it raises the power from 205 hp to 275 hp. Surley they must be on about the UK cars ??

Also whats the difference between a WRX CS and a WRX RT ?/

Heres the link
