I'd say focus RS, more pricey but comes with a quaiffe diff and is oober strong. It's easy to mount, Gear cables are easily fitted, loads of clutch choice. The tricky bits are hydrolic clutch pedal and electronic speedo. I've used an RS2K box but its a hore to mount in comparison, clutch choice is poor and gear selectors are not much fun either! All the mtx's have good points and bad.
