One thing to note (and not cause I own one). The MS3 is VERY difficult to mod safely. The GTI is the opposite. Have known 2 people that ditched their MS3's, one after a broken turbo from a slight boost increase. My GTI with a stg1 APR is like ...fast. Stg 3 would really necessitate wider tires and an LSD IMO. I can spin thru 1st, 2nd and chirp in 3rd with Michelin Pilot Sports.
I hope the Ford will hold up well to mods since it looks to be a great car!
