I have started working with M Sport UK on my build so as I learn more about what they do I will share that. I figure that it may be pretty useless information though, as the goal is to convert the car to AWD which will completely change the dynamics of the car. That being said they do offer parts for their R2 spec car which is still FWD. and I don't think there is anyone in the business better at making a Fiesta go fast on a real road than M Sport.
