Sorta... Until yesterday, I hadn't driven a FoST. I drove a mildly tuned FoST and here are a few thoughts of my back-to-back drives. The FoST has a ton of power! I knew it would have torque steer, but frankly it surprised me just how much. I think you'd get used to it, but wow. This is considered an evolution of the MS3 chassis, and benefits from some changes that make it better. I just figured it would be a lot better, maybe it is? It sounds great with a Mountune exhaust! I hope our car comes out sounding that good too. It feels huge! I thought of my car as 7/8ths a FoST, but that doesn't feel quite right, now. The FiST is a lot stiffer! Ford really was more aggressive here. While I can be tricked to believe I'm seeing a FiST in a quick glance, I'd never think I was driving one from behind the wheel of a FoST. It's nice to have choices, but I'm happy I have a FiST.
