I built a Factory Five Roadster 15 years ago and I'm now looking for my next car project adventure. For decades, I've been intrigued with the idea of moving the engine/suspension of a front-wheel drive car to the back of a vehicle to create a mid-engine car. With the 818, Factory Five has shown the way; plus I own an '06 WRX so it seems like destiny. My plan, however, is to forgo the kit and use Miata parts for the front end to make a vehicle that's a bit more unique. This will give me tons of opportunity to try different things (my favorite part).

My first question is this. What is the minimum modification that I will need to make to the WRX front suspension so it will work for the rear suspension of my build? What attributes does the rear suspension have that the front suspension lacks? I don't have a good understanding of why Factory Five made the changes that they did but I would like to avoid unnecessary expense and work. Any advice would be appreciated.

Thanks
