Wow, I had a few guesses in my mind but this was not one of them. Guess I don't pay close enough attention.
Great to see someone trying this, it's been long enough coming. Though honestly this project is above 99% of people here, either in scope or cost. The details should be interesting.
To comment on what I see, what materials are you using? The subframe looks good but all of the suspension links look awfully small. Maybe I'm just stuck in the world of 4x4s, but I would expect larger. Especially in rally when it will be abused. Details?
