I had my m05v2 working well on the weekend. However, my Yeah Racing long span ark kit arrived yesterday, so I installed it. Hopefully the car still works well; I'd really hate to have ruined the cars handling.
The rear of the car is much wider than the front now. Also, the car is much softer now due to the change in leverage ratio. I ended up installing much stiffer Springs in the front and rear to compensate.
Will try it out tonight at practice.

Edit: everything fit together well.... I'm pretty happy with the kit, especially for $65. Biggest issue I've run into is bump steer.... the front toes in a bunch under compression. I raised the ball studs on the steering blocks 3.2mm which has helped a lot.
