Today I finally received the gd600 tranny! and also the m-chassis tires I bought. Still waiting for the wheels though.
Here is a size comparison with tamiya touring car tires. The m tires are tamiya too, the medium size is 60D (60mm) and the small one is the 55mm model.
I think the medium size (60mm) will be perfect for the escort! By the way the disc in this picture is from the crappy chinese kit, but are almost same size as the one Prestonlal will be sending me! (I am buyin some of his leftover parts from his disc brakes and Venom 1/8th scale bike brakes) :banana:
