Thanks for the pic OCD. I still think the Alfa wheels look to be the right diameter. Look at the pic pushrod put up and see how the size difference is almost the same as OCD's pic. If I could find tires that were a little taller, and fit the alfas wheels, I think they would be perfect for the gravel setup Lancia 037. I'll need to lower the body in respect of the chassis, then raise the chassis to gain ground clearence and I think it would work.
I will say this, I know you guys have a lot more experiance with Tamiya RC cars then I do, so I should probably take you word for it. I just really dislike those tall wheels.
