Thant's very valuable information!!!

The higher the drag, the more resistance to movement. gf is grams force.

Regarding the other values, I think the higher in the front will give you more steering, the higher in the back will allow you to turn harder without loosing the back...

Anyway, not sure about the negative values, does that mean the body actually lift??

Negative numbers - lift!
Not all that unusual really... most cars create lift at speed. Think of the general horizontal profile. flat bottom, curved top and a higher angle of attack at the front than at the back!

Wish we had more of these tables for teh other shells out there!

Forgot all about this post! Thanks for the conversion. I figured it was lift and such, but never heard of gf before so it make more sense now. These are just from the TA05 guide book, but I wish they did this for more bodies, if only for more Tamiya bodies.

Makes sense though, the NSX is the best of the realistic shells.
