I did this as a way to look at RC chassis vs. real car chassis. For the Mini Z and the Tamiya I used millimeters, divide the wheelbase into the track width for the aspect ratio number.

To keep this simple, I figured these with 0 offset wheels for a standard benchmark figure. Also the track width is based on the front width.

I learned this idea from scaling model rockets from one tube size to another.

In a way think if you can scan a car into a computer and resize it to fit the Mini Z chassis.

I used the Dodge Challanger in Car and Driver as an example, also used a Tamiya M chassis as a comparo to the Mini Z chassis.


MR01-MR015 with 0 offset wheels.
86>65=1.3230769
90>65=1.3846153
94>65=1.4461538
98>65=1.5076923
102>65=1.5692307
106>65=1.6307692

MR02 with 0 offset wheels.
86>70=1.2285714
90>70=1.2857142
94>70=1.3428571
98>70=1.4
102>70=1.4571428
106>70=1.5142857

Tamiya M-03-04
210>165=1.2727272
225>165=1.3636363
240>165=1.4545454

Car and Driver source for the Dodge Challanger SRT8
116inch>75inch=1.5466666
It should be noted that the wheelbase is shorter than the 300c chassis.

Feel free to add your own ideas and figures. My calculator only has eight digits on it's display. It is funny that all the Tamiya figures turned out to be repeating numbers.
