very usefull :D

I've put together an Excel file which shows the effect of fitting various sized diff and gearboxes to the supra, it also contains a graphical chart showing the effect different tyre & wheel sizes and offsets effect both fitment to the hub and the effect on speed/acceleration. There are two main sheets on the file, Wheel size fitment and gear ratio calculator.

 

Before it goes to the tech reference section, can some of you please review it and see if there are any errors or faults?

 

Also, any suggestions for enhancement are welcome :)

 

It took a silly amount of time to research the data and put this together, so hope it's going to be useful to someone :D

 

Edit - updated with "final" version..

Thanks for the reminder Guigsy, need to update this to the last and hopefully final version

 

Its the normal code isnt it :-

 

Crown Wheel Size: A (8'' - 203mm), B (8.7'' - 221mm)

Differential Ratio: 01 (4.083:1), 02 (3.769:1), 03 (3.267:1)

Differential Type: A (Standard open differential), B (Torsen LSD)

 

Wes, you (and Digsy) were right all along, the above codes are correct :) I'll try and sort out the last version this week and upload to the tech section. Sorry for the confusion, my mistake entirely.
