Spit6 / CGT6 Project

  What about the braking systems?

czone.gif (3321 bytes) Please forgive us....  we're almost ready,
    but this area is still under construction.
....data still being collected and updated....

 

         Brake cylinder sizes varied across models. Looking through parts catalogs and other tech. literature, I've been able to put together a list  as follows:

The GT6 had larger disk rotors and calipers.
Solution
: Use the entire front suspension from from the GT6
