Mod 4 quick change option
Attention Mod 4 Drivers:
We have asked Wissota to give the option to allow quick change rear ends in your class. The first step in the process was reaching out to all of you asking if you would like this, 98% responded yes. All of that info was sent to Wissota to get us to this point.
Wissota sent every registered Mod 4 driver this questionnaire to your email yesterday, (please check your spam folder) to see what everyone would like as an option (quick change or Ford 9"). Please make sure you fill this form out asap as this is very important you respond to this survey.
