Hi everyone,
I've serached and only really could find stuff from 2007 or older and not much stuff in case of EK4.
just wanted to make sure nothing has changed since then.

if i upgrade to ITR calipers at the front, do i need to upgrade my EK4 booster and MC 15/16th's to the 1" ITR booster and MC?
For street car but i'm now actively trying to participate in track parctice days and hill climbs.

everything i have read so far is yes or no.

Thanks
