EK4 and ITR booster and MC

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

you should to get a better pedal feel. but u can still run the itr calipers without the itr booster and mc

don't need to upgrade it will work fine still.
I had it this way for quite a while until my master cylinder started leaking, then i got an ITR booster and MBC.
It does make abit more difference, don't need to push as hard to brake.

Thanks guys,
so even for track purposes its ok? assuming decent pads and brake fluid :thumbsup:

everyone said it works.

being ok or not is up to you.
