I've recently got the Steeda diff brace and I also have a spec 2 plus clutch.
When I'm coming out of 1st gear (at the end of 1st gear - there's a chatter
noise). Has this happened to anyone. What could that be? It only does it
in low rpms. It does not do it in any other gears. Just in 1st.

depending on the year of your car..

older T-45 transmissions do that sometimes with age.

Try flushing.

It will chatter if its a new clutch, the diff brace wont make it chatter.

it will chatter is the flywheel is warped
