*brakes
Project MU NS400's are my pick for a street car. Unfortunately you're about to find out opinions on brake pads are like arseholes.
If it's not feeling as quick as it used to, check all the exhaust manifold/turbo mounting hardware is tight and there are no leaks. Check the intake piping for loose clamps/potential leaks.
If you don't find anything you've probably just become used to the power.
