Wastegate "Smart Shim" for the 944 Turbo Wastegate. The
first and only wastegate shim that doesn't require
removing the diaphragm pot to install. Just slide it in!
Shims are 1/16" thick and made from stainless steel. You
can stack from 1 to 3 in your wastegate to adjust your boost. We don't recommend more than 3. There is only
1/2" of valve travel in the wastegate. If you install a
1/16" shim, you lose 1/16" of that travel. So 1/2" of shims would keep your wastegate from opening at all.
