Help !!!!!!!!!!!!!!!!!
 

Can anyone help I am after some valve shims for my Impreza but it looks like mine is the only one fitted with valve shims that are 30mm in diameter even subaru are having trouble

what age and model car do you have??

valve shim dillema
 

my car is a 1997 sti 555 v-limited subaru say that the valve shims listed for my car are smaller than a 5p piece but the one's fitted to my car are 30mm diameter. the gods at Advanced Automotive, and Rodger Clarke motorsport cant help either.

Hi 30mm is the same diameter as the ones on my version 5 turbo 2000

as a 97 STi your car will have left the factory with the 12mm under-bucket shims as fitted to classic STi's from 1996.................
what your describing at 30mm is equivalent age std WRX/UK over-bucket shims - seems fairly easy explanation/fix as your car has obviously had its heads swapped for std ones at some point in its life??

we have a lot of shims in stock, cant see why an engine builder/parts supplier cant offer the same???
