[s-cars] What's the depth of your wastegate screw?

Stock AAN/ABY WG screw depth is about 11 mm if memory serves, measured from
the WG cap. MTM recommends indeed 5 or 6 turns if the stock spring is still
used. On stock SW, WG depth isn't very relevant, but by the way, who's
still running stock SW in an UrS car? :-)


HTH,

Mihnea
