yea they'll work on a standard Starlet - they werent designed for the Glanza but for the Carat a JDM model, Nanglebadger has them on his car - think they fitted with only simple mods to the bumper
yea does make a definite difference the work uv done, i wish idv kept the standard alloys i had on the V now i much prefer em to the speedlines and tyres wouldv been cheaper too lol
from what I've heard its best to tape up the area then drill thru and apply a little superglue to the inside of the holes to ensure a seal then to let em dry before fitting washer jets
