whats the best locking wheel nuts to get for an 05plate? People say McGuard but they stick out quite far. any other opinions? what spec do they need to be size etc

 

There are 2 McGard locks that fit Imprezas. The most common one is part no 24152 which sticks out a lot (I've got these), but part no 24013 is much shorter and I think is a goldy colour, so you could try to find a set of these.
