mcguard are THE easyest locking nuts to get off..
speaking from experiance as i do a fair few, elites in rainham (quite a large alloy wheel supplier) for those that know the area, send the jobs to us..
mcgaurd are too easy, peugeot next, can both be gotten off without special tools and in about 20 seconds. hardest ones are vauxhall etc that have a spinning outer ring
infact anything that have a spinning outer ring are a nightmare,, they are what you want
