no they arent actually.. the original bolt pattern is 5x120 but after finding out adapters pushed them out too far i got them redrilled by a professional to 5x100.. Its annoying there isnt room for three pcds cos i doubt my next car (whenever that may be) will be 5x100 so i wont be able to use them anymore. Sill, if i can find the fourth 20" one then i can use them instead.
ps i have a set of aston martin 19s that just need some adapters and wobbly bolts to fit if anyones interested.. tempted to try them on mine as they are seriously lightweight.. with a tyre on they weigh about the same as a standard 18" tt rim without a tyre, that could be a 40kg saving overall !!
