i'm gonna guess rota p45R. to fit them on the 3, i'd imagine some coilovers, a fair amount of camber and a fender roll and pull would be in order, and some stretched tires. i could be wrong, though.
edit: google p45R image search comes up with this post from the p45R thread on evolutionm.net
and you cant run those .. the p45rs are way too low of an offset to run on the speed 3 .. you can however run the p45F ..... but they wont have the concave face like the R's do
***EDIT .... didnt even see the poster above who linked to the same thread.. oh well TREED LOL****
