welll when i do angled wheel blurs, i select the wheel with the polygonal lasso, than i take the whell, and rotate it so it is straight, up and down. (like hold a pencil up to your monitor, vertically and match it up straight) then, drag it out left or right, untill it makes as perfect of a circle as possible, then just look to where the center of the wheel is, and adjust your radial blur accordingly. Then just re-transform it back into place....hope this works for you man, if you dont understand something, p.m. me. anyways, i liked these shots other than that wheel blur problem, nice job!
