I want to run Cosmis XT-005R wheels on my 2002 Is300, but I am concerned about how they will fit. I installed the LS400 4 piston BBK in the front which means i have to run a 15mm spacer in order for them to clear, since the stock 17x7in wheels have an offset of +50 will a 15mm spacer turn it into a +35 offset? and if so would I be able to run an offset of 25mm without the spacers? My fenders are rolled and i am lowered about 2 in. on coilovers but I can raise them for clearance, I just want to make sure these wheels won't hit control arms, my brakes, and won't poke pasted the fender. For tire size on this rim I would do a 225x40R18.
