If the Apex'i ones has the same body/outter design as the MRs, I doubt you'd fit 17x10 +18 up front if its slammed. I had MRs and I had to slap 8mm spacers to clear the front strut, while slammed to the ground on 17x10 +12. The inner lip of the rim was basically touching the spring. If you raise the car up where the spring and collar are above the rim, then you might clear.
But at the same time, I'm running Topline Aragostas out here and I have no issue clearing 18x10 +18 up front. Design is alot skinnier than the MRs.
