Will SL wheels fit CLK?

Hello all,

Will these fit, or will i need a spacer??

18"x8.5" fronts, and 18"x9.5" rears
ET=25/front, 23/rear(mm)offset

Tires are:
245/40/ZR18 fronts, and 275/35/ZR18 rears

Now I know it should be 235/40/18 front and 265/35/18 rear, but will this work? Also, is that the right height for an 18" wheel? (40 & 35)

Thanks,
Joe
