The sizes you asked about:
Front - 245/35-18 = 24.7"
Rear - 275/35-18 = 25.6"
I do not see a problem with these sizes fitting on the car, although it will throw off your speedometer and the car will ride stiffer with the lower profile.
The best staggered 18" sizes would be either:
Front - 245/40-18 = 25.7"
Rear - 265/40-18 = 26.3"
(options such as the Pirelli Trofeo R, RE-11, Hankook RS-3, Yoko AD08R)
or
Front - 245/40-18 = 25.7"
Rear - 275/40-18 = 26.6"
(options such as Bridgestone RE-11, Nexen N FERA SUR4)

Hey Keith,
Considering a set of these vs the APEX due to cost, but quick question on tire size. These will be going on an M2 with MP suspension (~0.5-1" lowering, no camber plates).
I used to run 275/35/18 square on my E46 M3 - super fun and beyond fantastic in terms of grip level. This is probably preferable to me except I got the 275/35 RE71R last year and found it runs extremely wide.
The 265 width seems to be better aligned to the 9.5" width wheel, at least for the RE71R's. But I can't help to think the 265/35/18 is too short for the car in the photos so far. Given your specs above, would it be better to do 265/40/18 square, since it is the same OD as the OE 19" tire? I understand there is a difference in sidewall stiffness, but I feel like it would fit the car better.
The other wrinkle is that I am considering the Hankook RS4 due to my negative experiences with RE71R wear...if those run narrower than the Bridgestone...I might just have to go 275/35
Thanks in advance
