Are you referring to 19" wheels/tires? Assuming you're referencing 255/35 and 275/35-19?

I'm thinking again that with the fat mid-range torque of the M2, on course an interesting RE-71R setup might be front 9x18 with 275/35-18 and rear 10x19 with 305/30-19. Perhaps have a second set of rear 10x18s with 275/35s on them to use depending on the course.
No, we both went with an Apex 18" setups. They're lighter than the stock 19s, and in the context of prepping for B-street, where you cannot do any suspension mods other than a single sway bar, only so much tire can really be used. Also, I think B-street limits tire width to 285. STU does, so assuming BS does as well. With regard to tires, the RE71 comes in a 285/30-18, which can work in some square setups (but with coilovers and camber plates), and it comes in 19" 285/35 and 305/30 as you mentioned. But the EC7 doesn't come in a 19" with proper offset for the M2. I wanted a matching set (style, not diameter) in stock widths, so it really boils down to the EC-7 being the only choice for me. I would have been OK with 19" in the rear though. Apex's FL-5 is my favorite wheel, but you can't get it in a 10" that will work on the rear of the M2 in any diameter.
