so what's the recommendation on a true square winter set-up on an M2C with these? 19x9.5 ET28? running 245/35 tires?

Our go-to recommendation for a M2C winter setup for the SM-10/EC-7 design utilizes the following specs:

Wheels:

Front & Rear: 19x9" ET30
-Direct fit

Tires:

APEX Staff Pick: Front & Rear: 245/35-19

Performance Winter tire recommendations: Michelin Pilot Alpin PA4, Pirelli Winter Sottozero 3, Dunlop SP Winter Sport 3D, Vredestein Wintrac Pro

With a 19x9" ET30 wrapped in 245/35-19 tires at all four corners, this setup will be a complete direct fit on a stock M2C and will have no issues clearing the larger 2NH front brakes. The 19x9" ET30 is a bit better suited for a 245/35-19 tire, as it allows for a bit more sidewall, resulting in additional protection for the rim of the wheel. With that same tire size on the 19x9.5" ET28, most winter tires will be a bit stretched, which isn't ideal for off-season driving.

Hope this helps!

Pulled the OEM BMW wheels and tires (PSS - great rubber) and put Apex SM10 wheels (9.5 & 10.5 x 19) with Pilot Sport Cup 2 sneakers (265 & 295) on the car.

Been running the Apex EC7 with the same size spec R compound tires on the track and really like the feel.

Came home from the track a couple of weeks ago, didn't change them out, did a bit of street driving with the track wheels and was blown away with just how much more traction they gave. Second gear rear wheel spinning was a breeze with the 265/35 PSS, now it's no spin and just forward momentum gain.

My present PSS are worn out at 10.1K miles (inner front shoulders are shot due to finding a good track setup and not having camber set correctly last time - waaaay too much). I probably have 20% of the tread left front and rear.

I'd always said I'd put new wheels on when it was time to change out the tires and since I like the Apex setup that's what I went with again.





The sidewalls on the Pilot Sport Cup 2 are thicker/stand out just a tad more than the Toyo R888 so my spring perch adjustments are rubbing on the inside sidewall just a touch (about a millimeter). I'm waiting on 3mm spacers from Apex - should be here either tomorrow or Wednesday.
