Okay guys, good news, 285/35/20 tires on 20x10 +23 front wheels and 315/30/20 tires on 20x11 +43 rears (MRR M017) fit without rubbing on my MRC car.

We did add spacers, 5mm in the front and 3mm in the rear, to improve clearance, simply because I didn't want to be so darn close to the edge, clearance would only be an uncomfortable 1-2 mm without them. The wiring harness on the driver side rear was relocated. Wheel studs appear to have sufficient thread engagement (8).

I made a couple of closeup fitment pics for reference, see below. A bit more sidewall is going to be better for ride quality, and these sizes result in a closer-to-OEM non-1LE setup in diameter.

The setup looks absolutely badass, there's a few mm of poke both front and rear, just as I wanted. Cornering grip is obviously much improved over stock. I only drove the car about 20 miles so far, no launches yet as it's still fairly cold outside and the tires are freshly mounted, but drivability is excellent, steering response feels great, no codes or stabilitrak warnings, a bit more tramlining.

Now for the only slight negative so far, the new Toyo R888R's in the rear are noisy, which I of course knew going in, just want to state it for the record. Not as bad as the OE runflats, but there definitely is a distinct background whine, which will be okay with me for a while, it actually adds some cool factor, but once these wear out (and I can hopefully improve on my paltry personal best at the dragstrip), I'll probably replace these with PS4S.
