Thanks for the info. I was wondering if it would be safe or if there would be any serious performance loss on going smaller (regular OE wheels, not donuts) on a 3.0 in non-winter daily street driving conditions. Taking the Z4 as an example in this case.
Ahh, I assumed the 2.0 Supra had 8f 9r because that is what the 2.0 Z4 runs. What about in the case of a Z4, which is similar enough to a Supra, running the smaller wheels with the larger engine?
Thanks. I think people usually run at least stock width or wider. In this case, we're going narrower with the oem 2.0 wheels. Potentially less grip, but will this be much of an issue? Can anyone confirm if the 2.0 wheels will fit over the 3.0 brakes?
