I'll come clean. I saw a previous post that convinced me that this group is tech focused, including tires for track days. I'm bombing this list even though I don't have an M3. It's more of a general question for track days posed to knowledge drivers. I know autocrossing with SCCA we weren't allowed to change rim width, but we'd still mount wider tires and go faster. I guess I'm not too uncomfortable with using any rim width that is in the recommended range for a particular tire, but will there end up being more wear along the outer edge? General opinions on any impact of different rim widths on track performance are welcome. The tires will be on an extra set of rims and will only be driven on track days.
And to come completely clean, even though I really like the MSport suspension on the '26 330i and I suspect it would be a fun challenging speed-maintenance car on track, I'm still playing with the car I already had. It's a 2015 Cayman GTS. I want to move to 18" rims and bump the tire width a bit. It would be 245/40-18 in front and 275/40-18 in back. 8" front rim. 9" rear. Other than the rim widths I think the combination would work pretty well.
And yes, thanks for the reply.
