Dave07997S wroteWhen compared to running square ZCP with the same 275/295 tires, you saved 2lb on the front wheels and about 1.4lb on the rear (don't have an exact weight spec for your offset). Personally, I'm fine with this minor weight penalty to get a better looking wheel, but that's just me. Your priorities are different and perhaps you actually prefer the look of the VMRs which would really make it a no-brainer across the board.When you consider the extra width, yes. Also got a more aggressive offset. The rear are 25mm offset. The weight savings meant going with the wider tire negated the weight increase of the larger rubber. I didn't want the increase of more rubber to penalize me because of weight. So I basically got more rubber, wider wheels and a more aggressive offset without a weight penalty.
Don't get me wrong, I do like your setup! I'd put it very closely behind F14 SDC in the looks department. I'm just not sure I agree with weight savings over ZCP being a noticeable advantage here like it would be if we were comparing to 18s. The more aggressive offset is nice but spacers would give you the same result.
The only real advantage I can get behind over square ZCP is the extra inch of width in the back, which is clearly something that is important to a lot of folks in this thread so I certainly don't mean to write off that factor. At the same time, I've seen plenty of other people in other threads post glowing impressions of 295 tires on ZCPs so I'm thinking the handling benefit of +1" width is marginal at best in the real world. I'm sure the added sidewall support matters more on the track, but if track use is the priority then the weight savings of 18s would be a much more important factor to consider and we'd be comparing completely different wheels.
I'll also point out that without a supercharger, I wouldn't go out of my way to have a 295 rear in the first place, 275 would be plenty and there would be no need/preference to run an 19x11" rear on the street.
Edit to respond to your edit:
Dave07997S wroteI'm not so sure you would notice a big difference in mechanical grip with a 295 on a 10" wheel versus an 11" wheel. But I could be wrong. If you venture outside of M3post and Google "295 on a 10 inch wheel" you will see that it's actually a commonly used/recommended setup across multiple car forums.The car was transformed with this, I can't stress this enough. You go with a 9.5-10" wide front with a 275 tire up front and the amount of mechanical grip is amazing. The same goes for the rear with a 11" wide and 295 outback.
