Old School Staggeriness, anyone?

In drag or high power grip RWD scenes staggering the other way is more common with smaller rears like 17/16 or 18/16.

Talking about tyre widths, if you lust after that staggered look I say go for it. Otherwise your cash will be better spent on better quality rubber all round.

This isn't accurate. Many high powered cars use larger diameter wheels in the rear. I can't say if it is because of the power - but I suspect so. Both my C5 and C6 vette had a larger diameter in the back.

section height not section width.

Top fuel dragsters use very small wheel height to transfer power to the tires quicker. But use an big diameter rear for the most contact patch for the dialed in power. and very tall skinny tires for optimal low resistance and aerodynamic aid. You will see setups like for example...17x5 Front / 15x10 Rear

In road course, this also could occur depending on the output characteristic of the vehicle. With more common 17x6 fronts and 16x9 Rears on HPDE teams that really focus on maximum grip on the rear drive wheels.

But this BRZ/FRS is not suffering from the lack of traction, even with low resistance eco tires. So it would most likely negatively effect the car if you choose to set up the car this way. Im guessing a good 17x8.5 all around with performance non-slicks tires will be the best street setup. But id be more interested in staggering the offsets in favor for lower offsets in the rear.

If the BRZ/FRS is putting down +500whp, then the factory suspension and tire setting is now not balanced...aka not properly dialed in to accept the output.

Thanks, I get that. I was just referencing that for street cars that it isn't the case. Can't think of any real reason why street cars would run smaller diameter in the rear - but I may have missed if this was for non-street. On the flip side, many production cars (modern) have larger diameters in the rear and I'd wager it isn't for looks.

Come to think of it many open wheel racecars have larger rear wheels (diameter) too. All that aside, it certainly makes sense for certain traction needs.

I've also seen the opposite on big power Supras. 18's front and 17's rear. Ugly but they get more sidewall in the back to hook up better.

Yeah it is but you are talking about a greater overall diameter not just wheel size.
