From my own "research" lol....
When chasing 0-60 time only, I launch around 3300rpm with a quick clutch slip, not a dump. You want some wheel spin to keep the revs above the torque peak but not full blown burnout. I do find this trans to be very fast shifting friendly, so I bang 2nd around 7200RPM. Again the wheels typically come loose a little. From there I just ride it out all the way to the limiter in 2nd. That gets to exactly 60. I was doing 5.7-5.8 that way. But if I change that to how I would drive doing a proper drag race and not hitting the limiter it adds about a half second. If I shift to 3rd again around 7200RPM then the time to 60 was taking me about 6.3 with a nice chirp from 3rd. 😁
 
Thanks for the info. I'm not able to get any better than the high 7s with my Dragy. Though I know I'm not the most aggressive shifter. The most disappointing thing is that I can't get above .5 Gs of acceleration. According to the Dragy, my mothers Camry hybrid pull just about as hard as the BRZ. And gets about the same 0-60.

Thinking hard about a higher rear end ratio to increase rear wheel torque
Electric motors have gobs of low end torque which gets them off the line. Work on the driver, maximize what you have before throwing parts at the car.
 
@TRU-BOOST thanks for the info. Being an old V8 guy, dumping from a high RPM makes me feel like I'm being abusive to the car.

Unfortunately bouncing off the limiter did't leave the car at or above 60 mph long enough for the Dragy to recognize it, and wouldn't record that stat. Next time I'll get aggressive with the shifter. 6.3 is something I can chase after.

It is definitely possible that in reality 2nd doesnt hit 60 and its a minor speedometer discrepancy. I havent tried a gps based timer.

I don't drive for skill, I drive for entertainment. This car just doesn't "feel" as aggressive as I would like. (Or what the Car and Driver 0-60 times would indicate it should feel like).

I've been looking at Mustangs and other "quicker" cars, but I really like the twins interior lay out and practicality with the exterior look and the car's road feel. Plus I've already bought this one.

So I did a "little" experiment.
What did you do to your BRZ today?

By installing a 4.67:1 diff, I'm able to change the over all "feel" of the acceleration in every gear. Plus it leaves the car basically stock. You could even make the argument that by reducing the perceived "load" on the drive train, that I'm reducing torque stress. But not necessary wear because I'm increasing the drive train RPMs.

I'm willing to take the hit on mileage because this is my toy car. I treat this car like owning a boat or a small airplane. You can do practical things with them, but they don't do the practical things a efficiently as other options. You bear the cost and time for the "experience" they provide.

mustang dyno 1/4 mile here it can be done 2023 with the gr performance exhaust View attachment 26656
I do believe the ¼ mile can be done under 14 seconds, but that 1.57 60ft will never happen in real world conditions in these cars. They are too light to get that kind of traction off a launch. And if you put sticky enough tires on there to achieve that your axles will turn into pretzel twists. Other than that numbers for the rest of the run looks totally feasible. I think we can chalk that 60ft time up to being strapped down to rollers.

I will say it felt like I was spinning my wheels a little too could be faster
