Anyone have any draggy testing for light weight wheels with the M3P? If so, would you mind posting the weight of the wheels and the draggy results? Trying to see if it is worth it to spend $2k on wheels.

Save your money, it makes zero difference. I removed iirc, 48 pounds between wheels and rotors, and my car was down to the 1/100th of a second identical on a 0-60. I was able to do the same times for a little lower SOCs on the lightweight setup than the OEM setup could, but it never actually went any faster. Driving feedback was awesome though, and why I'm swapping out the new car's uberturbines for lighter setup.Anyone have any draggy testing for light weight wheels with the M3P?

Correct, it's computer limited. Also, someone on here was able to get identical 0-60 times going uphill as they were able to on flat ground.Thanks,
Interesting as why you barely saw an increase in acceleration? Maybe being software limited, as a reduction in unsprung mass should result in increased speeds.
What is your wheel/tire setup? Thanks!Save your money, it makes zero difference.

Width and weight on the wheels? Thanks! Looks like someone is using those brakes!It was a set of Jova 18" wheels and the RB lightweight rotors. This is on the P3D-, not a long range.

17.8 pounds on the wheels, 18x8.5 35et. That's pretty much the way those brakes stayed because they couldn't tolerate heavy use. One of the reasons, in my opinion, people should use caution if considering the brand. With those on there, I experienced significant brake fade hard braking on the street.Width and weight on the wheels? Thanks! Looks like someone is using those brakes!
I know it's off topic. Are you saying the RB brake rotors and pads can't take the heat?17.8 pounds on the wheels, 18x8.5 35et.

Biggest performance benefit to lighter wheels/brakes is lower unsprung weight for enhanced handling. Mostly only relevant to those in competitive timed track events. Even on the street the car will feel more responsive and ride will improve, but little quantifiable benefits.
Of course it's software limited. The LR and Performance have basically the same hardware yet the Performance is faster because the LR is limited. The question is how much is software limited vs the physical limitation of the motors and wires.I'm pretty skeptical of the idea that software is limiting the rate of acceleration, simply because that would be an odd choice. However, it is possible that some people are *traction* limited up to a pretty high speed out of the 0-60mph, at which point not much time is left for less mass to help, and at which point acceleration rates are lower so less mass wouldn't matter so much anyway.
Also some people have measured a tenth of improvement in 0-60 from light, forged wheels. Of course any experiment needs to carefully control for tire compound, width, and pressure to make sure traction hasn't changed.
But yeah don't expect noticeable difference in anything at all from lighter wheels on a car this heavy and powerful. There is always placebo effects with human perceptions and these things but the objective differences will be really tiny.
