As a cyclist, it's well known that wheels and rotational weight makes a huge difference in how quickly bikes accelerate, decelerate, turn in, etc. The lighter weight is exponentially more important when it's on a rotating wheel than on the rest of the bike/car.

[@robingielkens9795]

Angular momentum is determined by the moment of inertia, which is quadratic for wheels

[@pjay3028]

True, although the very large diameter of bicycle wheels and the greater proportion of the overall weight of a bicycle that the wheels contribute (compared to a car) mean the impact of lighter wheels on a bicycle will be hugely more significant.

I once swapped out the standard mags on my 2013 Audi S4 for some Advan racing RS2's and the weight difference was 12.6kg to 8.1 kg i.e. 4.5kg saved per wheel. It was quite noticeable in acceleration, braking and turn in.

[@kirk911constantine]

For those of us on the “other side of the pond” who likely will never get to experience the ‘Ring, it’s fantastic to live it through these videos. Would LOVE to be behind the wheel of the GT3RS. Heck, I’d love to be in the passenger seat to experience that. My time in a NASCAR and taking my GTI to the local track only whets the appetite for more track experiences. Great video, James.

First of all James, im really really happy for you to be able to experiance such things and how everything developped. Remembering the moment on the airfield when u asked if you should make your own channel into the cam of Sam I believe it was, its just great to have followed some of your journey, not all of it. But coming now back to your videos is just wow! Priviledge to see this content and your doing such a phenomenal job of transporting your experiance to the viewer. I believe you when your saying that you recognize the difference - I would not believe many people such a comment... Thank you!! And hopefully you have had the chance of getting to know the German pendant of you already? JP from JP Performance? You both would be so perfect together and would fit for a meetup between buddies - not just on youtube, but on personal levels I think. Ben from the Porsche Museum tour can hit you up with his contact details... They are great buddies too.

[@rudik5496]

Big respect for driving and talking at the same time! Next level!😮

[@TheBobodrink]

Love this content! I have been doing comparisons like this with my 997 GT3RS and found out that just swapping the wheels is not enough. The suspension has to match the lighter weight, where it didn't do so well with my 997 stock shocks with mag wheels. It was too light on its feet its bouncing around too much and can't put the power down. Realized you need new suspension and tire pressures to match.

[@andrewholt3849]

Great video. I was aware of the weight saving per corner/ wheel with the PCCB ceramic brakes and had seen magnesium alloy wheels on the McLaren F1 with Gordon Murray. I don’t understand what ‘unsprung mass’ is with reference to weight saving. It must add to the momentum to overcome m.v (mass Kg x velocity m/s ) when accelerating the wheels, but having more mass must help with high speed cruising on a motorway.

[@francoisguillamot1887]

Great video ! Shouldn't you reset the supsension too with the lighter wheels to have a chassis completly set up ?

[@jondoe5590]

Lightweight wheels, or even lighter than stock wheels make a big difference. I won't mention my cheap car but I got some -4lbs per corner wheels recently. After a month, I am getting 1.6 mpg more! It definitely feels like its gained some hp too! The hp may be placebo but the mpg increase definitely isn't!

[@MG-iu9yj]

This is so true, I changed my or wheels which weighed 14kg each to a set that weighed 8.7 kg and the difference was brilliant. It now rides over bumps better brakes better, turns better, everything is a step on, it’s how the car feels which is so much more enjoyable over all, can’t recommend it enough.

[@981_pdk3]

Great content and video. I’ve done similar on my Cayman moving from 19” stock wheels and tyres to lighter 18” track wheels and Trofeo Rs’. Definitively agree better braking corners speed and acceleration. The con is once the heavier wheels gain momentum and your on the throttle it’s kind of smootherAlso Porsches pull well in the upper revs.

[@videomaniac108]

I just got a set of 19" Litespeed forged magnesium wheels to replace the OEM Rays forged aluminum wheels on my 370Z. The weight savings per corner will be about 9 lbs and I'm eager to see how it feels after I get them installed.

[@iankuah8606]

It's not just direction change and braking that is improved by lowering the unsprung weight. Acceleration benefits too. About a decade ago we did a test with G-Power, the German BMW specialist tuner in Bavaria, to see if lowering the unsprug weight with their forged alloys made a difference to acceleration to speed. With a saving of about 3kg per corner we measured a consistent 0.1 sec improvement in the 0-100mph time with digital test equipment. The explanation for this is that the available power does not have to rotate as much wheel mass off the line and through the speed range. As Colin Chapman famously said, "For speed add lightness!"

[@BugsyBun]

When reducing the unsprung mass, I assume you will have to adjust the suspension to cope if you wan't optimal settings?

Did I hear it bottom out on the light weight wheels ?? Fantastic video

[@Cloxxki]

I used to be a mountainbike racer. Minute changes to the bike, such as weight savings in the wheels, were very strongely felt. Getting this changes to express on the stopwatch was basically impossible, and dong the math, it would all become apparent. Weight loss in wheels FEELS a lot different, but it doesn't actually make you a lot faster You're feeling the wheels, but still need to bring along all the other kilos in rider and bike. If the car really feels better, it's a cool upgrade. If laptime matters, I guess math can work out how much the wheels will help. To measure, you need a whole bunch of free laps with a pro driver.

[@gtclubuk]

It should be obvious when you think about it that light weight wheels are going to improve performance in virtually every aspect. People focus way too much on this unsprung mass thing though, as your man said, its rotational mass that is really affected and that makes the difference in what you are feeling. Do this small experiment. Take a wheel, not a car wheel but a childrens bike wheel or similar, and just hold it on a spindle and change it's direction as if you're steering it. Now get someone to spin the wheel and do the same thing. You will feel the difference. And that wheel will be spinning at about 10mph, very slowly in comparison to a cars wheel. It'll soon put the whole thing into perspective. Essentially rotating mass s stored energy, just like a fly wheel, and any change to that energy, be it braking or a change of direction, takes more effort. Reduce the mass, reduce the energy, reduce the amount of required effort. Pretty simple :)
