Great video, love to see these with actual data backing it up. Definitely one of the best things you can do to a car that you plan to track... Tires, tires, tires, AND less rotational mass!
Oh wow, I didn't think light wheels would actually make it on the dyno. Pretty nice, it means that much more on an actual track where braking and cornering are involved. It would be nice to do a comparison on times with the different wheels sets and same tires.
Light wheel or small wheel increase horsepower because less moment of inertia
It improves gas mileage also. Instant upgrade all around.
@@falahsamisyahdan7962 however the faster you’re going the slower the RPM increases and the benefit gets smaller and smaller… same thing with flywheels the faster you accelerated the bigger the difference you’ll see… on something where you’re going for top speed like salt flat racing there’s no benefit in light weight rotating mass because the the change in momentum is a lot slower
I tried liking this video twice, nice testing and explanation, I could never find a real answer as to how much performance you gain from lighter wheels online and now I have an idea
This is why I love you guys. You put your money where your mouth is. You don't just say that they'll give you better performance, you actually prove it.
a 6 hp difference is essentially a run to run dyno error, zero proof actually, but hey man stay easily fooled as you stare at bright shiny objects, and oh yeah, don't forget to waste your hard earned money on a new set of wheels that won't even get you a .10 better times on the track in the real world (ask me how I know, I just dare ya).
Not sure if all four wheels were spinning on the dyno, but if not, the perceived improvement should be doubled. Since the front wheels need to spin in the real world too
I don’t understand. If the fronts were spinning on the first but not second test the I could understand
Horsepower will not be affected by the front wheels same as a lighter battery will not affect HP. Will affect cornering and hamdling tho
@@martinlebreton6391 It'll effect acceleration alsob
Super cool stuff guys
I’ve always wondered this....not anymore!! Thanks Steeda great comparison. 👍🏻
Happy to help!
My bracket numbers went down .2-.3 seconds when I switched my 2013 stock 18 inch wheels out for some steeda lightweights.
This video is cool to see, but surprisingly the results aren't the same always like this.
I installed a 240 Kit on a 2008 Hayabusa and it lost torque and gained 3hp. And percentage wise is much more of a difference on a 175 hp bike vs a 475hp car.
I was shocked when I saw the results. I expected similar to what you recorded. I would love to take one to the drag strip and test it compared to a similar bike. That would show the true results of the change.
I'd imagine the effects across the board are amplified according to the vehicle's power. Less power to begin with, the more loss in proportion.
any idea what the stock weight of the 19" ford fusion rims are?
Also one thing to note is less rotational mass in the rear wheels is more impactful than less rotational mass in the front wheels because it’s less rotational mass in the drivetrain.
For power, 100%. But you’d be surprised how much less rotational mass helps up front with steering feel and responsiveness! -Chris
I think something that Steeda should point out is that the stock 19” setup is a larger overall diameter than the 18” track setup (27.7” vs 25.4”). That has an effect on the dyno. As well as tire pressure, especially when looking at single-digit HP. Not really a dig at Steeda: the smaller diameter track setup still showed a 6hp gain.
Exactly
this video was all smoke and mirrors, a bright shiny object to stare at essentially. 6 hp on a 475 hp car is a run to run error at best, this video shows zero proof of anything other than the fact Steeda has stuff to sell you.
Buen trabajo!!!
This is interesting that there's that much performance ...and on a dyno.
My 2012 GT/CS stock wheels weighed close to 28lbs (only the wheel) and then the tires on those were some 245/45/19's that I want to say weighed closer to 25-26lbs... so right at 64 lbs, and i swapped those out for some 24lb lighter wheels, but the new tires (285/35/19) were about 30lbs... so the 4 lbs i saved I gained back in tire weight, so i'm curious if the same tire on a lighter wheel vs same wheel and a heavier tire makes much difference, probably not that much... but I've also been told my exhaust is about 20 lbs lighter than the stock exhaust (bassani cat back). I'm starting to wonder if the wheels did more than the exhaust xD
What is the tire size
What is the side wall
Awesome vid! What are tire sizes on the 18x11 wheels?
315mm
Maybe a 1/4 mile and speed trap test would show the real improvement.
Came here to say this. Dyno numbers are like shoe size. They're just assumptions until it's time to perform.
@@Carl_Jr Dyno numbers are not assumptions lmao. However they should have did 3 pulls with cool downs for each tire in this test. One pull plus or minus 5whp on a 500whp car is not enough data.
@@na4valve They are assumptions. No two dynos are the same. Not two types of dynos are the same. A drag strip run would tell the tale not this crap.
Love the content! How were you able to fit the 18x11’s up front?
Our 1" spacer and that's it! Hope this helps! -Chris
Steeda Thank you!
@@steedaautosports wow, and no rubbing issues??? I can't imagine you can daily the car with a wheel that wide up front
@I have 315’s square, with -3.3° camber up front. It would be fine as a daily driver, if you’re not dealing with really crappy roads.
@@utoobia so if I'm understanding this correctly;
In order for me to have a square setup AND still be able to rotate all 4 wheels, all I'd need is a 1" spacer up front?
That has no rubbing issues ither?
Great video, Steeda! What are the mods on the car that you dynod?
Hi Steven Thanks for your kind words, here's a link to the current build sheet
www.steeda.com/steeda-2018-q500-hpde-car
@@steedaautosports my 15 GT has a ton of Steeda upgrades... There's nothing better 👍
Did the downsizing wheel size play a factor in the hp gain?? Or was it just the weight saving. What if you went from an 18 to 19 “ but still lighter wheel. Would you still see a gain. Or no bc of the bigger wheel & gearing
If you're going to a larger wheel, but still saving weight overall, the gains are still there
Just curious. Is it 12lbs per corner or 12lbs all four tires? Is the circumference the same?? Really appreciate it if u can share. T.q
That's per corner.
what is the affordable lightest metal for wheels? & in which brands?
Aluminum.
What is the tire size in the beginning I saw 315/30/18 but then on the dyno I saw 315/40/18
315/30-18
Does the car have 6 piston breaks? Will this rim let me run a big brake kit?
Yes, these 18" wheels accommodate factory GTPP brakes, as this car runs those brakes.
So if I go from 32 lb 19 inch stock wheels to 16 lb 17 inch wheels (128 lb total reduction in rotational weight) in my Mazda cx5 turbo, will I notice a big difference in acceleration?
No, because it’s a cx5 and there isn’t much acceleration there to begin with
Hi, I'm tore between buying these Apex wheels or your new steeda trident wheels. I know you list the trident wheels at 24.5lbs for size 19x10s. Are the Apex rims close in weight for the same size? Also do you know off hand how much do the stock pp1 wheels weigh?
Hi there, Apex EC-7 and our Trident wheels both weigh the same for the 19x10. The Apex SM-10s weigh about a pound less. Compare that to the PP1 wheels 19x9.5 that weigh a bit over 33lbs. Hope this helps!
@@steedaautosports thanks that info helps a lot. Looking forward to getting the trident wheels.
Wow that camaro was a lap ahead and still almost past you you at 1:05
Do these 18” clear the Brembo 15” PP1 rotors and caliper?
Yes, our red HPDE car is a PP1 car. Hope this helps! -Chris
Steeda thank you for the reply
unsprung weight vs weight of a rotating mass , I think lighter weight wheels are better but it makes little difference , the major advantage is on suspension components and fuel consumption
fuel consumption is proportional to the effect in aceleration so cant be a little difference in acceleration and better in fuel.
The bigger effect is in suspension, that was correct, the ratio spring/unsprung change a lot.
There’s no need to speculate, they demonstrated the results in this video.
What was the weight difference with the stock wheels to the one you guys put??
they said in the video, 12 lbs per wheel. 64 vs 52 lbs. So they lost 24 lbs and gained 6 hp.
@@a.wheeler7731 12x4=24???...🤔
@@Dr-CZcams rear wheels, 11 month old comment though id have to rewatch.
@@a.wheeler7731 12x4 is 48pounds!! That's a lot with a simple mod!
Will a 295 front tire will fit your apexEC7 18X10? Without any rubbing on the track?
Hi,
A 295 front might rub slightly but it is dependent on your setup.
@@steedaautosports thanks for the reply. I have 3/4 drop in the fronts. Was looking for these apex Ec7 18x10. Tire im looking at is 295/30/18.
@@Jmab-rv7jc It's been a year since you replied but - Did 295 fit in the front with no rubbing? Everyone i asked says 275-18 are the max for the track.
@@HFIntegrale i did 285 and was fine. Coz the wheel is smaller. But 295 might
@@Jmab-rv7jc So lock to lock under load is not rubbing with an 18inch 285 tire?
With lighter weights the car will go into corners a lot easier and the suspension can do it's job a lot better. That's the main reason for me to use lighter wheels and tires, not the horsepower alone.
There are tons of benefits to reducing rotating mass! -Chris
Can you fit a 19x11 squared set up on the mustang?
Yup! With a spacer up front as the rear requires a different offset than the front. Hope this helps! -Chris
What wing is that?
Here you go!

How much time have those wheels spent on track? Curious how they like the abuse?
We just installed them on the car and they've been to one track day. Our customers love Apex wheels, but we'll be sure to keep you updated through the channel here on how they're performing! -Chris
Steeda my great debate is 10 wide or 11 wide... hmm
The Nitto tires look like a noticeably smaller diameter?? I find it strange you give the full tire size of the Pirellies but not the Nittos?? This seems like it alone would make the difference.
Yes, the 18" Apex Wheels are a smaller diameter than the factory 19" wheels. However, they're much wider at 315/30-18 fitment meaning more rolling resistance than the factory 275mm tire as well. Hope this helps! -Chris
@@steedaautosports on the video I saw 315/40/18
Good job thanks is always power to wt
He forgot to mention that the hp “gain” is doubled providing the same weight reduction on the front and that braking would would get the same “hp” advantage.
That’s a good point! -Chris
Do a video in the same manor with a aluminum driveshaft
We'll see what we can do! -Chris
Would like to see this!
I would like to see the difference as well.
I just upgraded my s197 to aluminum driveshaft and the car feels better but would like to see a dyno comparison.
@@chrisrcarraher8800 does it feel any quicker or just tightened it up?
Remember 1lb of rotational mass is 4 hp of static mass so 12lb is like removing 48lbs from the car
Does this come with lug nuts?
Lug nuts are sold separately. -Chris
@@steedaautosports just bought the ec70 18X10(ET40) and 18x11(ET52) from your site. I have trackday in dec. you think the wheels will be ship by then? And can you pls send me a link for the correct lugnut so i can buy them asap thanks @Steeda
It could be an anomaly. You basically backed up your first dyno pull with a similar number
It's a rather wonky test. It's not at all apples to apples.
That's great, but let's talk about the fact that most APEX wheels are 800 dollars or more, where your "standard" 18-20 inch wheels from American racing/Niche, etc... are only like 250-400 dollars. So you're talking over $3000 dollars just for the wheels, for less than a 5% gain...
Did I miss the weight difference between the two setups, or was it not mentioned? Curious to see weight percentage reduction versus HP percentage gain. I know it is not exact and we need many comparisons, but just curious.
12lb per corner roughly
and that's only showing the difference the weight of two wheels made.
Throw it on an awd dyno with skinnies on the front so you're turning all 4 wheels like real world conditions.
Compared to stock, its a big deal. Not only are there peak HP gains, but actual Weight lost in the car. double win.
Dyno don’t lie, awesome vid
dyno do lie. you have no idea what you are talking. different strapping force and tires and heat soak alone will give you different readings let alone weight of the wheels and tires etc. ANYONE who knows anything about rolling dynos will tell you the same thing. This test is pure garbage. GO talk to a dyno expert and they will tell you the same thing. this test doesnt prove shit.
And less weight means less hard the engine has to work to get the mass working. Less hard the brakes have to heat up to slow it. Weight is a weird phenomenon. Drive shaft. Wheels battery some choice stripping of trunk and interior bits. I bet anyone could shed 100 to 130 lbs off the car. Oh yeah that stupid exhaust. That's gotta go too
A quarter mile or 60-130 would’ve been a more complete test
This is a HPDE car, not a drag car, plus it’s a manual. To many variables in the 1/4 mile.
What happens? You lose 1/10th of a second on the 1/4 mile. The gain is insignificant for everyday road drivers.
It lost a little torque
+6HP on an already 475whp set-up is simply slightly different characteristics in each run. A Wheel is "circular" and the weight savings aren't providing any significant advantage with the transfer of energy from the transmission along the axle through the drive shaft.
Where the lighter weight comes into play is relative to the handling ability, especially in the control/trailing arms and suspension.
Run a car on a Dyno 10 times and each power measurement will differ (lower or higher). They are used to "tune", not necessarily report power.
You are so wrong buddy. Of course power to transaxle matter, engine requires less force to spin the wheels and moves easier, so that improves the consumption as well! It's general phisics!
The energy required to spin up and down the rims is miniscule. You would never notice a difference under power. This is all horseshit. You WOULD however notice a difference in handling, assuming you have the car set up correctly. Less sprung mass works wonders for the suspension
*Unsprung mass
On the dyno you are not accellerating the mass of the car!
@@paolonieri473 Duh?
@@johns.1898does it really need to be said that you wouldn’t notice? I mean they clearly demonstrated a change of about 6HP. Are you going to feel that as a discernible change? No, but it’s a gain nonetheless.
In theory the GT350R has more horsepower than the regular GT350
I switched to lighter wheels on my 2017 Gt 350 and it made a noticeable difference in acceleration . Saved 9 pounds per corner! Those stock wheels and tires weighed in at 60 pounds plus. Shame on Ford!
Yes it should. The the OEMs rate them the same as they take the rating from the flywheel with the engine not in the car
my wallet wants to dislike this video
You crash. You still crash. No. Matter. What.
Remember, lighter equals weaker.
Not always true, especially in materials designed to handle hard use
Completely untrue.
