I found the previous thread on this, but wanted to revive this topic. Has anyone had experience with running stock 720s wheels on their 570s? I recall seeing a post where someone had 720s 10 spoke wheels installed. These are the specs I found, I think it means there's a difference of ~34mm front and ~26mm rear, I'm running 15mm spacers now on stock 10 spoke wheels. My gut tells me it will work.

720 Specs
Front - 19X9 41.65 Offset
Rear - 20X11 24.75 Offset

570 Specs
Front - 19X8 32Offset
Rear - 20X10 24 Offset

Drove the car today, zero issues. The 720 TPMS even worked with no issues. Final thoughts: Fronts need 12mm spacers, Rear works as is.

Your running 245 upfront with no rub at full lock?

Looks like they’re maybe a tiny bit of rubbing at full lock with the 245s. Very minimal.

I'd be curious to see how that changes with speed and turning, especially on a surface that shifts weight.

That's what I'm thinking, in a tight, heavily loaded corner.

That's really awesome for you to try. Just gives us 570 owners some options.

He is what I would call, a liar. Did you physically see it? If you take 720 wheels and put them on a super series car they poke out more than stock WITH spacers. 720 wheels with spacers would kill your fenders on super series, I gotta imagine a sport series it would be a roller skate.

Hello! That blade silver 570S is in fact, my personal car. While I think it's a little odd to call someone you've never met a liar, I do understand that as someone that considers themselves an expert in their field would have already made up their mind and this could be an initial reaction. I did do a little bit of homework on this before putting the 720S wheels on and I felt pretty good about the 720S wheels fitting without spacers, and knew right away the front would need 10-12mm spacer minimum. Probably could have left the rear as is and been fine.

Those are stock 720S wheels on my 570S with 15mm spacers all around. I did try 12mm in front, but it looks like you need 12mm spacers machined specific for McLaren since the centerbore was not able to sit flush with several brands of spacers I had. I had some 15mm's so I ran those that night hoping for the best. Drove around for a few weeks and really had no issues except some minor rubbing at full steering lock in front. I did consider running the wheels without spacers but the front definitely would have needed them since the 720S wheel has a much higher offset than the 570S. The rears I just put on because I just had an extra set laying around (I used to have a 12C and ran 15mm all around on that car as well). The gas station pic someone shared previously was from the maiden voyage at stock height.

I've actually had no issues under most of my driving conditions with 720S wheels with 15mm spacers all around and so far my fenders, and wheel liners are fine and unscathed since I work around having to do full lock maneuvers. I've felt comfortable enough with it I would finally get rid of the terrible front wheel gap on a 570S and lowered the car with swift springs. Glad to report no issues with 720S wheels, with 15mm spacers AND lowered on VR/Swift Springs. I didn't do a real world height delta but I believe the advertised height change to be accurate.

I don't get the roller skate analogy. I am old enough to have worn and used them in my childhood to remember what that felt like, but confess I spent a larger amount of time on inline - but I still don't get this, so I'm eager to learn what it means so I can possibly validate or assuage your claim.

I believe you travel for PPI's so you're welcome to look at my car whenever you're in Dallas, just give me a heads up so I can bring it to McLaren Dallas where I work. I've attached the last pic I took of my car lowered with spacers.

Sorry my experience offended you. I bought 720 wheels and put them on a P11 and my experience is my post. You might also notice the last line of my post. I posted what I've actually done, and my forethought. It's not a matter of making up my mind ahead of time. I was also correct, in that spacers on the rear is too much, and simply plopping them on there front and rear wouldn't fit properly. The rollerskate analogy is in reference to the tires exceeding the width of the cars body.

No offense really. I get the rollerskate reference now, thanks. It's been a while. There is a modest amount of poke which really for me anyway isn't excessive and at 3/4 views it's not really that apparent.

But sure I can see how this may not be everyone's taste. I push the boundaries just short of hella flush for the street. I still have stock 570S wheels for track use if I ever decide to do that for this car.

There are other considerations beyond the appearance of the tire going 10-15 mm past the body, function. There is the possibility of the tire rubbing the body on bumps, and road debris and water can be kicked up onto the body rather than being contained in the wheel well. That can cause body damage as well as damage to cars behind you.

Fortunately my car doesn't rub the tire on bumps - perhaps I have not had the right bump yet. I would think under bump the tire would camber inwards anyway. Agree with you on debris and water - there's grease or something on the doors. Car is PPF'd and Ceramic'd so it doesn't stay on my mind too much. This car's stance is actually way more conservative than either of my M3's so I'm sort of familiar with the low offset life. I hadn't really considered the projecting of debris behind me but I just compared the tire exposure clearance off of the rear bumper and it's no worse than an Arutra and the new Maserati Grecale rear tire has even more exposed tire vs rear bumper clearance than my 570. The few mm of sidewall poke shouldn't kick up debris since it's not really in contact with the road enough to collect and project anything. At least I think that's what you're getting at? How much of the tire is not contained in the wheel well?

Yeah, McLaren's aren't as bad as Porsche in that regard, but kicking up stuff behind you is a big deal when you're with other exotics making a run. Even a little bit wider can send the right rock into someones windshield. I have a chipped windshield from a GT3RS in front of me, without them going wider.

I've seen John's 720 wheels on the car. No spacers on the rear, spacers on the front. They look great, and he says there is only very slight rubbing at the front. Aside from my ultra light, track pack wheel, that is my favorite McLaren wheel.

A slight rub is enough to deter me, because in the right condition that can be a major rub.

Drove the car on the track last week, no more rub than street driving. Id say this is a win!

How did it affect the handling balance on track?

I'm not skilled enough to know the difference, and it was my first time driving a car on the track. I was doing a lead follow exercise as part of a driving course I took. It was super fun and the car felt very at home.

Generally, when you're pushing, with stock tyres the car will tend to understeer on the limit, but if you push harder with a bit more lock it will start to oversteer before the apex. My goal is to tweak mine to dial it more from understeer to oversteer, and hopefully make it feel more like the Pure 720S I've driven on track. I suspect that car had a track alignment, probably with negative camber at the front, and would oversteer before the apex at the slightest provocation, much more easily than mine does, so you could control the corner rotation with the steering wheel and adjust the car read for the exit, quite an amazing feeling. It did come at the expense of making it feel twitchy on high speed corners, but what's the point of going on track if you don't generate a bit of adrenaline???

Which track did you do?
