Interesting video and great find! Alfa Romeo’s 🐍 engineers need to slightly redesign that inner suspension component 🔩. That’s one reason I’ve never been keen on changing modern cars suspensions and alignments.
Just like Ducati, had on their outer engine casing an oil sight-glass. It was directly where the right foot brake lever was. So if the motorcycle 🏍 ever fell over ⤵️ the right brake foot lever can and did punctured the sight-glass, leading to catastrophic engine failure. Recently Ducati engineers have moved the oil site-glass up ⬆️ a couple centimeters to avoid that potential problem from happening again so the rider is not left stranded on their expensive adventure motorcycle.
My 2017 QV is fully stock and I have the exact same rubbing as well, more on one side than the other
thank you for posting your feedback its for sure crazy and my alignments have always been spot on and it only happens on this set of wheels
I have a 2017 QV, stock suspension with the same winter Alpin A4s on Five holes. No rubbing.
My brother's 2017 has no rubbing at all.
I noticed that in this car you can't put anything heavy on the trunk
Maybe try putting some clay on the different spots then mount your winter wheels, run the car, and that should definitely tell you where its coming from?? It works for clearancing valves, maybe it will work here?? Just a thought. (Actually masking tape would probably work as good if not better??)
Definitely not that any bolts on brake caliper as the wheel and caliper distance don't change under the load.
It's the bolt you want to grind down. Lines up with scratch marks
very strange, i dont think that the suspension would flex so much especially on only 1 side of the car. personally i think something got into your wheel and scraped the paint off and fell out again. it would both be noticeable by feel and sound if something was seriously wrong to flex that much
this is definitely not from rocks or debris based on the visual of the scrapping it seems constant. with the winter tires since they are bigger based on their winter design on bad dips i do hear a chirp and noise on compression. Also the Kw shock bodies are thicker than the original rear shocks and i think that is where it rubs on the outer edge.
@@autofanaticcars Check sway bar bushing.
Yeap lowered and alignment play havoc unfortunately. Same with anything wider than stock tire wise. I've decided to switch everything back to stock width and a minimal aggressive alignment just to avoid these annoying issues
and whats crazy it only does this on the 5 hole wheels for winter, the winter tires are OEM size but physically a but taller and wider than the Pirelli Corsa tires and the Micheline 4S i have now. this is really a mystery because I can not find out exactly how this is happening on that one rear wheel.
@@autofanaticcars I forget if the tenicos have a different offset compared to the 5 holes but feels like it based off what you're seeing.
what I need to do is measure the inside ID of both wheels to compare I have a feeling the 5 holes being cast has a smaller ID which might be the reason but il do this soon and let everyone know.
I have never heard of any issues with folks running normal geometry.
these cars stock geometry leave so much on the table as far as handling and grip
Add a dab of yellow or other bright color paint to the top of the suspect bolt heads; after a week or so of spirited driving the culprit will be revealed and remedial measures can be taken.
Milwaukee just announced two new M18 polishers... A medium and a large...
I have those issues and have ran through tires very quickly. It’s just the back that does it.
I am wondering if it could be buildup from Ice and dirt during the winter months causing this issue. Does it do it on the summer tires ????
never did this with the summer tires it was my rear negative camber and as the car leans since i drove it so hard it would rub the inside of these wheels, very crazy but these cars have so little tolerance under the wheel well areas.
Does the car have an IRS? If so it could be that the IRS is off from the factory. I know for the mustang, Steeda makes an alignment kit with bushing to align the car properly.
Biggest difference you noted was winter vs summer. It could be accumulation of snow when driving that hardens to ice and over time acts like sand paper on your inner wheels paint. Just like the fender well accumulates snow when driving behind the wheel. If it was the bolt you would have gouging marks into your wheel, it’s too smooth of a wear to be metal on metal grinding. Plus if it was the bolt the lines would be wavy with the suspension flexing.
Calipers bolts won’t have any part in that as the wheel is mounted to the assembly that does not tweak, if that’s happening your studs you be stretching causing the wheel to misalign with the hub.
@AutoFanatic My my ‘18 QV I’m running KW DDC coilovers and ideal racing rear control arms, with OEM 5-hole with winter in stock sizes and OEM forged wheels with 255/295 cup 2’s. My Front alignment is 6.5/7.1 deg caster, -1.1 deg camber, -1/32 toe, Rear is -1.7, toe -1/16. NO rubbing in either of the rear wheels. How does your compare?
I have more front and rear camber than yours and my toe is a little different but its crazy has even someone just reported their 17 is bone stock and theirs rubs just like mine. I wonder if this is model year dependent on these cars and the earlier cars are more prone. I hope someone with a 19-22 model can report back
Lower arm bushes? Check those, will cause extra movement. Mine went at 55,000KM. You have to replace the whole lower arms as they have integrated bushes. -2 is not excessive camber. I’m running -2.5 on rear, Technicolor wheels. Never seen a scratch like this.
how hard are you driving your car in corners? this seems to be happening during winter when i snow drift often with the car which puts excessive lateral load on the suspension.
@@autofanaticcars pretty hard, I track it regularly.
@@autofanaticcars what is your toe angle, if any, on the rear?
I had sort of the same issues on the Subie when I put the Bilsteins on, it was the control arm and it's bushings under load with ecssive camber ect.
Do you have a gopro? If so mount it under the car, point it at the area and go for a drive. That should confirm what the exact issue.
i plan to do that when it warms up the weather now dropped back into freezing winter temps.
I have a '16 full stock with about 36000km (20000 miles) and no rubbing on the wheels.
but how hard are you driving it through corners to load the suspension up enough i think everyones usage will vary
Think not all wheels are made the same honestly speaking.
Had the same issue with a set of 18s, 1 set fits perfectly, other set brake calipers knocks the weights off. 😛
Interesting, what I wanna know is how are your wheel faces so perfect!? The shit gravel they throw down where I'm at has really taken a toll on mine.
crazy observation of owning my Alfa QV all these years, the 5 hole wheels have a much flatter face profile and for some reason they do not get peppered with rocks like the Technico wheels that have the curved concave spokes. the gravel in NY destroys everything and the barrels of the rims take a huge toll and it drives me insane
Are these oem size rims? Phil?
Mine Is stock and has the same problems.
I would mount a camera there facing the direction of that nut/bolt to find out if that's really what's causing it, it's awfully close though.
yeah i might try this soon last time i did a Gopro on a suspension i lost two of them i need to see how and where I can anchor it i think having the camera under the car towards the diffuser aiming at the inside of the wheel might be the ticket
I have the 2018 qv with the 5 holes and stock everything. It does not have these marks.
but are you driving the car very hard through corners like I am?
@@autofanaticcars I do push the car hard every now and then in straight lines and corners but I don't drift it like how you do on those winter wheels.
you know what will solve all this? Stelvio wheels. Been wanting to ask you for some time now, what you think about stelvio 20's on giulia. Car looks awesome with these, no problem with geting michelin 4s' + theyre bigger so probably no rub on the inside the wheel and also the et is little diferent theyre perfect flush without spacers so there wont be any rub on the inner side of the rim either.
yeah the 20s might help with some inner barrel clearances but in the NYC city area those wheels will bent and crack constantly with the bad roads and the super low profile tires. cant do that around here.
Had this same issue and it ended up being the battery terminals needed to be cleaned. Jk. But maybe grab some 5mm spacers for the rear. You do have a good bit or negative camber in the rear even lowered. Are you running adjustable upper arms?
my car has spacers it always rubbed in the rear of my car stock, lowered, with and without spacers only on the 5 hole wheels with winter tires
@@autofanaticcars very odd. First case of this I've heard of. Must be deflection in the bushings. Maybe time for polyurethane bushings? Or modify that bolt!
i might be driving into corners a bit too hard ha ha ha most likely the cause of the several squat and rub
@@autofanaticcars so I just looked into this on my personal car and the only thing that could possibly be causing that is that alignment bolt and it looks like you could take off about a quarter of an inch from the length of that bolt if you needed to
Didnt you check before you started driving? Anyway I’d suggest you get it aligned at another garage. Also the tires look like its got too much toe-out..
alignment is spot on i do my alignments 5 times per year as preventative maintenance
Put the car on a lift and check all of the rear bushings in the suspension. There is a lot of rubber that might have been damaged from the pot holes, winter salt, and mileage.
yeah we did that many times nothing looks worn or broken but it would be cool to stuff a camera inside the rear suspension to see what it does under hard cornering i bet it moves around quite a bit by design
@@autofanaticcars That would be a great idea. Would be interesting to see how different the suspension response's to pot holes, hard cornering and hard acceleration runs.
Mine Is knocking in the black tire ar the passenger side
i never figured out the cause of this issue
OK so no spacers yep its doing it under load driving forward. ..
Are you able to see any wear on the head of the bolts where you suspect rubbing?
no thats the mystery i even pulled the wheels off and i see nothing
@@autofanaticcars lol … your wheel cleaner removes all evidence!
Do you have the RUCA installed?
this has happened stock and modified only on the 5 hole wheels
Reverse the bolt setup? I’m looking today
i would try that except i still see no actual wear marks on these bolts that has me puzzled now which is why i wanted to share this video so other owners can check to see their rear wheels.
Did you find the solution?
it has to be my alignment under heavy load with the camber
Offset may
be different
Maybe zip-tie a GoPro under there and go for an aggressive drive with the car loaded with passengers.
No sign of wear on the nuts? Maybe a rock gets wedged in between on and off
definitely not from rocks this is a constant rub under certain cornering loads, very crazy
Its to close to the rim
