Camber plate vs no camber plate

[TheRuss]

Sorry to drag up an old thread, but I've recently fitted Apex Arc-8 wheels with 235/40/18 tyres up front and I'm rubbing the struts. I'm therefore considering my options to rectify this. One of the options is to space the front wheels out and add camber plates to help tuck the tops of the wheels in. I have already removed the camber pins and added M3 tension rods and lower control arms.

My question is, will Dinan camber plates likely give me the required additional camber to tuck the wheel in? Also, how much will the camber plates raise the front of the car? I actually wouldn't mind raising it a bit at the front to even it up with the rear and add clearance.

Lastly, my car is only used for street driving, so how will adding the Dinan camber plates to my setup effect my tyre wear on the front? I don't want to end up shredding the inner edges of my tyres.

Thanks
Russ

Yes
1/4"
toe-in or toe-out, out of spec shreds tires quick. As long as you have zero toe additional negative camber causes some additional inner tire wear, but not like toe. Toe scrubs a tire away.

[TheRuss]

Ok, so they sound like an option then. Is the 1/4" how much the plates will raise the front by, or how much they will tuck the wheel tops in by? Ride height I assume you meant...?

Yes Dinan plates will raise by 1/8-1-4" inch. With m3 arms and Dinan plates you should be able to get between -2.0 to -2.5 camber. The added height plus negative camber should help alleviate the rubbing issue you're encountering.

[TheRuss]

Great, thanks. I've also got somebody lined up to roll the fenders if needs be, but I'd have preferred if these wheels just fitted as they're advertised to do.

The new EC-7s I fitted last month with 235/40/18 S04s in front rubbed on both the strut and fender sides; I had to install Vorschlag plates later that week simply in order to drive the car, and I'm still considering adding 3mm spacers in an attempt to dial out the last bit of strut rubbing during hard cornering.

The wheels are absolutely stunning, but they definitely weren't as plug-and-play a fitment as I'd been assured.

[TheRuss]

Do you have any pics of your car? How low are you?

I'm or ride about spacing mine out and running into the fenders. So far I've not touched them on any corner.

I've swapped back to my winters today and measured my tyres. The Michelin winters are actually undersized both front and rear, where the Pirellis are oversize. In fact, on the rear they're almost 280mm wide! On the front they're about 240, so only 5mm oversize.

I emailed Pirelli last week and they basically told me to to screw myself. They don't seem to want to address the fact that their tyres are way wider than advertised, and instead just focused on the fact that I'd fitted non-OEM spec tyres. Basically a bunch of robots reading from a sheet and unwilling to help.

What front wheel width is causing the trouble? I was looking at an 8.5" wheel for the fronts.

Thanks

For reference, I'm running ARC8s (17x8.5) with Dunlop Z2 tires (245/40/17).

I'm running a 5mm spacer (effectively ET +35) with -3.6* degrees of camber and rolled the inner fender lip of the fender and I finally have no rubbing.

Granted, I'm lowered close to 1.5 to 2" or so from stock suspension.

[TheRuss]

Thanks KGolf. Out of interest, do you have any photos of that setup and did you have to pull the fenders at all, or just roll them? Also, did you try a 3mm spacer at all?

We find ourselves in identical boats my friend.

I just ordered DINAN plates to alleviate or hopefully fix the rubbing/fender eating up front. Will be pairing it with a 5mm spacer to clear the strut, and VAC hub extenders to keep things nice and smooth at highway speeds. Hoping the slight additional clearance and additional degree of camber will help. If not, I’ll roll the fenders as well.

I’d really, really like to run 245/265. Bet that would feel quite neutral and balanced, but it’s going to be gnarly getting that tire to fit. With 225s I have very little room on either side as is, the front wheel well is such a joke in this car.

We’ll see!

[TheRuss]

When do you expect to fit all that? I'm still wondering if 3mm is too small a spacer to stop the rubbing. I might start by rolling my fenders and getting spacers, then try the Dinan plates last. Got a link to the hub extenders? Are they necessary with 5mm spacers?

In stages, so no promises as to when the ideal setup would be ready. Front 225s have probably 40% tread left so I’ll either run them through Summer or really hoon around for a few weeks to shred them and replace.

Let me find the link to the hub extenders, one sec. They aren’t expensive and seem very easy to install, a no brainer. Are they necessary for 5MM? hmmmm debatable. You can def notice a bit of shake on the highway with 3 or 5mm spacers, there just isn’t enough material for the wheel to mount on its own. It’s nothing crazy or overly disconcerting, but you notice it over 80mph or so. In all other situations, no I don’t notice them at all in a negative way. I’ve had enough so I’ll be putting those on soon.

I’ll have the plates and hub extenders on the car within the month; I may do M3 guide rods at the same time IDK. I’ll keep you in the loop regardless, the plates should ship today.

[TheRuss]

Cool, thanks. It says you can't use them on the rear, is that correct? Is there any way to extend the rears? I'm a little worried that you're rubbing with 225s, but then I'm running with 225s on my stock wheels with no issues and plenty of room to the strut.

Just remember stock wheels are 7.5”. So a full inch less width to deal with. The tire is not what comes close to the strut, it’s the actual wheel. With a 5mm spacer it’s no problem at all.

[TheRuss]

Oh, of course, the wheel brings it closer. Never though of it like that, so I guess it's not much narrower than a 235 when stretched kn the wheel, though the sidewalls will likely taper in more than a 235, especially a chunky 235 like the Pirellis. Do you think a 3mm spacer would work, base on the room you have with a 5mm spacer?

Yep, not the best...but is one for now. The fenders are just rolled, no pull (Illegal to do so in my class for autocross).

This is when I had -3* camber



Here is it looking at -3.6* (stock wheels)



For reference, because I'm running a coilover...I needed a 5mm to clear my spring and strut. If I wasn't lowered, I think I would be okay with a 3mm.

Here is my space I have with a 5mm:

If you remind me, i'm happy to take a picture of the amount of space I have. I checked it when I washed the car this weekend and remember being surprised by how much space I was seeing.

It's pouring out or i'd go do it now.

Yea, 3mm should work. But that's just a guestimate.

[135Pats]

This thread makes me realize I need to raise my ride height if I want to do 245 up front. Bottom line, my car is too low right now

Fak I really liked it at this ride height up front. M3 fenders pls.

[135iam]

It's really too bad that more companies don't make 245/35/18 tires. In my experience the fitment is alot better with 18x8.5 +45mm wheels than what others are having with taller 235/40 tires. Both stock and lowered the only problem I ran into was minor rubbing with the stock strut that 3mm spacers fixed. If I didn't have -2.5 front camber lowering would be a disaster though.

I have had my car north of 150mph and have noticed nothing from the 3mm spacers. I check to make sure they stay torqued and they have been good so far. I do plan to add studs in the future, just haven't ordered them yet.

My next tires will be 255/35/18's in the front with a slight roll on the fender. I am a bit disappointed with 245/265s as I was expecting the car to be more neutral (I guess since those were the 1M stock sizes)

Agreed. I think I may try pole positions next. They make a 245/35/18 that I want to run up front with like -2 or so camber and a 5mm spacer.

I feel like the oil cooler mesh is going to get destroyed on full lock though

Edit: Upon further thought and another drink, i'm going to make this work. 245 up front, 275 out back, lowered.

[TheRuss]

Yikes, you guys are brave! Thanks Kgolf for the photos. What wheels are on the car in the photo of the strut? They look black, so possibly not the Arc-8s?

Do you think a 3mm spacer would make me clear the strut, or is there likely to be enough flex in the components to still make me rub? Here's a photo of my strut clearance (or lack thereof):




Although from the two marks on the strut I'm not sure if it's just the little hairs on the tyre hitting the strut? It makes a noise when I brake, but I'm half inclined to think it's my new grooved brake discs. Will try braking hard later with my winters on and see if it still makes the noise.
