So I recently fitted 19x8.5 et35 wheels (square) with 235/40/19s. I want the rear to sit slightly more flush. While researching I've discovered we need to run AT LEAST a 12mm spacer on the rear to clear the factory hub. This would essentially put my offset at et23 with a 19x8.5. I'm current lowered quite a bit.

My question is, has anyone run this offset successfully without rubbing??

19x8.5 et35 is almost flush already.... probably another 5mm spacer will do it.

When people talk add 12mm (15mm is actually alot more flush) spacer on the rear usually on a stock wheels which is 19x8.5 et47.

Et23 will rub for sure

In a perfect world I'd add less, but feel kinda handcuffed with this rear hub issue

What do you mean "to clear the rear hub"?

How are you not clearing the rear hub?

[edub370]

The rear hub is 12mm long (deep). In order to keep the wheels hub centric, you need to have a 12mm or longer spacer to clear that hub and creat a new hub. It's the reason places like ecs have thing noting front or rear fitment

I think you mistaken something... the hub is where the the brake rotors is... means you always going to clear the hub. I think what you meant by wheel fitment is that the wheel will clear the brakes calipers not the hub. The hub is where the rotors are mounted then your wheels.

a 12.5mm spacer has it's own hub for the wheel to engage, whereas a 3, 5, or 7.5mm spacer does not, thus reducing the oem hub thickness by the spacer thickness. so if you have a 5mm spacer the oem hub is now 7mm and may not be enough to engage the centerbore of the wheel. if you are using thinner spacers without hublips you can rectify the situation by using hub extenders.

[Gen13 F36]

Ah I see... so that what ecs calls that. If you use 5mm will there still be a lip to get the wheel hub centric. I think you only need 5mm to make it flush.

Lug nut conversion will help you center easier

Possible options
1. New wheels
2. Roll fenders (not for me)

Is there a reason all the hub extenders I see are listed as front? Will the rear accept the same extender? I think the front xdrives cant accept them as there is a driveshaft nut in the way, could the rear have the same issue I wonder?

Wheels are new, but I'm running a square set to keep the ability to rotate the tires. Makes life easier with xdrive, minus this situation

Correct, unable hub extenders on xdrive due to axle.

So I'm essentially SOL..? Could try a 5mm I guess

if you get a 5mm spacer you'll still need appropriately longer lug bolts.

in your photo, it appears you have a lot of negative camber in the rear, if you reduce it a little bit, the upper tire shoulder will become more flush. doing this will raise the rear height a little as well, though. however that's where you want your rear camber then, try the spacer. EDIT, reducing camber 0.5 degree is about 6mm more flush.

a future tire size of 255/35/19 would be more flush as well.

I have factory camber setting in the rear. Had it aligned a couple months back. The question was moreso aimed at the hub issue and any potential ways around that

ok, as you stated above...5mm spacer with longer lug bolts

[edub370]

So....not having the chamfered edge on the wheel side on a 5mm hub centric spacer will be ok? Wish we had the rear hub extender option like we do for the front

i have 5mm & 7.5mm turner big pad spacers, no chamfer on the wheel side. imo, it's not really load bearing so it's not necessary.

That's good to hear. Have you run into any vibration with this setup? How long have you been running it?

i have a stud conversion kit, 18" volk wheels with offsets that weren't quite right. 5mm, 7.5mm, 12.5mm turner big pad wheel spacers which i've swapped around in various combinations. 5mm and 7.5mm are used minus hub extenders because there's too much rust on the inside of the hub lip.

i have NEVER had a vibration problem caused by spacers (or ever) and have been well north of our speed limits.

will update this tomorrow. i have a 13mm spacer coming in. i did some measuring and its going to be ooooooo so tight

[blumagic]

i think you will be okay, it’ll camber in on compression. I’m et24 with a 9 but 225/40, no rub.

Correct you are! I could have honestly probably gone 15mm with this tire. But a13mm fit great
