Let's See Your Aftermarket Wheels
I was pretty sure it would fit because others are running same size and similar offset so it was strange to have zero clearance.... Can't even put the wheel on fully.
I called the tire shop and they said they will remount one tomorrow and lower it and check.
When I had the dealer put 305’s on my stock rims they told me it didn’t fit, it touched just like yours.
I took it home and tried - yes it touched the felt when jacked up but when my stubbornness kicked in thinking there’s no way everyone on mbworld was wrong I tightened the bolts lowered it on the ground, stuck my head under the car with a flashlight and it was fine!
When you say “wheel won’t fully go on” - don’t force it - but - if it’s just the felt wheel well that’ll give and you can cinch it up.
It’s probably touching at 3 o’clock on the passenger side and 9 o’clock on the drivers side. On the ground it’ll clear.
If the shock and rim touch and the wheel can’t be physically screwed on there is something else wrong. Measure the backspace then to make sure the wheel was made right.
Hang in there - I also experienced that initial sinking feeling. Have them try again and put the weight on the wheels
Sending good vibes your way!!!
If it still is not working maybe get some 3mm quality hub centric spacers with longer bolts and enjoy life. Unless there is a bigger problem and the wheels are really ET60 by some manufacturing mistake.

As for install, the bolts went on all the way by hand, but the wheel is hard stopped on the body. The didn't really go past that as they were reluctant based on possible damage and honestly I didn't even think of the possible suspension movement because I'm used to big trucks, just figured this wasn't dropping enough for that to matter.
Gonna try again tomorrow. Shop agreed to check one wheel and lower to ground. So we'll see. I'm hopeful.
I was able to fit a business card in the gap but not a credit card. Shop basically refusing to install them because of lack of sufficient clearance. I agreed. It's just too close. If it was 5-6mm I'd probably accept it.
I'm asking the mfr to remake with a 10.5 wide wheel and 50mm offset. Basically same outer surface placement but 0.5in clearance on inside edge.

Admittedly, you have me a little concerned as I'm about to put on new wheels which are 20x11 ET 50.

What offset did you get? what size tires? I even had the tire shop put the stock 295/30 on the new wheel and still didnt have much room.
I'm currently asking the wheel mfr to remake them in 10.5 with 50mm offset. if they do, im just gonna run stock tire sizes - tire shop currently has my 275/35 and 305/30 in storage waiting to hear from wheel guy

I think I’ll have to do my own test fit tomorrow.

I went out to the garage and did a test fit of mine...
Looks like I have about .5" clearance from the shock cover boot. How in the world would a 305 tire fit in here without destroying that boot?

so far the mfr is only offering to remake at cost and I pay full shipping and te re-ceramic the new wwheel, even though HE suggested 56mm offset after i repeatedly expressed concern. Im hoping he changes his tune because I really feel like he sort of pushed me to that offset but in the end i did agree. I would rather run 20x10.5 et50 in the rear and run stock tire sizes than have issues with rubbing etc. PLUS, i have a warranty that may preclude me from runnign that larger tires size? separate issue for now but definitely on my mind
I also priced some 5mm hubcedntric spacers but then im runnign spacers, which i dont want to do, and the outer face is ion a different location that planned. UGH
As for the boot, on the inside edge i dont think the tire sticks out as far as the face side because who cares if the inner edge gets scraped etc. But on mine its rubbing even with 295's

Besides all that, if they actually remake them and the powder coat matches AND I receive them, I have adjusted the rear sizing to 20x10.5 et50 so there is no chance of rubbing and I am going switch back to stock size tires. Front fits at 20x10 and stock tires will fit on the slightly wider wheels both front and rear. Hopefully the tire shop will cancel/refund/exchange the tires. So that's the next hurdle today.
so in the end, the front fits as is with the wider tires AND/or stock size tire. Rears dont fit.....20x10 et17 front and 20x11 et56 rear. Was planning to run 275/35 Front and 305/30 Rear. Now I am going to be at the following...
20x10 et17 with stock 265/35 front
20x10.5 et50 with stock 295/30 rear

This winter I was planning on sending out my rears to widen to 11" - then with a 15mm spacer they would have an ET of 52.
Now I'm kind of nervous! If they mess up a couple mm here/there it sounds like they won't fit!
Hmph.
Is the ET really 56? Math says Bead to Mounting Surface should be around 195mm and outside lip to mounting surface (assuming "standard" 1/2" lip) should be 207mm. Did they make the wheels right in the first place?
I'm blown away ET55 works with 315 but ET56 is a no-go with 305. I guess it is what it is!

Curious to know what the collective thinks, but I happen to LOVE them!
BC Forged KL51s in Bright Graphite Grey - 20x10 ET +15 Front - 20x11 ET +50 Rear - OEM Tire sizes for the moment until I can run these DWSs out of tread.
