need help with installing 18" rims on my 1984
Hi Guys
Finnaly I got the panamera 18" rims .
I tried to put the current rims and tires just to take it to the shop to install the new tires ( rear has now 275/45/18 - I know it should be 265/35/18) the rear tires are touching the quarter panel - when ill put 265/35/18 will it fix this issue or I will need spacers?
Front lugs (aluminium) cant be opened and 2 of the heads broke - see photos.
Any ideas how I can take them off ? ( already spayed WD40)
rear lugs came off no problem
THANKS guys

Can't help you with the seized front lugs - but, WD 40 is not going to help much either. WD 40 is Not a penetrating fluid - try something like Kroil, PB Blaster, or (best) a 50/50 mix of acetone and ATF.
If you are trying to fit the stock Panamera wheels and tires to your 928 to drive it to the shop, it's not going to work.
The stock Panamera front wheels and tires won't even fit in the front wheel wells. The rears will physically fit, but they're way too tall and they will rub.
It also appears that you still have the 27mm spacers on the rear, so it's going to rub even with the new tires (the 2" wider wheel with a 53 ET should give you about 1/2" clearance to the fender lip with 265/35 tires - add a 27mm spacer and you're going to be about 1/2" too wide to fit inside the fender lip on each side).
You may also need to use "open" lug nuts on the rear. After removing the spacers, the lug bolts may be too long to use the stock alloy "acorn" lug nuts. Not sure about this as I've never attempted this on a car with the longer lug bolts, so YMMV.

Ill try penetrating oil.
what should I do in order to fit the rims?
I was told it will be an "easy" direct fit , can I take the spacers out of the rear?

Slide the spacers off the rear hubs and use open ended lug nuts in place of the closed ended. Or you can crank down on the close ended nuts until they snap the center off and then torque them up. Works but not ideal.

The rear spacers are "hub centric" and likely corroded in place, so you may have to drive something like a putty knife or a (expendable) screwdriver between the spacer and the rotor (e-brake drum) to separate them.
There may be enough of the front lug nuts left to get them off with a deep 19mm socket. You are turning them counter-clockwise (lefty loosey) aren't you....?

The rear wheels can be made to fit no problem as indicated by Sean by removing the spacers.
How you managed to break the front nuts is a bit beyond me other than from partial engagement of a socket. If you get full engagement on what is left with an impact socket you should be able to get the residual nut off off but dose it with a penetrating fluid and leave overnight first. Once you get those things off you might be able to clean the damaged ones up and cut the ends off the others to leave you with a set of open ended nuts that could be used on the rear wheels if the metal is not torn deeper.
I did something similar on my rears when I had to remove the stock GTS 38mm spacer and replace it with a 24mm spacer to make my non stock wheels fit. The open studs may bother some but it does not bother me at all.
As I remember the Panamera wheels in 18 inch diameter are typically ET59 and 8 inches wide. Your rear rubber is not really suitable for the 928 but a 275 on an 8 inch rim? That rear rubber has something in the region of a 27.8 inch diameter whereas the 928 is designed for a nominal 25 inches.
If your rear rim is 8 inches wide [asI suspect it will be] then you need to dump that rubber as such would not be considered safe. If the rim is wider fair enough but do you really want to run with a 27.8 inch diameter?
Perhaps you can confirm wheel sizes, offsets and rubber currently fitted then we can advise you better if you so require.

The 18" Panamera wheels are:
Front 8" ET 59
Rear 9" ET 53
He has (or is getting) the correct size (new) tires (from an earlier post): https://rennlist.com/forums/928-foru...984-928-a.html
Front 235/40
Rear 265/35
These tires give him a tire diameter of 25.4" front and 25.3" rear - as close to optimal as you can get.... The used Panamera tires that came on the wheels he bought simply will not work - as I've pointed out previously.

The aluminum lug nuts can certainly sieze. It happened on my car - ask Stan as he had to deal with them when he installed Bilsteins on my car.
As documented in other threads, the nuts have to be drilled out with a hole saw, taking care not to damage the studs or the wheel in the process.

I guess the aluminium got "stuck"/ infused to the metal stud.

For the rear lug nuts get the steel ones from your local autoparts store. Take one of the existing lug nuts with you to make sure you get the correct type. Put the steel lug nuts on and torque to spec. Then put the existing aluminum nut over that and torque to 40ftlbs or so. No need to go any higher as you just want to keep them from falling off.

As you are shopping for lug nuts, look carefully at the rounded shape of the end of the lug, where it mates with the cup in the wheel. Your replacement lug nuts need to have the same shape. Generic parts-store lug nuts with a single-angle end are made for steel wheels, and won't do with your aluminum wheels. Our sponsoring 928 parts vendors can guide you on this. I know specifically that sponsor Pelican Parts carries the correct open lug nuts for your wheels.
For removing the old nuts that you've broken off: The recommended procedure involves a heavy-duty electric drill and a hole saw. You'll pull the pilot drill out of the hole saw, then slowly and gradually use the saw to remove the last of the end of the lug nut. Challenges include knowing when to stop, as you are cutting through the aluminum nut but want to stop before the saw touches the aluminum wheel. Else the saw will ruin the face of the hole where the lug nuts seat, rendering your wheel to scarp status. I've done a few for clinic cars, and found that a little bit of hole-sawing interspersed with a small bit of "reverse" will sometimes get the last bit to back out before the saw gets to the wheel metal. Patience is of paramount importance, as is good sharp hole-saw blades.
