Hi Ciaka and all,
I just bought 4 spacers from adaptec. Take a look at , 15mm and 10mm. I also wonder about the 2 small holes for the screws going to the the rotor. Do I have to remove the 2 screws from the rotor and attach the spacer to the rotor? Thank you for your input.

 

Nice. Those screw holes wont be usable unless you find screws long enough to go through the spacers and rotors.
Most likely you will keep the screws where they are now, and put the spacers over top of them. No big deal.
Good find.

 

Thank You, Ciaka for your input.

 

I did the exact same spacer sizes and it worked out great

 

Can't seem to find 44mm bolts, anyone know if 48mm would be too long with 15mm spacers all around on a 970 PTT?

 

That is 4mm difference, less than half centimeter, or less than 1 sixth of one inch. Seems like should fit, but I cannot guarantee. Lugs too long would go through hole and th ouch the RV of shield on inside if wheel. But 4mm seems like small difference

bought m6 30mm flat hex screws from homedepot. $0.95/each they are good ... long enough to go through the 15mm spacers and rotors.

 

Those replaced lug bolts perfectly? my ECS tuning bolts don't get enough past spacer.

 

I cannot find the 44MM or even 45MM lugs to go with the 15MM wheel spacers to save my life. Anyone have a current source/supplier?

(H&R Special Springs makes bolts. Found those on their website locator).

Hi all
i installed 15 mm spacer and I do have 20” turbo wheel on my Panamera too. It looked great but I have an issue the care vibrates at speed over 120Km/H. Bolts are tightened a few times to make sure they are tight enough.
I am thinking to remove the spacers but I love the look.
any feedback appreciated
thanks

 

I, too, have 15mm spacers on all 4 corners. I have no issues with wheel vibration at any speeds.

1. Are your spacers hubcentric? If not, this might be the issue. If you’re not using hubcentric spacers you will need a wheel alignment.

2. Make sure each and every lug bolt is torqued to 118 ft/lbs.

3. Are any of your wheels bent? Wheel balance and alignment could be the issue too.

4. Is there any play in your wheel hub?

Lots of possible reasons. I’d start with the simple things first.

 

I have no problem or whatsoever with my 15mm spacers in the rear, 12mm spacer in the front. they are GREAT !!! did you install and torque it correctly?

 

If there was no vibration/wobbling before installing them, it's likely to be balancing. The wheels are now 15mm further out from the hub accentuating any imbalance. I would take them to get balanced and ask the wheel techs to get it as close to perfect as they can.

 

This happened to me as well. It needed balancing. I was like no way it needed that and it wasn't shaking before the spacers were added. There's some odd, maybe coincidental reason that when disturbed and the wheels are removed...or maybe the spacers amplifies any slight imbalance? Not sure, but definitely look into getting the wheels/tires balanced.
