You need the ones with prongs.
At only 7mm, the prongs on the hub protrude thru the spacer, so the wheel actually rests on the original prongs....

also - i presume you got longer wheel bolts to with the spacers too, correct? if not, this is a must!
Longer lug bolts came with the spacers...

Update..removed the front spacers, reinstalled the front wheels without spacers, all smooth....

Thanks for all the advice, will tackle this again in a couple days....yes they are hubcentric, yes the torque is correct, yes cleaned off any rust, yes used the longer bolts...no, there are no balancing weights missing.

More to follow, though I don't mind the "look" with just the rear spacers installed..front 7mm is hardly noticeable anyway..

Suncoast had both sets on sale for about $300, still shows on their website.

+1 was just going to say the same thing. The wheel needs to be tight to the hub like factory

Also confirm the new lugs. Ball vs. Cone seat.

Just throwing it out there. If everything you did was correct, then could it be that you just have a bad batch of spacers? Perhaps it's not as hubcentric as it should be?

I think you're right...ONE of the front 7mm spacers didn't quite go on as easily as the other three. I took the front ones off and the vibration disappeared. I ran the car down to the local PORSCHE speed shop (DunDon Motorsports) here in Gig Harbor, to see if they had any solution??

Their answer was NOT to use the front spacers, that they "were crap". Now, I've purchased items from Suncoast in the past and I've always been satisfied with their products and customer service. I will call them tomorrow to see if they will entertain refunding a portion of the "front spacer kit" which was about $122, which included both spacers, 10 extended wheel bolts, a wheel locating pin, and a new stainless machine screw. I used the new bolts in the front, as I ordered them in black, and since I'm using the rear spacers, with black bolts, I wanted them all to match..

We'll see...but for now I don't mind not having the 7mm spacers in the front, as its hardly enough to notice. The 15mm's in the rear really look good.

have a look at ECS tuning spacers. They have the extra lip and are very well made.

yeah just sounds like the wheel is not sitting on enough of the hub

Another UPDATE..

Round 2...I usually don't like being beat, so I had to try the front Suncoast 7mm wheel spacers one more time. I paid MORE attention to block sanding (lightly) the hub surfaces, as well as the mating surface of the spacers themselves.

This time the spacers slipped right over the hub "prongs", rotated freely, and appeared to have a better "fit" to the hub surface. The first time, I had to force the spacers over the hub prongs (big rubber mallet), and they were VERY tight, unable to rotate them.

Reinstalled the wheels, torqued it all down, and took her out for a test drive.

Reached about 75, hard breaking, NO SHIMMY..

Sometimes you just have to walk away, have a beer, sleep on it, and come back for another round!!

First pic, without spacers...

Also, notice amber light swapped for clear...
