What kind of wheel weights did Porsche use -- '82 928S?

[ed45626]

Just got my tires mounted and balanced, at a local shop specializing in Porsche / BMW / Mercedes.

Picked up the car and it's got clip on style wheel weights -- previously had stick on style.

The rims are the stock slotted Porsche rims -- anyone have any idea what Porsche originally used or if they ever used clip style? Seems odd -- my wife's 2005 Ford Focus doesn't have clip on weights!

Also -- any thoughts on the effect the clip weight has on the rim? Is there a protective coating?

Take it back to them and have them put stick on weights on the inside of the rim. Then kick their arse's for putting clip-on weights and damaging your aluminum wheels.

Best to discuss this up front as some shops are snotty about clip wts which are cheaper and easier to use.

Not a clue on what was factory, or if it varied, but I won't accept clip wts on anything I own.

Clips are steel springs, wheels are aluminum, damage is permanent.

The stock rims are definitely capable of accepting clip on weights, but I haven't used them since I bought my car. They look like hell and always gouge the finish and/or wheel itself when installed. Stick on type has worked just fine for me.

Here is a picture of a (prototype) 928 in the Porsche Museum, and it has the clip-on style. So I doubt there will be any damages from them, but look-wise i'd go with the stick-on's too.

Yes, I've seen plenty of original 928's with clip-on weights.....They were used often.

But, nowadays, why would a technician even use Clip On weights anymore....???? There's absolutely no reason to.....Stick-On's are SO MUCH EASIER.

Peel.....stick....done!

Clip on wts are cheaper and easier to use, a big reason for the installer. Clip on wts attach to the rim vs inside of the wheel, and the distance from center allows less wt for the same balance. Clip on wt takes no prep, place on the rim and hit with a hammer. Stick on wts require cleaning the inside of the rim, maybe scrapping off the old wts, and since placement isn't as exact, it may take a couple tries to get a wheel fully balanced.

I thought those new fangled wheel balancer machines actually mark the rim where the weight goes, plus give you how much weight to stick on? Since before my 928 days, I've "always" told the tire guy to mount the weights on the inside. This is pre-stick on days.

Either way, you still need to drink a pint of Jack Daniels and get all yoked up and kick that tire installer dudes arse.

Usually the tech needs to set the location of the two stick on tracks inside the wheel manually, this combined with the width of the wts and the shorter distance to the center of the wheel make accurate placement less likely.

I'm gonna go on a limb and say they used lead wheel weights.

A good tech can get away with mounting the the clip ons on the back side of the rims.

When I was an auto technician, (yes, it's true) clip on weights are a little cheaper, but I never used them on aluminum wheels (or, extremely rare when I did)....but, then again, that's me. I am a bit anal when I work on other people's cars, and didn't like to make marks on wheels if I didn't have to.

Clip on lead weights are fine on the inside of the rims. That way, their new fangled machines are still accurate and you don't have to trust some bone head to prepare the inside surface of the rim (where all the dirt and brake dust lives), so they don't fly off while you are driving.

I've actually had a bone head tire guy put clip ons on the "inside" of my rims and they still flew off. It's all that remove and reinstall that expands the clip so it no longer holds well. I've had good luck with the Big Tire Guys (Discount Tire, Evans, etc). Best to stick with them as their rep is on the line. They are "only" places that will ever touch my powdercoated wheels as well.

Having just gone through a problem with balancing on my truck, I discovered that the outer and inner on most wheels must be balanced. The shop that hooked me up put clip ons on the inside outer lip, and then stick ons on the inside of the rim, near the outer face, and all my problems went away.
