C4 Wheel Weights

[Pat F.]

This question pertains mostly to the C4 Classification, but any comments or prior information is greatly appreciated.
At a recent Chapter Meet, a 1996 Grand Sport (GS) with about 10,000 miles was presented for Flight Judging. It was noted that the wheels on the GS had the glue on type of wheel weights pasted inside the wheel. It was felt that the correct type of wheel weight for this GS were the clip on type. The current owner stated that he had purchased this GS with 500 miles on the odometer and the weights had never been changed. We all know what can happen when a prior owner is involved.

Another Chapter Member also had a 1996 GS and thought that his GS had the paste on type but the GS was not readily available for inspection.

I have contacted a number (Experts-?) of individuals concerning this matter and no one can remember any Corvette coming from the factory with paste on wheel weights,

Any comments would be greatly appreciated.
I am posting two photos (First not that good) of the paste on wheel weights on the 1996 GS in question and the second photo depicts what I would call normal factory wheel weights, but I could be wrong as in the past as it is pointed out by friends on more than one occasion.

Thanks

I don't have a definitive answer for this. However, I can tell you that GM says that no self-adhesive weights were used for 1996 Corvettes. From what I can determine, self-adhesive weights were first used for certain wheels for 1999 Corvettes. However, I believe the style of self-adhesive weights used for 1999+, GM #9592827, was similar to the style of self adhesive weights seen in your photo.

Re: C4 Wheel Weights

Joe, thanks for your response. I do appreciate your time and effort not only to this thread but to all of the threads you have submitted useful information.

Re: C4 Wheel Weights

Pat, FWIW, my original-owner 96 came from the factory with clip-on wheel weights similar to your second photo.

Re: C4 Wheel Weights

Folks, I want to thank all of you for your time and interest in this thread. I have gotten a couple of emails with responses that have not been posted to the Board as of yet. I mention this because my thanks go out to those folks also. We were just trying to help out a member who has a very low mileage 1996 GS and is going to go further in the judging process.
Again, thanks

I did a little more research on this one. I found that self-adhesive weights were once cataloged for earlier C4. They were first cataloged in 1986 for 1984-86 Corvettes. Thereafter, each model year was added through 1991. However, there were also clip-on weights cataloged for each model year. So, just how or when each were used in PRODUCTION I do not know. This weight was GM #14080297. It was a 3 oz weight with 0.5 oz segments that could be cut. It was discontinued without supercession in March, 1998.

The other self-adhesive weight I mentioned above was used for some C5's. It was also a 3 oz weight with 0.5 oz segments which could be cut off. It was GM #9592827 but I do not know how it differed from the 14080297. It's also GM discontinued. There's probably a replacement part number but I don't have it. Likely, the replacement is zinc material rather than lead.

Re: C4 Wheel Weights

Joe, am I reading your previous post correctly in that it was possible to have both self-adhesive and clip on weights on the wheels of Corvettes from 1986 through 1998 and then with a different self-adhesive weight for some C5's? If that is the case the self-adhesive weights on the 1996 Grand Sport maybe correct?
Please let me know if I am misreading your comments.

No, GM cataloged self-adhesive weights beginning in 1986 but back to 1984. Then, they continued to catalog them through 1991 for 1984-1991 Corvettes. However, for that same model year range, they also cataloged clip-on type weights. So, whatever type was used in PRODUCTION for any particular wheel is not known from this. GM never cataloged such weights for 1992 to 1996 Corvettes. Of course, that does not mean that such weights were never used.

A different part numbered self-adhesive weight was first cataloged for C5 Corvettes in 1999 for certain wheels. However, it was then cataloged for 1997+ Corvettes. Once again, clip-on weights were also specified for 1997+ Corvettes. So, which type of weight was used for any particular car is uncertain.

Re: C4 Wheel Weights

I'm the original owner of my early VIN '84 and I definitely remember that the wheel weight adhesive was changed for '85 due to it peeling the clear coat off the wheels when the weights were removed. My originals were clipped on+adhesive on the outside of the wheel lip.

Re: C4 Wheel Weights

Joe, I was able to enlarge the photo of the self-adhesive wheel weights on the 1996 GS and they were 1/4 oz segments with a 7 GM underneath the 1/4 oz marking.
This does not agree with the information that you provided that the weights were a different weight per segment. We will continue with this until we can add or subtract the correctness of these weights.

I was incorrect regarding the segment size. It should be 1/4 oz, not 1/2 oz.

Re: C4 Wheel Weights

This is possibly far fetched but you never know. Does anyone have the VIN for the GS that has the stick on weights ?? Here's a far fetched possibility, but if you look at the cars used in the C4 brochures, you never see wheel weights in the pictures. Since the owner of this car bought it as a low mileage pre owned car, could it have been an early production "photo shoot" car ?? Or are the wheel weights photo shopped out of the photos GM used ??? Just a thought. Could stick on weights have been used on photo show cars ???? Just askin.

I missed the fact that the weights on the car in question apparently have "GM" embossed on them. If that's actually the case, that throws a different light on things. That would mean that these weights were supplied through GM. It's HIGHLY unlikely that any tire shop would have used such weights. I see only 2 possible reasons that this would have occurred: first, that they actually were installed in PRODUCTION and, second, that the original owner complained about wheel balance and the dealership re-balanced them in-house using self adhesive weights supplied through GMSPO.

Re: C4 Wheel Weights

I can't speak for all C4 Corvettes, but I can speak for my 1992 LT1 Coupe. I am the original and current owner. Please see the three wheel weight photos. Each photo is a different size and weight. They have been with the car since I took delivery in July, 1992
