1991 ZR-1 looking for a Spare Tire Delete...

[Paul in VA]

Hi All: Any of these out there ?:flag2:

[Kevin]

can't say i've ever heard of this. couldn't you just remove the tire/carrier?

[FU]

Are looking for the aluminium brace ?

[Paul in VA]

Yes... sort of. I think there is a aluminum I-beam that replaces the spare tire. It spans the gap left when the spare is not in place. The concept with the I-beam is to provide the resistance (in a crash) that the spare tire provides normally. My understanding is that the spare tire is an essential component in rear end crash protection. It's strength/size/mass/whatever is critical to surviving a rear end type crash.

[Kevin]

i've heard the theory that the spare tire is part of the rear impact system and I'm not sure that I buy. I don't see the ntsb allowing something that can be easily removed to be part of the crash support system.

for example, if you blow a rear tire, you won't have anything there to absorb the impact of the crash if the theory is to hold true

[FU]

I have the spare tire delete that you are talking about. Also have a spare one that's new.....not that new would matter.

[FU]

PMed.

[Paul in VA]

PMed back.

[Kevin]

well i was wrong

[Helium3]

I could use a spare tire delete as well...I know this thread is 2+ years old...

[FU]

They were sold.

A aftermarket one was mfg by Corvettnutz I believe I think Craig bought one. Quality piece from what I recall

[cvette98pacecar]

I do have one that I can take to a trailer manufacturer that lives by me and can get a price if we have enough members that are interested.

[USAFPILOT]

does it weigh less than the spare?

[JimZRyd]

I remember seeing a pic of a DRM GS that had a really nice looking polished spare tire delete bracket. Thought it looked pretty slick. Been thinking of removing my spare to expose the rear suspension components and get them all cleaned up and detailed. Wonder how visible the bracket really would be and how much it would cover. Ill try to find the pic I had and will post it up.

Rick is right, there is an aftermarket option. I do have an OEM NOS that I will sell when I get back to Hawaii since it does not fit the early model Zs.

Here is the info on the one from CorvetteNutz:

these spare tire delete brackets are NOT a simple bolt on process. for 90-93's you have to remove the rear bumper cover, for 93-95 you have to drill holes to attach it. i had a couple of these but decided not to install since i didn't want to butcher my cars

That is interesting and no wonder I did not install the OEM one on my 90 MY. All I did was put it up there to see and it was clear to me the frame is a little different based on the photos I saw installed on later model with the spare tire delete option from the factory.

The aftermarket one from CorvetteNutz was very easy to install. I guess Rick could chime in on the OEM one he installed on his 95 MY (blinged out with custom graphics I might add). I have no idea what it would do it called up in a rear collision versus a spare tire and hope I never find out.

[JimZRyd]

This is the pic of the one I had saved on my desktop. Not sure if its the one mentioned from CorvetteNutz but I think it looks pretty good and will probably go this route sometime in the future myself. Does anybody recognize who makes this one? Is it CorvetteNutz?

Jim,

That is the OEM one and being you have a 94, you should be good to go with that one if you can locate one. I will have one for sale later next year once I get to all my items in storage and get back to Hawaii. That OEM item is like finding a Unicorn these days.

Craig,
Keep me in mind when you return and if you plan to sell yours. Did you ever use it or just picked one up with future plans? Is the one mentioned from CorvetteNutz of equal quality? Not trying to highjack thr Op's thread but I'm also interested in this mod. Thanks!

Hello Jim,

I don't want to make a commitment to anyone for this item, especially since I don't know when exactly I will go back (pending a job to extend here). But here is some info I found about it if you want to try to locate one in the meanwhile: Part number 10265938 - described as RR BPR IMP BAR - GM part book at 7-K4, item 36. The bolt is 11504611 - M8X1.25X20 (four needed)

I think I saw where Robert was going to possible try to get the OEM one duplicated? They show up every once in awhile. I want to say mine was special ordered from gmpartsdirect.com some years ago. It is new and never installed. I could not figure out how it would mount to early model year cars even with bumper cover removed so I decided not to mess with it. Best wishes. :cheers:

does it weigh less than the spare?

It definitely weighs less than the spare. The CorvetteNutz one weighs about 11 pounds according to them, but I thought less and should have weighed it before install. Not sure what the OEM one weighs, but around the same and quite light.

According to Marc's site about weight reduction:

Spare 37 lbs
Jack 6 lbs
Jack Handle 2 lbs
Tire bag 3.4 lbs
Spare tire carrier and brackets 9.5 lbs

So I guess it depends on how much you will remove and what is added back in because of no spare (like a fix a flat, etc.) I wonder how it affect balance of the car or traction?

Craig :cheers:

[JimZRyd]

No worries Craig and thanks for the info! I'm sure if Robert made a duplicate model it would be of equal quality, if not better!

Jim,

You could also consider contacting Shaun "Sparky" and he is great to work with. They have a lot of R & D on this and has a lot of knowledge about what and why it seems:

In late 93 they put two holes in the center of the rear sub frame/cross member not a different design, just added holes. I've heard many people talk about 94-96 difference, it's just the rear impact bar. In 96 was the only year for the impact from GM for the run flats. I'm still yet to see run flats on a 94' 95'. The main reason for the hanger bracket on our design is that it should align up with all 84-96 rear spare tire hanger brackets

I will be home on Wednesday night. I will run to the shop and see what the guy wants to replicate the tire delete that I have. I will also include photos.
