The GTO Spare Tire for C4s with C5s Brake Kits
I removed the spare tire on my 96 Vette long time ago. The 3.91 gears on the 96 helped to reduce the drone at freeway speeds
but, last week I drove 250 miles around the east San Diego mountains and by the time I got home my head
was tingling. The Magnaflow drone was there for over three hours and Im about to purchase a Corsa Exhaust System.
I was wondering how come the Magnaflow muffler drone on the 95 is almost non-existence. The 95 still has the spare
tire on place and it has the Weather Tech rubber cargo liner and I was thinking this may be isolating the drone.
The 96s spare tire never worked, it has an air leak since I bought it and due to fact it has the C5 brake kit the OEM
spare will never work. I decided to give the Magnaflows on the 96 one last chance and I bought a GTO spare tire.
I hope once I get it installed some of the awful drone goes away and I dont have to spend $1,200.
The C4 spare tire on the left and the GTO spare tire on the right
It still in great shape with plenty of tire tread left.
The C4 spare tire would go in all the way in but, it rubs on the C5 caliper.
A look from the inside.
Points of contact
The GTO spare tire.
Plenty of clearance
I was lucky I kept the carrier. I cleaned it up and gave it a coat of undercoating. I saved all the hardware but, could not
find the carrier bolt.
I may have to order a carrier bolt, once I get I receive it I will post the results of this "experiment".
For you guys with C5 brake kits, the GTO spare tire is an alternative you could consider.
The GTO tire 145/70-17 and the C4 tire 155/70-17 are expensive but, is not impossible to find.

This is one of those things I love about this and other similar forums.
The ingeniousness of the posters. This is a perfect workaround for someone who has done this. I could probably safely assume that more than one person put on C5 brakes on a C4 and found the stock spare wouldnt work. This works.
Maybe GM should hire some folks on here, for their engineers..
A lot would be better.

I was thinking about getting a couple of those GTO wheels for drag racing.
I could probably knock off a tenth or 2 with those. What do they weigh?

I know the drone issue has been beat to death, but is it possible maybe the center resonator could be changed to a Corsa, after you try this test? I know the OEM and the Flowmasters cat back that didnt drone. Or, it might be hearing loss.

I received the carrier bolt and got busy with this project.
Got the carrier back up there, shame it looked so nice there without that crap. I was going to make
a plaque with the skull screwed to the monospring bolts.
I was a bit concern about the GTO spare, its offet if bigger than the OEM tire and I thought it would hit
the fuel tank.
ALL CLEAR :seasix:
I also had some heat wrap left but, not enough to do what I had in mind.
This is how it looks now with the GTO spare tire. No Dana 44 visual though.
Next--
Few months ago I ordered projector lenses and today I took the HID/diamond headlights off. I re-used the
HID bulbs.
They do look cool dont they? :seasix: Yes, they look cool during the day BUT, they SUCK at night. I had three
times the brightness with the other headlight lenses. I will reinstall the old ones back.
These are the worst headlights I have ever had in my driver life. DO NOT BUY.

I can see why those new headlights didn't work very well. They made the reflector black/dark colored. I guess they didn't understand that black doesn't reflect hardly any light?
Oh, and Pete, I'm looking forward to that April run!

Looks good! I know several people like the GTO spares for front runner drag wheels.

If a lurker (Learning as much as possible before I buy a c4) may jack the thread.
Is that a max jax lift?
If so why did you cut the floor?
I have been thinking about getting a maxjax.
Thanx!

Oh, and nice Vette!
