I just bought a 1994 Z28 Camaro, the rear tires are rubbing really bad on the inside of the wheel wells, i have stock rims and tires on the car so i dont know why it is doing this. Also it has rear drum brakes, i didnt think that Z28s had drum brakes. I am thinking that the person before me put on a different rear end, how do I identify what kind and year the rear end is that i have? Any help would be appreciated.

 

Sounds like someone swapped in a 3rd Gen rear axle assembly. All the V8 4th Gens had disc brakes and a limited slip differential. The stock 16" x 8.0" 55mm offset wheels were nowhere near the inner fenders. The 3rd Gen rear is 2" narrower on each side, which would put the tires way into the inner fenders though.

 

Thats what i thought but just wanted to make sure. Is there anyway of searching the numbers on the rear end to tell what it actually came from?

 

Also would it be ok if I put on 1 inch wheel spacers on each side or is that a bad idea?

 

Sure why not? Def better than having the tires rubbing all the time. I mean, plenty of members with aftermarket wheel/tire setups use spacers with the OEM rear end (for this exact reason) and run just fine (myself included).

 

When 3rd Gen owners want to use 4th Gen wheels, they run 2" adapters (not spacers). The adapters bolt to your studs, and provide a new set of studs to bolt the wheels to. Much better than attempting to use a spacer and longer studs.

 

OP so u can see them, mine are like these but are 1.25"...http://cgi.ebay.com/ebaymotors/2-1-2...item3a6a44fe49

 

I meant adapters not spacers, sorry. I just picked up a set of 1.25" worked perfectly, we'll see if the rear end holds up to the LT1 power.
