Did I read this wrong? It says "One Rim- 17 x11" Black Fits Corvette ZR1 rims Camaro C4. Does this mean only one rim, or 4. Sure seems like one rim in the heading.

What I read was the 17x11 rear of a ZR1 will for the back of a early C4, I have never bolted them on with tires to see if its true

No one has mentioned the "Big Doggie" mod yet?

Here is the direct link to the PDF: http://aurora40.dyndns.org/misc/C4%2...%20rearend.pdf
Essentially you use hubs from an 85-87 ABS rear and machine your bearing retainers down by 13.8mm. The ABS rings from your 88 and later car have to be pressed on to match up with your car. Narrows the rear end enough to tuck the 315's under without flares.

ZR1 wheels & tires
I have a 1996 Grand Sport with both Original Goodyear GS-C and Sumitomo NT555 Extreme ZR, tires on rear, 50mm ZR1 offset wheels. The GS-C's have a 11.5" contact surface and the Sumi's have 11" ctc. The GS's are 13" wide overall, vs 12.5" wide on ths Sumi's overall. Inflated off ground.
Converting MM to Inch. 1" = 25.4"
50mm offset to 36 mm offset, is 0.551" difference. Not alot but don't check and cut tires cost a lot.

To avoid confusion to the next Corvette Forum Member who may stumble onto this posting for wheels. The OEM ZR-1 Factory offset for the rear set is 36MM. For 96 the GS Rears the offset for OEM wheels is a 50MM Offset. In both of these two OEM wheels with these offsets the wheels will stick out of the rear fender wells for any base C4.
The OEM ZR-1 rear wheel don't stick outside the fender as they were 3 inches wider to accommodate the 36MM offset in the rear wheels.
For the GS the offset was covered up with GM factory stick-on Fender flares.
A deep dish wheel is not a 50MM wheel but a 36MM wheel. 50MM is mistaken as a deep dish wheel as it profile is deeper than most of the current replica offsets available. GC
