The C4 has the 4 3/4" pattern that most five lug Chevys have had since the 50s. Whether those wheels will fit is based on many things, no pat answer there, such as what you consider "fit", offset, etc.

I was told there was NO WAY a 15" rim would fit on the car. 16" minimum. I Have a few sets a drag radials(15") so I was gunna pick up some rims but I don`t know if I can do it.
Another guy on this forum told me a while back that he had 15`s all the way around, skinnies up front and 15x10 out back.

The CORRECT 15" wheel HAS to fit. The 1984 was scheduled to be produced with 15" wheels. Check THIS thread, post number 46, for more details.

RACE ON!!!

These are 15 x 10 Weld Wheels with a 7.5" backspace. Don't know what the offset is.

Grinding of the calipers is necessary.

This is on my '93.

And the 87 rear rotors are a half inch smaller than Mojo's.
