wouldnt be so sure about other brands of chevy's fitting, that and i dont really like the look of any other rims other than the z28/ss/z24/Z06. i would look at some bmw rims, im pretty sure the 04+ model 3 series fits. but be careful on the "all 5x100" size fits all thing, u have to look out for backspacing and all that jazz. just keep ur eyes open and make sure everything fits b4 u buy anything. i dont remember what ur year cavy's backspacing is......0.42 maybe? for some reason that rings a bell.
