Yes the Corvette rear suspension can be narrowed but it may require modifying the attachment points for the rear suspension (i.e. the forward trailing link points will be too far outboard if you narrow the rear suspension. Also the front suspension cannot be narrowed unless you modify the front crossmember and the steering rack. If this was my car I would not attempt to modify the frame. The EM frame is very well engineered.

I would just get some Team III wheels or PS engineering wheels made to fit my suspension. If you call Enzo at Finish Line he should be able to help as he used to have a EM cobra with the corvette suspension. He is also a Team III dealer.
