I just saw that there was a small wind deflector for the 90-96 ZX when I was at the ZCar gathering sponsored by the CT ZCar Club on Saturday. Had my car for 23 years and had no idea. My question is if they are actually functional. Is it worth buying a set off ebay for $40-50? I do appreciate less wind in the cabin but how much less at 60-75 mph? Thanks for any opinions.
