my 280zx feels no different in ride between 18" or 14" wheels other then the fact the steering is more sharp and precise with the 18" and it is far from a pig to drive. I have driven plenty of z cars, I have owned 2x 260z , 2x 280zx + 1 rolling shell, 1x z31 and a z32 tt, I have also driven a few more 240z 260z and z32. as for a big wheels and mods etc on my 260z that wont happen but my 280zx it is getting mods like crazy
