in LFS?
sure there are, compare the FZR's times to everything else and you'll find that it is faster in pretty much every situation, and the FXR you'll see is usually the slowest except on the smaller tracks
looking at WR times; while the XRR and FZR may be close.. its still unfair, while the FXR is a whole seconds slower for its WR
i still say no because its unrealistic; nascars dont have that many differences in them
what we need is the N/A power of the FZR, and the looks of the FXR lol
