The main car that the FR-S copies is the S13 240SX.
2700 lb.
~54/46 static weight distribution
FR rwd/irs
2+2 coupe
modest N/A 4cyl power versus higher-dollar/higher-end sports cars of its era.
240SX had only just over 50% of the 300ZXTT's power, FR-S has 60% of the 370Z's power, so some improvement there

We also get a torsen lsd (only a very few HICAS S13's came with LSD, and it was viscous)
But the FR-S mechanically is a near verbatim copy of the S13, which is FANTASTIC as far as I'm concerned. And it looks way cooler
