My ITS '86 RX-7 (RWD) front/rear balance is noticably different in low speed corners than in high. For example, at Mid-Ohio I have to lift to get it to turn in the carousel or the keyhole, but I'm fighting oversteer in turn 1 (with the go pedal on the floor) - last time there I ran out of talent on the way to the tire wall.
  • Is this a "normal" characteristic, or should I be able to tune it for more consistent balance?
  • If it's not "normal", is it likely mechanical or aero? I do run a splitter (ISC) for cooling reasons.
  • If it's mechanical, what should I be adjusting?
  • If it's aero, since I'm now developing my own custom splitter design, how should I adjust it to minimize downforce while retaining effective cooling?
TIA,
