Update: Added Car Category (Road/Race). Tires are same front/rear by default (split only when needed). Ride height is shown as MIN+◯. Natural frequency / Downforce (DF) are shown as relative % between MIN↔MAX. Numeric values are shown as reference. Only if you need numeric conversion, enter MIN/MAX in the “Convert” fields (Hz/DF) below.

Input
1) Vehicle
Used to determine PP tier (A–E). If blank, estimated from power/weight.
Lap-time: slightly more aggressive downforce/toe/ARB (not extreme).
R%: --PP tier: --kg/PS: --Surface: --
3) Tires
Optional: Convert relative % to numbers (Natural frequency / Downforce)
Usually not needed. Only if you must match natural frequency (Hz) or downforce (DF) numbers, enter MIN/MAX from the GT7 screen.
If provided, the numeric output will be converted (relative % is still shown).
Damping (Compression/Rebound) uses the standard range (Compression 20–40 / Rebound 30–50). For some rally racing cars with wider limits, enable “Rally extended” in Advanced to use (Compression 20–80 / Rebound 30–90).
Natural Frequency Range (Hz)
Downforce Range (optional; only if you want numbers)
Advanced (optional)DF adjust / 4WD split / Rally damping range
Downforce is mainly set by relative % (no numeric input needed).
Enable only for rally racing cars with wider damping limits. If unsure, leave OFF (standard: Compression 20–40 / Rebound 30–50).
Output
Not calculated
Enter inputs on the left and press “Calculate”.
Natural frequency/Downforce are shown as relative % (between MIN↔MAX). Numbers are for reference.
Only if you must match exact numbers, enter MIN/MAX in the Convert section on the left.

v0.3.5: Added “Car category” input. Added Dirt/Snow tires. Default tire selection is now “same front/rear”. Logic tightened, etc.
