The proposal is simple: break down R and P classes by increments of 25.
Now:
- R class: 801-900
- P class: 901-998
With the breakdown:
- R1 class: 801-825
- R2 class: 826-850
- R3 class: 851-875
- R4 class: 876-900
- P1 class: 901-925
- P2 class: 926-950
- P3 class: 951-975
- P4 class: 976-998
These new performance classes could be an addition rather than a replacement, in which case you could still set races to R (and P) class with a PI range of 801-900 (and 901-998), or use a more restrictive sub-class.
Why?
Most performance classes represent a span of 100 points of Performance Index (PI), with a few variations.
Race cars are largely concentrated in the R and P, and they generally have few upgrades, and can’t (or sometimes can but probably shouldn’t) be upgraded to the max PI of their class.
A number of production cars have a similiar issue, particularly in the Modern Factory Racecars and Modern Hypercars divisions.
This isn’t so much a problem for spec races, but this isn’t an option in Free Play or in Rivals. Having more granular classes would save a lot of time in setting advanced Free Play races, and would allow more cars to be useable and competitive in open Rivals.
