I've been reading the 'Classes' debate with interest.
It's on ongoing discussion in the UK as well.
We currently have, effectively, three classes at most UK events now;
Modified always has the lowest entries, but this years 2 Day nationals (The main BRCA events) have had 50 in open Mod (the 2 day events also have the 13.5 boosted support class)
There is also the 1 day 'BRCA Clubman's' which is arguably the next tier down, which has 13.5 boosted and 17.5 blinky.
All the carpet race series revolve around 1 or more of these.
There are other race series who sometimes include Mini's etc to help with numbers, but very rarely.
rare that 1/12 features at the same events
I think we currently have it just right, although one of the top BRCA guys thinks perhaps 21.5 blinky or similar should at the Clubmans, perhaps instead of 13.5 boosted.
We've had quite a few drivers step up to Open Mod this year, and the fact they they keep coming back seems to suggest that they aren't struggling as much as they thought they would.
I've personally found it great fun and it certainly finds any weaknesses in your setup.
The blinky guys keep saying that it's all about corner speed and accurate lines, as if boosted and Mod involves randomly driving from corner to corner
When the reasonably good Mod drivers drop down to the boosted class (they NEVER
drop to blinky), they always come near the front, if not winning.
If people enjoy blinky, that's great, but they shouldn't expect great amounts of kudos for doing it. It's always easier to drive consistently with no power, but once people have some experience under their belts, I think Mod teaches more about self control and good setup than the 'road train' that blinky always looks like.
