1) Ouch. 2) and fine. Then it's a level playing field and I get beat fair and square and I know why.
The sail purchase limits worked very well and I think they are worth a try here. Feel free to disagree, but please stop short of saying I 'don't get it.' You seem to forget that some of us come from other sports and even if we're newbies to car racing, it isn't our first rodeo in life and we're not idiots just because we're not running up front yet. To say that others will always outspend / etc is defeatist - why have any rules at all at that point? We have to start somewhere and this is one idea.
I see your point and I'm not going to demonize you for it. I just don't agree or that hasn't been the case for me in just over 12 years of racing.
Racing isn't fair, it's never been a level playing field and won't be. Too many variables and you can never stop the other guy from spending more money.
Tire limits, which are more common in circle track, have a downside as well. To really control the supply it turns into a single supplier source. Either the track or a contractor chosen by the manufacturer for the track/region. Been involved in that first hand and while it seems that it's a good way to go, once you do it a couple of things happen. First, you drive out the "cottage industry" or wider support from other dealers. You8r local vendor or shop sponsor probably won't be able to provide you with tire service. While we didn't get tire contingencies, we got cold, hard cash in the form of points money and per race purse. The guys that were fast were still fast. A way around the tire rule is to go to other regions/sanctions for testing using the other races. Or buy tires from a dealer and rent tracks to test. It's good on paper but at the hobby level I haven't seen an advantage. My experience is that it's a cost escalator and I've seen it decimate more than one class locally. Same with crate/sealed engine rules in classes that don't have complete spec packages.
You use F1 as a model but most of the other pro series have been using the same model far longer than F1. It works that way because the tire bill in touring pro level is an order of magnitude greater than hobby racing. First, the tires are leased, per event, meaning you don't own them or take them with you. The sanction and the supplier control the supply end to end. Last I looked earlier this year NASCAR touring series tires were $1650 per set, leased. Indycar tires were right under $2000/set, leased. Each of those series operates as a standalone entity. That's not necessarily the case with hobby level racing where one or two regions might get a fair amount of cross over. You would need to allocate tires per event, not per season to keep some teams from hoarding tires. A common rule is four tires at your first race of the season, two per race that you finish at the next event. Some are more stringent in that you can only use tires purchased for that event but that's usually only for the larger/more prestigious events and not the run of the mill local and regional events. Those sanctions do not allow for flat spotted tires. Flatten a tire or two in a set and you are usually SOL. Any replacement comes from the allocation.
I'm not trying to hammer you but "low cost" is a relative term in racing. When one jumps into what is arguably the most competitive class in hobby/club sports car racing the competition is intense. That drive the cost model. Not just for SM, but for every class with that amount of competition. One has to be comfortable in knowing both their skill limits and financial limits and schedule accordingly. To run at the front in this class on a national SCCA level is going to cost ten's of thousands of dollars in equipment, track time, and travel.
