Not something you want to be doing when you are trying to attract new racers. Just getting them to do setup work on their car can be a challenge.
You are looking at foams from the point of view of a serious racer, not a beginner. Beginners are the people you are trying to attract and you should consider them. Beginners will just bolt on foams, get instant grip and be very happy to keep on racing. Tell them they have to use rubbers and unless they have the right tyres and they buy tyre warmers as well, they will slide all over the place at the start of the race and will get frustrated very quickly.
If you keep the attitude of the club as a friendly, social event with racing attached rather than winning is everything then the beginners will just bolt on the foams as new and run them until they are badly chunked or worn out. If they aren't looking at setup work then they aren't going to be interested in truing new tyres down. We make sure the priority at the club is for people to enjoy their club nights no matter how fast or slow they go and as a consequence only the top heat really sees results as being so important.
My club has run foams ever since we started running touring cars in the early 90s, because we were running foams on buggies before that and rubber tyres back then were useless. In all that time I have seen 3-4 tyre truers at the club, and all used just to refresh the tyres to get them the same diameter, not turn them down to a particular size. I used to take my truer to the club but no one ever borrowed it. If racers don't see others truing tyres they don't think about doing it themselves.
Our top drivers run rubbers out of choice, as they race elsewhere they choose to run rubbers over foam to save compromising setup or having two cars. Considering their decision was because rubbers are cheaper with less work while the novices just charge their cars and go with foams and no or little additive, our top drivers are cleaning their rubber tyres with brake cleaner, coating with additive then adding tyre warmers.
We find that once the novices get the hang of things and start upgrading from their basic gear they change their foams for rubber because those are what the fast drivers are using so they think rubbers are faster.
For those who have to tune and tweak their cars to be perfect for every single race, even at club nights with nothing at stake and whether they enjoyed their evening depends on where they finished in the final, to keep them from using foams only let the beginners run foams with the silver can motor that comes with the cheap kits. Makes them easy to drive so they can have fun and gets them into the hobby, and the one thing that sustains clubs long term is a regular supply of new racers to replace the ones that leave.
Of course if you just want to attract experienced drivers from off road and not bother about getting total newbies into the hobby then don't have a basic run anything beginners class, but don't be surprised when all the offroaders go back outside in the summer. Been there, done that, and ended up with a handful of racers in the summer. We now concentrate on those who want to race on road as their main class.
With low grip carpet and no additive, if your drivers are the ones that 'need' tyre truers for foam, the same drivers will 'need' tyre cleaner and 'need' tyre warmers, and they do make a lot of difference from untreated rubbers.
Tyre of choice on our low grip carpet are Sorex 24s for the extra grip, Sorex 28JBs easily the best if you have the grip.
And throw away your spool, all it will do is take away steering and you will have enough problems getting the car to turn in as it is. It might help traction once you are out of the corner but if you are scrubbing off so much speed into and through the corner, having to accelerate from a much lower speed doesn't help lap times.
