Was the hall floor re varnished cause it looked and felt different to drive on?
If it has maybe it will be better on tyre wear.
But other than that I cannot see an answer that would be 100% watertight
1. 17.5 turn ......... The whole club would need to buy a new motor all at the same time.... Bad ... But what about 540 gold cans not brushless
2. Blue compound tyres (not sure if they are still available ) ...... Easy to rub off the yellow dot and cheat (Elliot) Elliot you are a cheat!!!! And you would do that straight away, licking it off ,cheat perv!
3. Cover the floor ........ Difficult to setup and pack away + space to store and expense of buying! But astro indoor would be ace with mini spikes not pins so as to last longer or dboots even better wear rate!
I personally like the cover the floor with sheets of ply and push drawing pins through the tyres from the inside= lots of grip and changeable spikes lol , oh and gloves for the marshals
