Not read every post on here but got the general idea, I have never yet(fingers crossed big hint) raced at RHR on the dirt, I have been wanting to get up to storm valley but it's a good long day out from norwich,norfolk.
I run Norfolk buggy club, we have two tracks, one grass and one large dirt track, with big jumps, off camber corners, banked bends etc that most, but for sure not all enjoy! Most modern young drivers have been brought up on consistent grip smooth with jumps astro turf tracks or at worse grass tracks with grip. Now when they see the dirt track they go wow thats cool, then they drive it and hate it with vengeance straight away

as they find you have low grip,your 7.5 wants to make your car swap ends at every opportunity and you really do have to work hard on throttle control etc, and of course the big difference is that you need to put a totally different set up on your can than you would run for anywhere else.
So here is the problem, uk drivers drive astro, or at worse if they must grass, they don't like total change, or the fact that there normal car setup that they take from venue to venue maybe turned on it's head for dirt, they don't like inconsistency on the track and in the end in most cases if they can't drive it after practice and 1st heat they will not come back as they think it's sh*t.
Heres what I think

A) don't run rallyx and 10th same day, 10th drivers hate noisy scary rally cars.
B) keep your track fun, make sure it flows the jumps are possible and don't break cars, a great 8th track is most likely a crap 10th track and a great 10th track is a bit tame for an 8th track:roll eyes:.
C)some times open the tyre rule up a little, we did run proline holeshot only, but I'm not sure it was the best tyre so I made the rule any dirt tyre available over the counter in uk, or maybe in your case any proline tyre.
D) suger, Hmmm not sure, I have never run sugared track, Maybe as has been said try it and see but are you looking to make your dirt track run like an astro track? simple, give in, cover it with astro so it's boring
Dirts fun, different, most US club indoor tracks are small, have posts for the roof in the infield and can be low grip, one top uk driver once said to me US tracks look great, but in most cases they are crap,loose and rough
It's very hard, you have a great venue, but dirt takes a long time to get the hang of so your hard core regular drivers need to be local, as if not I can understand people not wanting to make one off journeys, over long distances to a track they are more than likely to struggle on,have a bad day and in the end practice for nothing as virtually no other meeting are on dirt in uk
