I've been giving thought to the business of running touring cars in the present venue, after mole2k cleaned up the week before last with his XRay, but at terrible cost.

I've realised that it might not be best to treat it like a traditional touring car race (especially on jump nights!), but rather like a rally-type venue.

Thing that don't work:
1. Lightweight shells (they get smashed - and not always by the track boundaries...)
2. Most tyres.

Things that might work:
1: Nitro shells - they seem to be made of thicker material to handle the rough stuff. They're a bit wider at 200mm, which brings me to my next point. ABS shells like those made by Kamtec may also work.
2. Wider track using offset wheels - increased stability on ultra-low traction surface?
3. Narrow mini-pin tyres - I recently learned they work better in low-grip situations that standard width tyres. Might require additive for a little extra bite. I did recently suggest metal spikes to mole2k, and not entirely in jest...
4. Plastic chassis - more flexible than carbon fibre, and can't be tweaked; especially by jumps - yes, they'd have to do the jumps just like the buggies!

In short, I think a tough workhorse like a Tamiya TA05 would perform well at much less cost than a thoroughbred racer like the XRays - yes, the XRays would be better, marginally, but the Wesleyan Hall is a surface that favours the good driver more than a good car.
