Sponge and rubber settings
I'm currently racing on rubber, but i have a super 10 so sponge is hard to get hold of, but I may be able to get some soon. Whats the difference in set-up?

RE: Sponge and rubber settings
The difference is sponge is lighter than rubber. But some rubber tires have good grip. Also, sponge has good grip. Sponge tires are alot more $$$ but there worth it.

RE: Sponge and rubber settings
oooooh yeah, found that one out the hard way! 15min of running on the local netball courts, and my foam tires are cactus! (Still run okay though, so they will do until some more $$$ comes my way!)
Sort of related question...
Tire insert types (air gap, no air gap, etc.), what are the pros and conc of both types? I drive hard and the ones that came with my car had an air gap and I shredded the tires within an hour or so worth of running. Any Ideas?

RE: Sponge and rubber settings
Generally foam tyres will give you better traction but it depends on the surface you are running on. On high grip asphalt tracks foams are the way to go but you have to take into account the type of hardness or softness of the foam. This is measured in shore and a good base line to start off with would be a slightly harder shore in the front to rear ,for example 42s front and 38s rear. There are loads of good companies that make them like Gandini,GQ,Enetti etc.
With foam tyres you can set the car stiffer then with rubbers. You would also tend to increase camber, and drop the shocks even further to get more side to side traction.
With rubbers the inserts play a major role with traction. You can either use moulded inserts or foam inserts. These will come in different densities from soft to hard. I have played around quite a bit and have come to the conclusion that the foam inserts will give you better traction at the expense of more tyre wear. HPI make good tyres for use on non prepared surfaces but on track go for Sorex or CS. As regards inserts Schumacher make some pretty good foam inserts- I use the grey ones.
Hope this helps!
