which TC?

I hope for your sake that your club chooses to run rubbers as foam are a pain in the jacksy.

Biggest issue is that the 28mm wide ones (which are the common American size) are not an easy fit on quite a few of the chassis out there, you have to cut things up of swap parts over (most of the Japanese cars except the HotBodies need a lot of tweaking for foams to fit well).

Second nuisance with foams is that as they wear they decrease quite significantly in diameter, throwing your gearing and suspension settings out all the time.

Rubbers are a shade slower around the track but still grip, feels just like tarmac racing to me. I much prefer them.

Apart from the wheel fitting issues, foam-spec cars tend to have stiffer chassis and springs to make best use of the extra grip, and tend to run a front diff also. But most UK clubs on temporary tracks never get up to the level of grip that the foam cars are built for (ie permanent US tracks soaked to the skin with additive), so rubber spec cars will be just fine for most people.

So I would wait until the announcement on tyre rules before splashing the cash. The good news is that pretty much every car on the market right now is good enough to compete.
