Personally i would stick to driving just the classes you intend to race. I have a touring car (
sorry guys) which gets used on club nights for a bit of fun but it also keeps your thumbs alive.
I did start doing 18th but found it awkward adjusting my driving style back to 10th quickly. Drive a 2wd car on slippery/greasy offroad tracks. That WILL improve or driving. If you can go fast with a 2wd in winter, 4wd should be gooooood
