here the steps for demo racers (without wheel):
-buy S2,
-go to an online shop and buy a wheel of your choice (for beginners i recommend the formula force ex, its cheap and FFB is good)
-make sure you really have bought s2
-eat something
-look at your order status for your new wheel
-activate your s2 account
-wait some days and have a surprise how good the feeling is with a wheel in combination with s2
its just joking, but i can recommend following wheels:
-logitech formula force ex (cheap wheel with good ffb) about 40 €
-logitech dfp (good wheel, many buttons, excellent ffb) about 90€
-g25 (the heaven of racing!!!!) about 230 €
-911 (good wheel with good ffb) dont know the price, but i have heard only good things about
