Am I just bad or is it my rig?

I do a 2:25 on spa and a 1:52 on barcelona. I have been practicing for almost a year now and I just can't get any better than those times. I honestly just want to give up because other people are going almost 10 seconds faster consistently. It could be my setup though. My whole rig consists of a TV older than me, a shitty couch and a coffee table with a $100 wheel and pedals. No force feedback, no fancy pedals that push back. The wheel only has about 100° of rotation. I heard force feedback makes a big difference but would it really be enough to make me somewhat competitive. Even if it helps I can't afford anything like that right now. It really sucks being broke and wanting to race.
