The biggest problem is that I'm having severe understeer during heavy braking. Eveything else seems to be fine. My front tires are wearing out before my raer. So, could there be too much weight on the front?

So, I was wondering if anybody has better suggestions or advice. I don't knwo if I did something wrong. Much appreciated.
