Just so you know the Altima MC will change the brake balance of the system. I know this because I went from the se-r MC to the Altima MC on my BABK. My thoughts are that you would be better off with the SE-R MC It is closer to the stock setup that you are really going to. Lots of racers use the NX front brakes with the stock SE-R setup. That is basically what you will have. The altima MC is going to shift the balance forward. This may not be what you need. You can get a SE-R or a Altima MC for cheap. I got my Altima MC for $20 from
www.car-parts.com. I happen to have a SE-R mc if you want to try it first. It is in good shape.
