I've put 2wd cosworth discs and pads on the front of mine yes it stops a lot better but you car'nt have standered wheels on the car. the problem is the plastic nylon bushes in the bar what go's across the bulkhead if these are worn and with the twist in the bar the brakes are
crap. You can go the s1-s2 way with there bars but it will interfere with the induction pipe. i am looking into doing the brakes on mine again by taking all the bars out and putting a rally kit back on,meaning i can put the servo where ever i won't to. more details later on in the year
