I went from the heavy KSport 6 pots to the mid-light 4 pot willwoods and they are better IMO. But that was for the front. For the rear it’s more difficult. It’s very limited and I don’t think there are any off the shelf options -someone might come along to correct me- as far as I know. I just had my rear callipers re-conditioned with grooved discs and they work just fine with the willwoods. The only thing that is all round on the brakes are the Mintex pads which are bloody awesome.
