So I'm rebuilding my toy KaRST as a weekend car. It has Wilwood 4-pots on the front and going back together with Focus rear calipers. My plan has been to remove the rubbish Ka servo setup which has terrible pedal feel due to the flex in the bulkhead/linkage of transfer bar. I was planning using the OBP Ka pedal box but I've been having reservations recently. Can anyone comment on using an usassisted brake setup on a road car? I'm not going to need a nice light pedal for around town but it does need to be manageable. Can anyone comment on OBP kit and the use of their pedal boxes on road cars?

Thanks.
