I've had direct experience with two of the four mentioned, the Nissan F10 on a TCS and the Courier on an S2. Both were short term but essentially back to back with each other and the stock S2. All three had different pads which probably had some effect on the stopping power of each car. In terms of "feel", the F10 on the TCS had the nicest and plushest feel needing moderate pedal pressure to stop the car (boosters removed). Both the stock and Courier MCs were about equal in pedal pressure. Both needed fairly hard pressure to stop the car up to the point of impending lockup. I have not experimented with different brake pads on either car.
In doing my research on MC conversions for my S2, this is the conclusion that I came up (just my opinion of course).
1. The simplest and most "bolt on" is the Spitfire MC. No grinding of the MC body to make the flange bolts fit the pedal extension box and use the stock pushrod. Need to reroute the brake lines to the other side and is readily available.
2. Second simplest is the Tilton single circuit MC. Single circuit, direct bolt on as the Spitfire and relatively cheap. A bit more complicated in rerouting the brake lines in needing an additional three way union to hook up to front and back stock unions. How comfortable are you with a single circuit braking system.
3. I have first hand experience with the Ford Courier conversion but not with the F10. I believe, reading up on the F10 conversion, that both are about equal in the additional steps needed to make the MC fit. Both require grinding of the mounting holes, both need new brake lines and fittings, the F10 needs a remote reservoir fitted while the Courier needs a pushrod retaining system.
4. The last item to consider is cost and availability. The last time I checked a couple of years ago, the F10 MC was impossible to find anywhere so that ruled it out for me. The Tilton is relatively cheap and available, but I wanted to keep to a dual circuit system so the Tilton was eliminated for consideration. For some reason, I never seriously considered the Spitfire MC, wish I had. It's readily available from British car vendors for around $150. The Ford Courier MC was really cheap and available a couple of years ago. I bought mine for $25 from a vendor doing a closeout on the Cardone MCs. Do not know what the situation is now.
